03 gm 3.8 crank no start. was created by Bricks224
Hello. I have an 03 chevy monte carlo with a crank no start. This car has been beating me up for 8 months. I just refuse to tow it to a dealer. Anyway. I believe I have good spark and injector pulse. I need to run a noid light on it yet. Resistance was checked on all injectors but one. Coils seen good. Had the electronic control that hold the 3 coil checked. Ok. Replaced fuel regulator and fuel filter and outer ignition switch. Showing 50 for fuel pressure. Security light is on but not flashing. Read all codes only had oil pressure circuit code. Replaced sensor. My code reader would not read bcm codes so I bought one that did. Cleared all codes only code that cam w back was left door voltage high. Door locks blow fuse overnight. Factory amp in back is completely unplugged. What am I missing? Bad BCM of bad fuel pump. Spark plugs are dry.???

I think you answered your own question :)
Need to verify injector control with a noid light or test light, and verify the presence of spark out of the ignition coil.
