You got this from IA? I know he did the fuel pump ecu bypass, so that rules that out, did you try the FPR that he said was a probable issue?

Push4Tyme

im breaking it down tomorrow to see if that is the fix (fpr)..

i have talked to a few techs and they seem to think otherwise.. possibly the inj arent firing, but then again the car has no cels or dtcs

and yes this be an ia car

if you give me the lip i may drive down there and try to help you out a little bit....

Push4Tyme

haha the lip is slightly broken... im planning on putting it back on...

and i talked to the original owner of the car and he said hey doesnt think its a fuel problem... maybe a bad ecu

crank the motor...then pull the plugs.
are they wet?

if it's wet then you don't have spark...(assuming the gas is good).
if it's dry then you have an injector issue.

My mom's LS400 had the same problem. It was a bad ECU.

Push4Tyme

Push4Tyme

the ignitor might be bad, not giving off any spark. check that out.

Got it rebuilt for 100 but it didn't fix it...so we bought a used one on ebay for $250



pm aliga, he might have one.

Push4Tyme

hate to pick ur brain, but what did the car do exactly when the ecu, "went out" or, "was going," out?

Push4Tyme

changed it man still nothing

Good Afternoon,
Our 91 SC 400 would only start when cold but wouldn't start after the 5 minute drive to work until the next day...it ended up being a fuel pump.
