I have no idea what i killed in my truck.WILL NOT START. I get all kinds of check engine codes. How can you tell if the ECU is fried without 1. buying one and hoping its the problem and 2. Not bringing it to a dealer who wants you to pay out your tail pipe place. I replaced the mass air flow sensor and its still dead all fuses are good. I get code #s 21-22-31-41-51 . Buy the way this truck is for sale$600 firm, Engine is a re-man motor with 20k,new exaust,tires,starter,clutchmaster,front and rear windows custom bumpers,clutch and a new friggin mass air flow sensor. Any help would be nice

the engine turns over but does not fire is this correct? Check spark, Fuel and compression, timing, in that order, tell us what you get.

I do have spark, i dont believe i have fuel.Will almost fire up with ether, but even after turning over foa a minute plugs are not wet.

do you have fuel pressure to the fuel rail?

Nate

im not quite sure how to check. I fix the ecu problem but still have 2 codes, 24 and 51.24 is Air temp circut and 51 is TPS circut.
