Hey guys I need some help.
I was driving my monte carlo ss 3800 v6 auto about a month ago and a deer jumped out in front of me but luckily i wasnt going very fast and it only busted my headlight and never even blew the bulb. So i drove it home. Got up next morning and it wont crank over. I have dash lights, interior, replaced headlight so they still work, and everything seems fine til you crank it and it does nothing
I have no fire to the starter, fuel pump, ignition module, and nothing at ALDL connector? Replaced ignition switch, texted BCM and it's fine and texted starter and it's fine as well. Only thing I haven't checked is the ECM. What do u guys think is wrong?

 

Not a single response?
come on guys give me some TIPS. I've tried everything but buying a new ECM and hate to drop a couple hundred bucks on one and then have to get it programmed at the dealer for another 100 bucks just to still have the same problem.
I have no fire at the ALDL connector and no fire at the fuel pump? Any ideas?

 

Thats the hard part with electrical issues - trying to diagnose remotely without actually taking a single reading in person is very difficult. Its more convoluted in a situation like this where the potential cause and the problem are seemingly completely unrelated.

I'd break out the wire diagram and step through every connection of every circuit to follow from where you have power to where you lose it (or ground). Clearly you have power at the battery, and have none at the fuel pump. Id step through every connection in between with the meter until you find out exactly where it loses it.
