01 Tahoe 5.3

[Harley1]

Hope someone has heard of the following problem and has a fix. I replaced the AC Delco battery (pos. post broke off) the other day, now the engine runs for about 10 seconds and then dies. The only time the security light is on is when the key is not in the ignition (normal). Is there a reset button for the fuel pump?

 

Thanks in advance for any help with this problem.

Quick update...........I pulled the relay for the fuel pump, switched it with the horn relay (same size relay), the engine roared to life. I am getting some engine stumble and do think that it must be that the air box is not installed. I'll install the air box and hope that the idle smoothes out.

Is the MAF sensor installed? Chances are that by installing the air box the MAF sensor will get a correct reading and the engine will smooth out.
