2007 chevi silverado wont turn on right away after i drive it

Asked by Jan 31, 2017 at 08:07 AM about the 2007 Chevrolet Silverado 1500 LT1 4WD

Question type: Maintenance & Repair

Hopefully I get a good answer
So when I drive my truck from one place to another
if I don't turn it off it's all good but if I turn it off it
won't start right away I would have to wait a couple
of hours for it to start again with no problem.....
We thought it has the fuel pump and had it
changed but nop.... it still did it... we took it to the
shop and they couldn't find anything wrong bc it
wouldn't do it right there crazy thing..
Heeeeeelllppp.....! It's so  frustrating

If this is the 4.3L engine, then this sounds like the Ignition Control Module. When they start to go, the engine heat will affect them so the the engine will not start when it's warmed up. Like you say, when it cools down it'll start. You can have that tested at an auto parts store.
