Hey guys i got a '01 f150 7700 series with the 5.4. Today i tried to replace the spark plaugs but i did not get too far. On #1 i removed the coil pack and accidentally knocked a bunch of crud down the shoot on top of the plug. I sucked out the junk with a vaccuum and replaced the coil pack. i figured i should clean the engine a bit before i cause a disaster. I put the pack back on and nothing. Everything in the truck turns on but there is no turn. Battery isnt the issue as i picked up a brand new one today. any help wwill be much obliged!!

Thanks,
Owen

 

When you cleaned the engine did you pressure wash the heck out of it ?

 

never got that far after i put the coil pack on it wouldnt start to get off the cement

 

Weird, the engine does or does not turn over ? If it does not crank check out the fat positive running to the starter - pretty common spot to fail.

 

no turn at all. i checked everything there is i letterally drove it onto the cement block, took off the coil pack, vaccumed the shoot out, then put the coil pack back on n now i got nothing

 

I would check all the connections going to and around the battery, especially the positive line to the starter (where it connects to the starter especially), makes sense to me because the battery is the only other place that was disturbed recently. I really do not think the coil pack and plug have much to do with a no crank situation.

 

ill give it a try when the light comes out tomm. idk what it could be cause when i try to crank it all my lights stay lit and dont dim a bit...who knows. thanks man!
