2006 Hummer 1 Alpha, batteries went dead, replaced batteries and it turns over but wont fire. anyone have any ideas? auto fuel shutoff??

 

fuel pump, fuse to the fuel pump? just taking a shot in the dark here

 

Thanks 2wheel. I feel its fuel related also, the hard part is the Hummer ran perfect until the lights were left on. We replaced the batteries and it cranks over fine, just wont fire. Possible computer security??? Older GM products had some type of system back then.The fuses checked out fine, Can not hear the fuel pump run when key is put in the run position. Since the battery went dead is there any reset procedure for the computer to recognize the fuel system?? thanks again.

 

I can also look into this for you with your VIN. Please feel free to contact me privately and keep me posted. Thank you.

just a shot here .....what about the pmd...i had the same problem one morning and 3 days later figured it out...hope this helps

 

tricia, how do I reply to you???

 

Tricia is a Troll she wont help you.

 

If the batteries went totally dead that can generate all types of weird electrical issues. You might need the ECM flashed. PM hummech, he can help answer your question.

 

Dealer is telling us that the ficm cracked and is allowing fuel to get into the electronics of the ficm. 700.00+ for the part. Anyone ever hear of these cracking?? I understand now that fuel flows through this unit to help keep it cool. Is it possible someone step on it?? This all happened when we sent it out to get painted. It ran perfect until we went to pick it up, the battery was dead then it wouldnt start. Been this long so far and still hasnt started, they are waiting for a new ficm.

 

I have not heard of that happening before.
