very odd problem
 

here is the setup
93 civic ex
p28 that came stock in the car and has been running chipped for the past 3 years
ostrich 2.0
crome free

i drove the car to work and back yesterday on this .bin i am using now. the car was sitting idleing just fine as we were loading up to get a good street tune on the car. nobody touched anything and out of nowhere the car dies and the CEL comes on. my first thought was that the ostrich got pulled out of the socket. i checked it out and it was fine. just to be sure i pulled it out and put it back in and i also tried reloading the .bin to the ostrich. same problem. when i turn the key on none of the dash lights come on except the CEL and the fuel pump doesnt run. hoping that maybe just my ostrich died( should be a warranty on it right?) i burned a chip with the same .bin and it does the same thing. i looked at all of the fuses under the hood and they are fine. i also looked over my ecu for anything that might have shorted or burned up but there are no signs of a problem.

hopefully i can either get a hold of another chipped p28 to try or try mine in another car. maybe i will try cutting J1 and see what happens. it wont run due to my 650cc injectors but at least maybe the pump will run and it will sputter a little bit so i can narrow down the problem

Re: very odd problem
 

what about your main relay?

Re: very odd problem
 

would that also cut ignition? i shot some starting fluid in there and got nothing.

i have never acctually had the infamous main relay problem out of like 10 hondas i have owned

Re: very odd problem
 

i got out my trusty test light and there is good 12v going to the main relay but nothing when i turn the key on. does the ecu send the signal for the relay to come on? if so i am pretty sure my ecu took a ----. i am starting to think i should have been using a resistor box with my injectors.

Re: very odd problem
 

Check your grounds????? You can get manuals at www.hondatech.info. Get the etm for your car and go at it. You only have to use a resister box if you are using low impedance injectors. You should still get spark if that was the case.

Re: very odd problem
 

the injectors had like 10 ohms and i know i dont have spark or fuel. i have the helms manual in pdf. its just a pain in the ass to look through

Re: very odd problem
 

What kind of car I can try to help?

Re: very odd problem
 

check your ecu fuse? if you didnt use a resistor i thnk your ecu may be lil fucked up but its fixable

Re: very odd problem
 

car is a 93ex. all the info is in the first post.


what gets messed up if you dont use a resistor box when you should. i chipped the ecu myself, im sure i could replace bad parts. i am really leaning towards that problem. the car has run probably a total of 1 hour with those injectors in and then it died. i am really leaning towards that

Re: very odd problem
 

If your 650's are 10-12 ohms they are high imp. and dont need a resistor box.

Re: very odd problem
 

that's what I thought, but the only change to my setup are those injectors and removing the resistor box. One thing that worries me is that my ecu was open on both sides and might have touched a ground and shorted, but there is no sign of anything arcing or getting hot

Re: very odd problem
 

The ecu grounds the injectors thru itself. Id make sure you dont have excessive resistance to ground from the ecu. .5 ohms is enough to screw with your injectors.

What is the CEL? what code is it throwing?

Re: very odd problem
 

I tried checking it and it won't blink. I just had a thought that maybe the ecu ground on the thermostat housing didn't get tightened down and maybe it vibrated loose. I will check that when I get home from work tonight.

Re: very odd problem
 

are you still getting power and switched ground to the injectors? kinda sounds like what happened when my coil ---- the bed. just died when it was idling right before i tuned

Re: very odd problem
 

i havent checked the injectors, but i know the fuel pump isnt running and i know there is no power going to the main relay when i turn the key on

Re: very odd problem
 

i had this same problem the other day putting in xenocron fuel pump...i pulled a dumb ass move and my cel was staying on and nothing else was happening...i checked the main relay per the honda manual, everything checked out....then i checked the fuse next to the srs fuse (two fuses that stick out on the top right side of the fuse box under dash) and it was blow...put in a new one, and everything went back to normal...

also check the ecu fuse under the hood, blew that once and had very similar problem


:y

Re: very odd problem
 

all of the fuses under the hood are good. all of the ones i could easily see i pulled out and checked. i am going to check the ones next to the srs right now though.

i learned a long time ago working at a nissan dealership, when you are having a weird problem, check every fuse. when you fix a cruise control problem by replaceing a windsheild wiper fuse it will make that stick. that was a long time ago and its easy to forget those things when its your own car

Re: very odd problem
 

you sir are the ----. problem solved

werd...glad to help >:D
