98JGC 5.2 Stumbles at cold start

The past few mornings my JGC takes a few cranks to start, when it starts it seems its not firing on all 8 for about two seconds then it runs fine.Its had a Recent tune-up and starts fine the rest of the day. Any ideas? Thanks, JK

What has your weather been like?

Moisture around the ignition system perhaps....

billy ray did pass the time by typing:

Or fuel leak-down putting air in the injector rail. That can be just about anthing from the check valve at the fuel pump to the regulator. Including leaking injectors.

JK, try this. Turn the key on, wait a few seconds, turn it off, then turn it on, wait a few seconds, then start. That basically runs the pump a couple times. If it starts well after that then your problem was leak-down.

It's been very wet, I live near Seattle.I filled up at a 76 station I've never used before right before the problem started, bad gas maybe? I will cycle the pump a few times and see what happens....Thanks
