Turbo Installed. Wont Start. HELP!
 

Well I finished everything today. 450cc dsm w/ smc500, walbro 255lph pump, 10watt 10ohm resistors, d16y7 block. When I go to crank it just keeps turning over but doesnt catch. Pulling the plugs revealed that they were covered in gas. So somehow I flooded I guess. Settings were -35 across the board. What should I check? ???

Re:Turbo Installed. Wont Start. HELP!
 

way too rich, flooded your engine, and washed your cylinders/rings=no compression now. pull your plugs and let cylinders dry out for a day or so and get new plugs. drip about a tsp of oil down each plug hole to recoat pistons/cylinders to regain compression. set your low throttle settings to -47 or -46. -47 correction will=approx 238cc inj and -46=appox 243cc inj. use this at least for 1k rpm. don't need much fuel to start the car.

Re:Turbo Installed. Wont Start. HELP!
 

btw...when you start the car after doing this it will smoke like a mofo. hopefully your car isn't in a garage, or if it is make sure you have a fan handy to blow out the smoke...cough-cough.

Re:Turbo Installed. Wont Start. HELP!
 

So what should I use for my idle/running settings?

PS. I need to get this started tomorrow. Car has to be out of the garage I am using. :(

Re:Turbo Installed. Wont Start. HELP!
 

good luck man

Re:Turbo Installed. Wont Start. HELP!
 

you know what happened?

ok first, 450cc gives rich with SMC settings at -35... ok.. thats' one thing.. and when you "primed" your turbo with oil, you should have pulled the INJECTOR FUSE as well, i know you pull the spark wires but you were still sending huge amounts of fuel... you forgot to pull the injectors

Re:Turbo Installed. Wont Start. HELP!
 

Should I be running much leaner settings than most of you guys since I have a bigger fuel pump? Or does it not matter. I dunno seems like its just a constant fuel bath. ::)

Re:Turbo Installed. Wont Start. HELP!
 

Could someone tell me a little more about priming your turbo for the first time? Do you guys just leave the oil feed line off until you see oil come out of it?

Re:Turbo Installed. Wont Start. HELP!
 

sounds like you don't have spark for some reason.. Did you do anything with the spark plug wires or the ignition sistem? With no spark your plugs will be wet when you pull them out. And its not gonna mess up the cylnder walls that fast. Cylnder wash is something that happens while a car is running and up to temp.. Not while its cranking over and cold.

Re:Turbo Installed. Wont Start. HELP!
 

Nothing in the ignition has been changed, double checked wires on both ends, and changed, checked plugs. I dont know. :\ But I'm really running outta time.

Re:Turbo Installed. Wont Start. HELP!
 

Sit a plug in the wire on top of the engine.. I assume your on your own.. sit in the car and make sure you can see the plug.. turn it over and see if it sparks.

The other option is your afc is not in right.. I had a stock gsr computer start and drive with 680cc injectors so I don't think that is your problem.

have you dried and cleaned the plugs yet?

Re:Turbo Installed. Wont Start. HELP!
 

Car should be dried out now. Going to check in a few. I dont beleive I wired my resistors wrong, because I dont see how I could have, and went over it quite a few times. I think I'm just running too rich honestly. Would setting the smc idle to as lean as it goes and trying to crank be hazardous? I'm going to do the plug trick right now and let ya know if I'm sparking. My Smc wiring is fine to my knowledge, everything is soldered good and intact.

Re:Turbo Installed. Wont Start. HELP!
 

You won't hurt anything just cranking it over..

Re:Turbo Installed. Wont Start. HELP!
 

you pull the fuel pump fuse and crank it over a few times so the oil pump starts pumping oil into the turbo.

Re:Turbo Installed. Wont Start. HELP!
 

Actually just thinking about it, I did retard my timing at the distributor? Could this lead to a starting problem? Didnt use a timing light, just pushed it back a few degrees.

Re:Turbo Installed. Wont Start. HELP!
 

thats easy enough to correct.. try it out?

Re:Turbo Installed. Wont Start. HELP!
 

I would say that could be the problem..

Re:Turbo Installed. Wont Start. HELP!
 

But wouldnt I want it retarded while boosting? I'll give that a try too.

Re:Turbo Installed. Wont Start. HELP!
 

You want it retarded a could degrees.. its easy to retard it a lot by just turning it.

Re:Turbo Installed. Wont Start. HELP!
 

Ok I really need urgent help on this. I made a fuel pump cut off switch and wired it up because I thought maybe it was giving too much fuel at prime time. So I advanced timing a bit, and pump original plugs in (i was running 2 steps colder). Car wouldnt start, gas, and a bit of oil drained from the car. (I added oil to cylinders). no oil leaks. So anyway I decided to turn the pump off for the ---- of it, and the bitch cranked and idled for about a minute I was scared of ------ ---- up so I cut it. My settings are all the way lean for idle -59%. Through 1,500. Anyway. It confuses me. I know the pump switch is wired right because in the off position it doesnt prime, otherwise it does, and I know the car started without the pump on.. WHAT SHOULD I DO?

Also once the car was idling, it flashed a CEL for like 2 milliseconds, and then came back on about 2 seconds later for about 2 seconds. A few seconds later I cut the car.

Re:Turbo Installed. Wont Start. HELP!
 

Well it sounds like you are definitely getting too much fuel.. @-50% it should not be rich.. the reason it ran with the pump off was it burned the exess fuel in the line.

Sounds to me like you have a problem with either the injectors or the smc. Do you have a spare pump you can use to test the injectors to see if they are leaking?

What plugs came in your car? are you running a 6 or 7 ngk now?

What ecu are you running? OBD1???

Re:Turbo Installed. Wont Start. HELP!
 

OBD2, I do have a seperate pump, but no transportation to go get it. Could it be that the car is burning off the fuel that flooded my engine from before? I fouled the plugs about 5 mins before I had it running this time with new plugs. Should I let it run out the gas, then try using a less lean setting and trying to start?

Re:Turbo Installed. Wont Start. HELP!
 

You mean more lean than 53%? Oh you said less lean.. you should be able to set it for about -40% and have it be very close.. Pull the plugs again.. Make sure they are dry.. With the plugs out and the fuel pump off turn the motor over a few times.. DON'T pour anything else down the cylnders.. Then after your sure the cylnders are clean put it all back together.. turn your pump on and set it for -40.. Turn it over.. if it doesn't start pretty quickly try holding the throttle wide open to let more air in.. Incase it is just too rich. If that works great.. if not keep trouble shooting. If you have to have the car running my next step would be put the stock injectors back in and unhook the wastegate rod.

Re:Turbo Installed. Wont Start. HELP!
 

Ok. Went to start it again with my settings at -47% let the pump prime, went to crank.. no go. So turned the pump off started right up. Smoking a bit, guessing thats from oil/etc. But running, now I have a constant CEL though. This is confusing.

Re:Turbo Installed. Wont Start. HELP!
 

Wait.. it keeps running with the fuel pump off? How long will it run like that? That is really, really weird.

Re:Turbo Installed. Wont Start. HELP!
 

Ran for like 3 minutes Id say running strong, rich on A/F gauge, idling at 1,500 firm. What could this be a cause of? The car only runs after the pump has primed, and the car is started with the pum off. SMC is blinking with the rpms, and CEL is on steady? Im stumped. Every few mins or so a hiccup is heard and a little bit of gas comes out, smells like burning oil. And its smoking.

Re:Turbo Installed. Wont Start. HELP!
 

Well remember you put oil in and it has had a ton of gas dumped in it.. I really don't understand how its still running with the fuel pump turned off.. Sorry I can't be more help but I have no idea about the smc and your car sounds like its doing some weird stuff.

Re:Turbo Installed. Wont Start. HELP!
 

Well thanks Todd youve been a big help so far. Appreciate it. If anyone has any other ideas heh shoot em by me. Because my car is posessed. lol. I guess I'll see how long itll run, most it could do is stop i guess.

Re:Turbo Installed. Wont Start. HELP!
 

Still running.. Stalled two times, cranked right back up afterwards with no fuel lol.

Re:Turbo Installed. Wont Start. HELP!
 

Whats up Blind? Glad to hear you got the car running and your turbo kit installed. Trouble shooting is a bitch huh? lol, it sounds to me like maybe the wires to the fuel pump cut off switch got reversed or switched somehow. I mean, it runs with the switch off... but won't run with it on... Thats my guess anyway. Let us know what happens man.

Re:Turbo Installed. Wont Start. HELP!
 

Well I'm pretty sure the cut off is fine. I honestly dont know whats going on, except maybe my fuel pump is too strong? Because I cant lean it out. And my smc is 99.999999% right.

Re:Turbo Installed. Wont Start. HELP!
 

Do you have an adjustable fuel pressure regulator? maybe your could turn the fuel pressure down with that.

Re:Turbo Installed. Wont Start. HELP!
 

stock fpr. What I dont get is that I've seen people with the walbro 255 pump working ok. Crazy ish.

Re:Turbo Installed. Wont Start. HELP!
 

Yeah, I don't get it either. The walbro pump is good for turbo setups. I'm confused. OBD2 sucks, so that would explain the check engine light. It senses too much fuel.

Re:Turbo Installed. Wont Start. HELP!
 

prime the turbo? i'm sure it would be fine if you just started the car and let it idle... its not like you're spinning the turbine to hell

Re:Turbo Installed. Wont Start. HELP!
 

the pump you are talking about is a second pump right?? you cant run wo a fuel pump. sounds like that pump is fucked up. try the bigger injectors and afc without the pump. if that works then mess with the pump. the bigger fuel pump shouldnt change the static fuel press, it should just be capable of a higher flow and pressue. thats how it should be set up. get a fuel pressure gauge and see what fuel press you are running w/and wo the 255 pump. (you can always return it at autozone)

Re:Turbo Installed. Wont Start. HELP!
 

Well I dont know what to tell you, but the power line is cut, and switched, and off. And the pump is not working heh. Also I gassed it a little, and its very slow when coming down off rpms.. What all could this be symptoms of?

Re:Turbo Installed. Wont Start. HELP!
 

mine didn't wash while i pulled the wires to prime, but when i cranked it to just pull it on the flatbed and then to get it off the flatbed and then to move it from the parking lot to the bay at the muffler shop without letting it warm up. rich settings and then the ecu running in cold mode (rich as well)=whole lotta fuel in left in the cylinders for it wash away the cylinders. and i'm sure of it because it wouldn't start when i went to pick it up and i did exactly what i told him to do and it fixed it. i also changed my oil because it had gas in it as well.

set your corrections so that your idle rpm 1k or 500rpm (if it has settings that low) is the equivalent of a 240cc inj. on safc it is -47 or -46.

Re:Turbo Installed. Wont Start. HELP!
 

Already have, didnt crank until the pump was turned off.

Re:Turbo Installed. Wont Start. HELP!
 

did you scan your code to see what it came on for? reset your timing to stock and use your stock pump. remove the fuel cutoff switch and reconnect as stock. this sounds way wierd. the only other thing i can think of is the resistors or smc is wired wrong. did you cross reference the wire colors you spliced into at the ecu using a shop manual?
