Not starting-weird problems..

Ok-2000 X with 7.3.

Well the weirdest thing is happening. I just finished installing my gauges and had started the truck a few times checking that everything was working as I put the truck more back together-everything worked fine. Got everything put in place and put my tools away. Went to back out of the shop and when I turned the key over the 'wait to start' light did not come on. I thought maybe I blew a bulb randomly so I just cranked it over after about 10 seconds and it started but immediately died. Tried again with same result and then wouldn't start at all.

Then found an undone plug on the back of the fuel filter for the fuel heater. By the way it was dangling it seemed like It had been that way for a while though, and was a real pain to get to snap back together-Still no start.

I ended up finding a blown fuse for one of the PCM functions under the dash-somehow I overlooked that one when I went through them the first time. Unfortunately my batteries that I was going to replace next week before I drive to CO to snowboard didn't want to live anymore. As I was trying different things I kept turning the key on which finally killed the things. I put in the new batteries though and I am still not getting it to start.

I loosened the cap for the fuel filter and turned the key and fuel sprayed out so I assume I am getting fuel. I have read a ton about problems with GPR's, but mine doesn't seem to have one-what do I check for this?

The only thing I can think of that might cause any of this is where I tapped into the ignition power, which was a 4 wire plug under the steering column-this is where the directions said to do it from Ken's Performance. I have checked it over though and all looks fine. I did undo the connection and wired it back to stock with no help.

I do have a friend coming soon with a code reader-hopefully it sheds some light on things!

Please help!!

Test all your fuses with a multimeter first. Just because they don't "look" blown doesn't mean they aren't.
Other than that wait for the results of your friend's code reader, provided he has a capable scan tool it should shed some light on things.

DTC P0381 is set when the PCM detects a malfunction in the glow plug indicator lamp circuit.
Possible causes:
Open/grounded circuit
Open WAIT TO START light
Open fuse

^ what he said.
That's why your WTS light didn't come on. It don't believe that would cause a no start situation, but it could be related.

Any idea what fuses might be good to check? The wait to start light is working fine, and cycles off normally.

Any other ideas?

Clear the codes and re-check.

Have you checked ALL of the fuses and diodes and relays under the hood and in the cab?

Just for some quick "shotgun" diagnostics.
Does the tach move when cranking?

Unplug the ICP sensor.

Tach moves when cranking. Cleared the codes and actually I didn't note that I am also getting a p1670 also (EF Feedback Signal Not Detected). I cleared the codes and that one came back-I think the 0381 code was from before I found the blown fuse and did not reappear when I retested for codes.

Is the fuel heater plugged in? Check fuse 30 under the dash with a DMM. If you want a pdf of all the fuse and relay locations PM me your email address

The fuel heater is now unplugged.

I found a good link with troubleshooting and it is telling me to check things on the IDM and PCM-what are those are where are they??

The PCM is the Power Control Module the "computer" or brain. It is located on the driver's side kick panel. In front of the emergency brake.

The IDM is kind of inside the driver's side fender. That's the Injector Driver Module, basically the brain for the injectors.

I wouldn't go there until you check the basic things, yet....

As Amiller said, you need to check EVERY fuse and relay before you go any further, or you're just shooting in the dark, spinning your wheels, pissin in the wind, etc.

Did you clear and recheck for codes?
What kind of scan tool is it?

Just got off the phone with a buddy that was a ford tech-he had me check a number of things..

I have checked every fuse-everything looks just fine. Checked oil level in the motor and HPOP. We unplugged the batteries to reset everything. Checked the CPS even though the tach is moving when cranking and it seems to be working fine. There is no smoke really coming out of the exhaust when cranking. I can hear the GPR cycling on and off so I am just assuming that is fine, plus its 50 degrees out so that shouldn't really matter.

The code reader is an actron CP9175. I did clear the codes and it only came back with the 1670 code.

This really sucks as I need to drive to CO on wed. to go snow boarding!

The pinpoints for 1670 are fairly complex. If you want a copy of them PM me your email address
