ocasionally does'nt want to start?
I have a 99 silverodo, with 126K on it. Very good about regular matinence on it. Sometimes I go to start it & it cranks but will not fire. Hot or cold & sometimes I can just turn it off go in a place come out & bam it won't start. I thought it was the fuel pump so I bought one. Did the same problem a week later, that was a costly mistake. It has'nt thrown any codes. Any Ideas???? Maybe a crank sensor going in & out? This only happens every once & awhile, but very frustraighting. And the truck usually starts after a minute or so.

Is this a V6 or V8. I remember when I had my 2000 silverado V6 it would do the same thing. I thought it was the fuel pump also but I checked the pressure and it was fine. It ended up being the ignition module beside the coil pack. I replaced it and never had anymore problems out of it.

If it's a 99+ then start the truck, turn it off, pull the vacuum line that goes to the fuel regulator on the rail, if it has fuel dripping out of the line the reg. needs to be replaced. This is the most common problem with these trucks.
