Was driving down the road and engine just stopped? engine light came on after engine stoped and I had oil presure. Tryed to restart and the tac. worked but oil guage didn't. someone borrowed my scaner so I don't have any codes. Any ideas?

 

If you don't have any oil psi, your low pressure pump may have died. If the high pressure oil pump reservoir goes empty, your injectors cannot fire. On a high note, at least if your lpop dies on you, the motor shuts off before it does damage.

Two things come to mind when a truck just shuts off. First is a cam sensor. But you said the tach was reading. Next is the fuel bowl heater element. The little puck in the bottom of your fuel bowl. If it comes loose and touches the fuel bowl, it will shut the truck off.

When you try to start it, does the wait to start light come on? If not, check that heater element. It has a bad rep for coming loose from the 3 soldier joints that hold it.

 

Fuse 22 under the hood gets blown from the heater element, check it

 

Wait to start light is working and their was a fuse blown cann't remeber which one do know it was 30anp. I did take fuel filter out and it was all black filmed up like it was plugged

 

Then you need to definately check your fuel pressure regulator screen.

 

Is the fuel pressure screen in the fuel bowl

 

yes sir take the filter out and look inside the fuel bowl on the drive side and you will see a little hole take a Q-tip cut the cotton off and clean the FPR screen

 

Cleaned fuel bowl and the fpr screen and found that the fuel heater elment wire was broke. thanks for all you help, Will go to ford and get a new one and see if that fixes it . Will let you know.

 

just unhook it from the side of the fuel bowl and change the fuse if needed if that is the problem then it should fire up

 

Put new fuel heater element in and scaned it with on codes coming up, fuss was 17 or 18 can remeber right now. still won't start. tac.does work but only reads a couple hundred rpms and oil presure doesn't come up,I did fill the front res. up. picking up new cps tommarrow and going to try that. I just hope it's not the LPOP, I can't remember, is the lpop in the pan?

 

LPOP is behind the harmonic balancer ,outside of the front cover

 

OK, put new CPS in, new FHE in, and no codes, tac. works, WTS is working. No oil presure, so I filled top resover and removed oil line to the injectors and turned over and oil did come out so HPOP is working, renistalled oil line and refilled resovor and left plug off and turned engine over and the oil level when't down. So that pionts the the LPOP. Does that sound wright or am I going in the wrong direction? And I'm asuming that the oil presure sending unit is on top of the HPOP housing?

 

Remove the oil filter & see if anything falls out from above it ...

 

Allready changed oil and filter and everythang looked good. Any other opions?
