Heres the problem ... My buddies truck is 1998 ck1500 5.7 liter 4x4

It doesn't start. Runs for a few seconds then dies.
Replaced fule pump, fule filter, spark plugs, wires, dis cap, starter and still not running.
It's fule realted, she gets the fule fires for ownly a few seconds then dies.

Aany advice

 

passkey security sucks

 

May or may not be a passkey issue. I had issue with my 96, start run, start die, or no start. This was an issue with the ecm not reading fuel enable signal.
