Sometimes it will not start... Any ideas??
Sorry if this is in the wrong forum, but I figured it belongs here.
I've searched the forums and I can't seem to find a thread with a similar problem I'm currently having.
I have 99 GMC Jimmy 4.3L 2WD SLE trim.
The problem I'm having is that sometimes the SUV would try to start and then just quit. I engine turns, so it's not the starter. The spark plugs go, so I know it cannot be that, pluse I don't get any misfire codes. Sometimes this happens to me when its a cold start (so far this happens more often) or when I start the SUV up shortly after I turned it off, when it's been off no more than 3 minutes or so.
I pump the gas pedal and that seems to help it, but I'm not 100% sure that actually as it usually starts the second or third time I turn the keys with or without pressing the gas pedal.
Could I be experiencing the early signs of a failing pump? Clogged/faulty injectors?
I'm going to start taking things apart this weekend when I have more time. The problem is very random, but has happened more often than before recently.
