My 99 maxima doesnt start, (it will with ether) they're saying its the computer or the anti theft device? How do I know which one it is? At first we thought it was the fuel pump.I would gladly accept any and all advice you could give me

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.

Should I get a new icu then? Are they hard to come by? And what am I looking at to spend.I really appreciate your answers. Could you please enlighten me on the several things that can cause it?
