Truck Wont start
It will not start... ran fine last night. puffs white smoke.... tach shows rpms, Maxi fuse 22 is good all fuses are. The only thing that I can see is the resistor I put in between the PCM power and ground for the EBVP is burnt up... I will take that out and see if it will fire, but it should shouldn't it?
It also has a CEL but I have not been able to check it yet. I took off the fuel bowl heater too, still no start. what else can i check easily before I go out and buy a code reader, (mine stopped working).
HELP!

If it's puffing white smoke it's getting fuel. My guess is the glow plugs aren't getting hot. Try crossing the GP selenoid with a screwdriver for about 30 seconds or so. Do you get a WTS light when you turn the key on? If so, how long?

Try plugging in the block heater for an hour and see if it fires. You may have a bad GPR - take a pair of insulated needle nose pliers and jump the two large terminals on the GPR for a minute and then crank it over and see if it starts. If it does, bad GPR. Also test for resistance on each glow plug - if 3 or 4 are bad it gets very hard for the truck to start in the cold.

Glow plugs are all new.... within two months all motorcrafts...
I can hear the GPR clicking, but I will try that too....
And the resistor is inbetween the PCM wiring for the EBPV because with it unplugged it would set a CEL, so I put a BIG 10 OHM resistor inbetween those two that confused the computer into thinking that the EBPV was still hooked up.

Still gotta wonder why the resistor burned up. It goes directly to the PCM...may be really bad if it shorted out some how.
BTW: I unplugged mine and didn't get a CEL...maybe you mean the EBP Sensor.

I have a California truck, so it sets P0475 when the EBPV is unplugged, so I put the resistor in just like others have to get rid of the CEL... lets hope its the GPR... if not i might need a whole new engine harness...
