thank yall! its drivin me crazy! truck runs so good when it starts haha. and its never parked on a hill... ok im kinda new at this as far as fixin stuff alone but if that bolt is leaking will it be visible or just kinda seepin to where i wont notice til I tighten it? sorry just tryin to figure it out ha

 

my stock lift pump was letting fuel bleed back and it was happening were the wires are rivited to the pump

 

the one on the back of the head you can see it if you can get a mirror back there to look at it or if you wipe your finger under it you will know if its leaking or not depending on whats on your finger afterwords

 

Is it possible to have hard starting if the grid heater is failing?
In the last couple of weeks my truck has had trouble starting only in the morning even though the block heater is plugged in all night. Then it doesnt have any more trouble starting for the rest of the day unless the the truck really gets cold again.
