just fixed my car, turns out the problem was the ecu , it was just replaced with a new one. now there is a diffrent problem(this car seems to have a multitude of problems), Everything ran fine but the car was shut off and a couple hours later, restarted, but all it did was

Crank-->Start-->Ugly horrible idle-->No check engine light-->3 seconds later---->dies (there is a strong gas smell comming out the exaust pipe those 3 seconds it's on)

I've been researching to the point where I started having dreams about researching, this is what I've narrowed it down too.

-It could be the fuel pump(but a bad fuel pump means it wont start, right?)

-It could be the fuel pump is on but isnt recieving enough power from the fuel pump relay, while it's on(should I just buy and change the relay? If the fuel pump relay is bad wouldnt there be a check engine light or not?)

-It could be the ECI or ECU fuse in the front blown due to a huge sub and a heavy amp sucking speaker system was put in, after a day of that sub the car had this problem, can that cause a eci or ecu fuse to blow?)(how would I even check? Can I just look at it?)

We thought it was the ecu again but all 3 ecu's have the same problem, no caps are leaking on 2 of them , they are in perfect conditions, cant be MAF because there is no check engine light(but it does have the same symptoms)

sigh, has anyone seen anything similar?

 

anyone?

 

I just took my car today to AAMCO for a FREE Diagnostic Test.
Results: Code 31 - Knock Sensor Circuit Problem & Code 14 - Throttle Position Sensor Adjustment

Don't know what this means exactly, but will be taking it in to be repaired in the morning.
