I have this very frustrating cold start issue.

When the truck is cold or hasnt ran for over a couple hours, I have to crank it for ten seconds, then pause...then crank(it tries to start)about 5-10 times more till it finally coughs to life. If it runs for a minute and I turn it off it fires up instantly again when I try.

Its getting very frustrating.

No vacuum leaks
new fuel pump(did it with the old one too)
changed the cold start time switch
changed the cold start injector
what other sensors/places should I be checking?!?

Thanks guys

this is not your typical cold start issue...

 

Had a similar problem.I'm not mechanical at all but here are a few things I've read on the internet after searching for months.Thermo temp sensor,next to the CSI switch..banjo bolt..fuel rail leak,fuel damper below the t-stat housing.Finally just had a fellow bypass the CSI with a toggle switch,starts every time.Not the correct way but it works.
