2000 7.3 Excursion. Truck ran fine on a 5 hour trip down to New Braunfels, Tx for family vacation. Pulled and to where we were going turn the truck off then what I had to do I came outside try to restart the truck for the next three days it would take 2 to 3 cranks before it was would start. Then on day number three tried six times and didn't start went to bed woke up the next morning and it took three cranks to start. drove it down to mechanic shop near me they have been troubleshooting and think it's an electrical issue the code is P1280; he said there were a couple other codes too and he would tell me what they were later but he never has. I took him a new CPS a new ICM and a new PCM, none of that fixed it. I am at my wits end here and really have to have my truck for work every day. Can someone who is good at this troubleshooting help me out? I am willing to pay to get this truck going again.

 

Pull the harness off the top of the ICP sensor and see if it is wet with oil. If so then the ICP is going south and needs to be replaced. Also look to see if the tin nut on the IPR is on snugly. They can loosen and allow the IPR to wiggle when it should be holding firm. If it is gone look around in the valley.

Save the old IDM and PCM, sounds like they are good spares.

 

Replaced ICP, CPM and the tin nut is secure on the IPR.

 

How cold has it been over there? Sounds like your having a hard time starting it when cold or on first start up of the day correct? Is so maybe your glow plug module went **** up.

 

90-102 degrees. The problem is constant whether it's running all day or first try in the morning. Ow it won't start at all.

 

Can anyone recommend a good 7.3 Diesel mechanic in DFW? The guy who has it now is just racking up the $$$$ with no results.

 

Need to hook up a scanner and see what it's doing.
As I remember this is what the truck needs to start:

10.5 volts while cranking
ICP needs to be a minimum of 500psi
150 rpms (I was off​ on this earlier)
fipw should be between 1&6ms if the other conditions are met.

If you don't have oil pressure or voltage it won't start.

 

Where in DFW are you?

 

If this is in TX, go on the local chapter there, there's lots of guys in TX that mitt help. What is your duty cycle and HPOP doing?

 

It might be helpful to find out what those other codes were, and did he clear the codes and check later to see which ones came back?

P1280 indicates a high pressure oil issue. That can stem from a bad ICP, IPR, shorted or chaffed wires on either one, bad connections to either the ICP or IPR, extended cranking with a no start, bad HPOP, or from a chip/tuner calling for more pressure than the truck can provide.

You or someone is going to have to get a scanner capable of reading live data on the truck to get more information as to what's going on. That used to cost hundreds of dollars. Now you can download a scanner named forscan, get the free live data capability, and go buy a cheap dongle that plugs into the OBDII port in the truck and you're good to go. I hear they sell the OBDII plug in thing at Walmart, but I've never looked for one there.

I know a really good Ford diesel mechanic out in Weatherford. I know of a decent one near downtown Dallas.

 

The truck is sitting in Keller, near Denton.

 

Please let me know the name of the diesel mechanics in Weatherford and Dallas. I'm needing all the help I can get.

 

Mad Matt's Diesel Performance is in Weatherford. He used to be a diesel tech at Ford before he went out on his own. Phone number appears to be (817) 441-1252 according to google. I know Matt and have his cell number, but don't want to give that out on the forum.

The other guy has a shop who's name changes often enough. Read into that what you will. He's just North of Downtown Dallas. I think his cell phone is the only one I've got as well, but I'll look and see if I can find the shop number.
