Motor finally installed but car wont start??? Z6/Y7 mini-me
 

K so I finally got the engine in and the new turbo setup all put in(after a year :S). After adding fluids I went ahead and cranked the motor w/ injector clips pulled to oil everything up, Oil PSI sitting at 20 while cranking. Went ahead and hooked up the clips but the engine just wont catch. Starts to putt and gulp w/ an ocasionally backfire about every 2 rotations. Stopped after about 5 mins of trying to start. Already i started to smell gas in the oil after i pulled the dipstick out....

Some background info on the build. Y7 block, Y7 pulley, scat rods, vitara pistons, Z6 head, Z6 dizzy, P28. All this in a OBD2 Civic(EJ8). Also getting a coolant temp sensor low/high voltage CEL(code 6). Had to extend the wires to reach the sensor on the z6 head. This is the least of my worries but any help on this too. Anyone have any ideas.

Re: Motor finally in but car wont start??? Possible dizzy prob???
 

I had the same problem after swapping my z6 in, Someone told me to check the ecu groung wires on the theormostat housing right behind the distributor and sure enough they were a little loost, tightened them up and it fired right up and ran perfect.

Re: Motor finally in but car wont start??? Possible dizzy prob???
 

Mine did the same thing, and my FPR wasn't tightened down tight enough. check for spark, it should've still fired up if you were getting fuel unless your dizzy is ----.

Re: Motor finally in but car wont start???
 

Well, I went ahead and rechecked and impoved(cleaned up) all the grounds and picked up a new/used z6 dizzy today. Also went ahead and put the factory 240cc injectors in and hooked up a stock p28 but car still wont run. Every wire is getting a spark, every injector is working, fuel psi holding at 40.... whats wrong? Seems like a timing issue? Ive recived so much mixed info on this and eveyone swears by what theyre telling me. Like I said, this is a Y7 block/pulley and a z6 head/gear. Cam and Crank line up perfect at TDC and dizzy rotor is on #1. ---- I feel like a GOD DAMN TARD!!! Any help? >:( :'(

Re: Motor finally in but car wont start???
 

Damn it, also just dawned on me that the gas in the tank is 11 months old. Its more then half full and I never added any kind of stabilizer to it. Would this matter?

Re: Motor finally in but car wont start???
 

I know the OBD2 heads have cam timing advanced by 4*. So maybe the timing is off.

Re: Motor finally in but car wont start???
 

Your gas may be ----

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

----, it'ld be an easy fix if its just a case of bad gas. ::) Doesnt make it suck any less if I have to drain half a tank of gas. What the ---- do i do w/ it? This ---- is driving me crazy!!! Im so close to getting my ---- rolling again!!!

Re: Motor finally in but car wont start???
 

Does this include the thermo housing? did the cel go away?

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

my civic sat for 2 years and ran perfectly fine on the same old gas. im sure thats not your problem. i think it sounds like there is something wrong with your fireing order

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

I'm shooting for that your timing is off. I say try putting the Y7 cam gear on the Z6 cam and reset the timing and try it. I wanna say the timing marks are different between the Y series and other sohc d series.

Re: Motor finally in but car wont start???
 

Still got the Code 6 CEL but that wouldnt stop the car from starting???

Firing order is correct, just rechecked.

thinking timing too. dont have a y7 gear to try w/ but wouldnt want to. wish I had a z6 pulley to try. The base timing is 12* on the Y and 16* on the Z. Folled some info online I found to set up the timing but think its bad.... Like I said pulley is at TDC and so is Cam but shouldnt I comp for the the timing diff. I know Im not the first to put a OBD1 head on a OBD2... Chime in fuckers. Obviously im :1 Im just waiting for the simple fix to eventually be revealed.

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

I had it the opposite as I had a y5 head on a Z6 shortblock. Jago is actually running the engine now. It's just another reason why I hate minime's though. I never set timing with the marks. I just toss something long down the combustion chamber and find TDC off of that. Always worked fine for me.

Have you send out my stuff yet?
Its been about a month already :S

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

Hey man, Fell behind on the cable bill and was w/ out the net for awhile and didnt have you addy. Back online and your stuff should be there by by this friday. Theres some extras in the package, hope you like. Sorry for the hotrex shipping, think its a new personal worst. :-\

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

Well I had a D15Z6 head on a Y8 block. That was a bitch and a half to get timing right. Yeah I think you need to adjust for the 4* difference in timing though.

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

damn mini me talk again

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

i would have to concur on the timing. ignition or cam, not sure. but you have fuel, air and spark. the only thing that is left to address is the timing.

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

hey bro try flipping the dizzy around

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

Good piece of advice right there. some people jam that dizzy key on backwards. Sounds to me like it's definatley in the spark. make sure you have the right dizzy for that head, and make sure your firing order is right. Honda firing orders are confusing

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

Well, Update.... Got off work early today so had time to work on the car. I ended getting a z6 crank pulley from a friend and out of curiosity I put the fucker on. Got everything lined up and tried starting it up again.... still nothing. So Im deff sure its not a timing prob. Even tried advancing and retarding the dizzy all the way and nothing. Car turns over......slowly and just gives me a random backfire. Thats also the thing, The car turns over slow as ----. Anyway a bad starter could be the issue??? @ this point Im ------- lost and looking for any solution. Its officially been a year since my car was on the streets and im getting antsy as ----. :'(

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

No the way you think is confusing. Right dizzy...nigga you know what the hell your talking about. Your the last person who should be giving advice. You were buying ---- anyone was telling you to buy for that fubar LS/CRX swap you gave up on.
If it's firing then the dist is fine. How's the battery cause if it's been sitting that long, I'm surprised it even cranked over. Slap some jumper cables on it and see what it's like. I still say it's your timing on that hodge podge engine. Find a y7 cam gear and toss it on it and then time it. You try just tossing the stock ecu in there. Being it's a y7 it's not gonna matter that it's vtec or not. I realize you have a stock bin but could be a bad burn or binpossibly. Maybe try tossing that ecu into another car and see if it works if possible.

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

when putting the Z6 dizzy on in an OBD2 car isn't there a few wires that need to be repinned or is it just a straight plug and play? make sure you didn't mix up the MAP and TPS plug when hooking everything back up. seen it done before and don't remember it throwing a code either.

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

changing out the crank pulley won't do anything except you might need a longer or shorter alt belt. The crank pulley has nothing to do with the engine's physical timing, only matters when the car is running and you're trying to set ignition timing. Maybe you're thinking about the timing gear on the crank?

I haven't read all your posts thoroughly, but have you fixed that code 6? A code 6 will usually dump way too much fuel, and if cold enough, won't let the car start due to the excess fuel.

Even if your physical timing was off by 2 teeth in either direction, it should start. This is considering if everything else is good.

Are you 100% positive your firing order is correct? What are you using to confirm that it's correct?

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

dayum aweful harsh from a guy that I actually bought stuff from. ::)

Re: Motor finally installed but car wont start??? Z6/Y7 mini-me
 

Dude I'm just saying and don't even pull that ---- on me. I always ripped on you dude before you bought stuff from me. So I was surprised when you bought something from me for all the hard times I gave you. Don't it's just HMT luv. Hell as long as the dist can be held onto the head and the shaft fits into the slot on the cam it'll work 99% of the time. DOHC ZC/A1's are the odd ball since they have the CAS mounted outside of the dist instead of internally like the rest of honda distributors. It just comes down to swapping connectors or repinning connectors.
