I thought I had this resolved, anyway after replacing the glow plug as I stated in my last post I was using this vehicle with no problems...I have not started it in about 2 weeks... went to start it yesterday and it just cranks no start with some white smoke coming out in the back??? any takers.??

 

Do you hear your lift pump running when you turn the key to the ON position?

 

I swapped out the lift pump a month ago...its working fine...It did start yesterday, it took about 8 to 10 cranks of the motor...

 

Make sure the lift pump is running anyways... I've seen a new lift pump fail in the first 2 weeks before (defect) -- make sure it is running, even if it is a relatively new part.
Or, it could be "turned off" for some other reason (e.g. faulty oil pressure sender)
