2004 4.3 hard to start after sitting for a couple of days
 

truck starts fine every day. Let it sit a couple of days and doesn't want to start. I can hear the pump prime but no start. Turn key on several times to prime maybe loosing prime, but have fuel at pressure tap. Pull plugs they are dry and getting fire to plugs. Pull top off of throttle body put hand over top and crank the motor. started to spit n sputter and started up. This happened before and the crank position sensor was bad. Now it starts and runs fine now.wierd! This has happened a couple of times on me. Any suggestions ?tks

2 things I have run across.

1. Check/change fuel filter. Folks tend to forget about them since the V* models are in the tanks.

2. How old is the distributor wires/cap/rotor. Mine had spark, but super weak.

A friend of mine had issues with his 4.3 in an S10 and his ended up being the intake spider thing, however being urs is 2004 you should already have the newer design spider.

Bill,cap,wires& plugs new. filter been changed. Is there a way to check the spider setup? Thinking moisture in cap? Cap is about a year old. Check that soon.coody
