Looking to buy this truck but...

[Galaxie]

Hello everyone! I am was messing with a 99 stick 7.3 today (late build 6.99) having some issues….

1. P1280 = injector control preasure circuit low
2. P0344 = camshaft position
3. P1211 = ???
So here is the deal. Started her up and let her warm up for about 10 minutes. Started perfectly. Has been sitting for about 4 months… went up the road, all is good. I noticed the check engine light and battery light came on. Then bam, started running very rough. So, I pulled over, shut down and restarted. Ran smooth again.. pulled out in 2nd and hammered it, black smoke and a ton of power. Nailed all gears, perfect….. slow down, running so rough, the shifter was moving like mad!!!! The motor was bouncing around from rough idle that bad! After we get back it is idling perfectly….then just dies. Get back in start it up, idle is perfect for 5 minutes then dead. Starts back up perfectly right away.

I want to buy this truck..... does anyone know what i am dealing with off hand here? It drives, shifts and stops well... Just wish she ran well!

Thoughts?

P1211{2}
ICP Pressure Is Above/Below Desired, Faulty IPR Valve

P1211{1}{3}
ICP Pressure Uncontrollable, Pressure Above/Below Desired

Sounds like a bad ICP and/or IPR. I would throw a new CPS in it too.

Still a good deal for what you said you would pick that truk up for.... test the ICP by unplugging git an then starting/running it and see if that fixes it.

What are you using for a scanner?

How much are they askin? It don't sound like nothin serious you gotta deal with. they get a little fineky sometimes when little things are wrong.

Thanks guys. SCT 3. Now that i think about it, the scanner did say ICP. When I posted this, I just came back from Pizza/picher night. Needless to say, I was full and a little drunk. Silly 6.0 guy trashing up the 7.3 theads! haha

Anyway HAMMERED body. 99.5 regular cab 4x2 again driver really good besides the crazy serges and missining. about 2,000.

With these sensors, how much do yout think I have to invest in time and cash flow? I do all work myself.

For a NEW ICP, NEW IPR complete assembly, and NEW CPS, you're looking at proly 400 bucks MAXIMUM, shipped, taxed, and all the best parts. Then *maybe* 3 hours of work at a beer drinkin pace

I'd jump all over it.

Ok..... I am on it. If he takes my offer I will have another diesel.

There a chip or program on it?

It definitely needs a CPS

Dave, I have driven a lot of 7.3. Friends trucks, trucks at my old job. Sticks and Autos. This one feels tuned - it pulled more than just about any stock 7.3 I have ever been in. However, origonal owner. He said all he has done is fluilds, brakes and tires. This is a stright up work truck - the guy didnt even know what I was doing when I pulled out the SCT to get codes. If it is tuned, someone would have had to sneak in and tune it. lol

So, according to him, no, not tuned.

If your ICP sensor has failed, oil in the plug will affect the readings, which could trigger more injection pressure at times, giving it a little snappy feel to it and a little bit of a lope possibly.
