Fueling Issue?

[stingragtiger]

2005 silverado 1500 crewcab z71 5.3 died this morning while idling waiting to drop off my son at daycare. Wouldn't start backup. it will crank over but no start. took him inside, 5-10min later come back and try again. same thing,shut key off and tried again and it started. any ideas? runs fine other wise. sometimes i've noticed the key switch seems to have a delay before it will turn over, but it might just be me. starts fine all the rest of the time. new battery installed about 2 months ago.

sounds like a possible security issue.

finally threw a crankshaft position sensor code. it would only act up when i got back in truck from dropping my son off at daycare. weird. I let it idle for 1.5 hrs two different times and it would run just fine. Fuel pump, switch, nope. any way still cheaper than the dealer repairing it.

ps, if it happens to you watch the rpm's when you are trying to crank. will not register.
