Is the security light on? Also, have you checked for fuel pump pressure? Who are "they" that told you? Was it a certified tech?

"They" are my brother in laws, and yes the light was on steady not blinking, at first we thought it was the fuel pump, but now he thinks it is the ecm, or icu. How would we know which one it is? Ive been without my car for 2 weeks im trying to help him out on his homework.

Not certified techs. One is a mechanic who seems to be stumped

If the security light is on, that is the problem and not the ecm. I hate to say it, but you need to have the computer scanned to identify where the problem is coming from. There are several things that could cause it.

Not until you have the computer scanned to identify where the problem is coming from. As far as the ECM, they aren't cheap so don't spend the money until we know for sure what is causing the problem.
