I'm having trouble with my truck starting after its been running for awhile and then I shut it off.... I have to let it sit for a few min. before I can crank it again and it will start. I was driving down the road and it just died on me the other day that's what started all this... The fuel pump and filter was already replaced and I just replaced the cam and crank sensors ... but its still acting up...... I'm not sure where to turn next... anyone have any suggestions?

oh and no check engine light ..... I have a scan tool and checked for soft codes but nothing.

 

once it is running...how does it run?

when you get this "no start situation"...does turn over or not?

 

When its running it runs great no missing or sputtering .......yes its turning over ....if I let it sit for awhile it will start up .....then run great but if I turn it off then no start just crank and crank ...

 

have you tried to swap the relays for the ignition and or fuel?

If you try to start it & doesn't ....if you cycle the key on and off (with engaging the starter) a few times will fire up?

 

I've tried swapping relays for the fuel pump and then actually bought a new relay that didn't fix it ...... I thought maybe the starter relay but it doesn't matter how many times I try to start it or cycle the key it wont start unless I let it sit for about 15 to 20 mins. also tested the fuel pressure from the fuel rail and it has good pressure and doesn't leak down......

 

does the anti theift light flash during this no start situation? well at a faster rate than normal anyway
