ECM PROBLEMS PLEASE HELP!?
Okay lets just get right to it. I was driving down the road yesterday i start to take a corner and my car dies. of course i try starting it again and no luck. so pull it back in the garage and i have spark. but no fuel pump. i just replaced the fuel pump. so its not that. but i go to check the codes and my service engine light isn't coming on. it doesn't even come on when i turn the key. what does that mean? wouldn't that mean its my ecm not getting power? is there fuses im not aware of? i checked my fuse box and there all fine. inline fuse? ecm is bad? can some one help??
i have a 1987 5.7 iroc Z. the fuel pump doesn't even turn on. and it doesn't even get power the fuel pump relay.
****UPDATE****
So i found out i keep blowing the fuse by the battery. Does anyone know what those wires go to? i jumped the circuit and the fuel pump relay buzzes.

Fuse Ruse
The fuse you mentioned powers the ECM and fuel pump.
That’s why the ECM is acting defective.
You have something drawing too much current in those circuits.
Remove the fuel pump relay, then see if the fuse by the battery still blows.
Report you findings.
