Cool Need A little Help

Due to my present medical condition, I need to find a local FTE'r near Charleston to help me figure out what is wrong with my stroker. I cannot climb over it doing the test that needs to be done.

It still has the loss of power. Like it is not getting enough fuel. The mileage has dropped down into the low 10's. All filters and service work has been done with no better result. I was going to take it to Jody, but he has moved down to lower Georgia. That is just too far for me to drive with my medical problems.

Hey, just to get it fixed right I would pay someone.

Is there anybody out there around me that can give me a hand?

Give me until next week and I may be able to help. I will let you know dates/days this weekend. If someone else can get to you sooner that would be OK.

Paul I wish you were a bit closer.
Working 12's right now has me a little short on drive time.

I would be glad to help, but you would have to tell me what we need to do and check.

I am right at home on an IDI, but I would be lost on a Stroke.

Hammer and allen wrenches for tools, right?

Thanks Rod and Dave.

I just really don't know what it's problem is. There are no codes. It just does not have any power. Like the turbo is shutdown. But I can hear it spin up. It is like that it is not getting enough fuel. Almost floorboard at 80 on the interstate. It should not require that much. It acts like that old 302 I had in the F-150 4WD. Sick.

Any ideas would be great.

You getting any black smoke?
Anything with the turbo or boost leaks should have you rolling black smoke.

Fuel related, I would be totally lost on that side.
HPOP maybe?

No smoke, just no danged power. That 7.3 should sink yur but in the seat under full throttle. It just sags the springs. And the mileage is the pits. I just cannot figure it out.

That sounds like a fuel problem to me.

Steel HPX, that is the fuel high pressure crossover line isn't it?

Dave, that is the oil pressure stablizer line from the left head to the right head.

I am also leaning towards the fuel pump on the rail. It looks like it has been replaced before I got the truck. I am trying to locate a gauge that I can tap in the line to see what pressure the pump is pushing. I am also looking at a possible boost problem. The tach just swings too fast once it gets over about 2200 rpm. I think that the boost is suppost to start right after 1400. It has to be something between the two or maybe both.

OK, from my reading I new it had something to do with the fuel injection.

With the oil pressure even on both heads all the injectors should be firing the same.

I think I would look at fuel pressure to the injectors next.

On turbo engines, a boost problem usually shows as excessive black smoke.

The fact you have none tells me you boost is fine.
So if you have air, the only other thing you need is fuel.

If you have more power at higher RPM, that could still be tied to a weak fuel pump.
Not enough at low RPM, but closer to what you need at higher RPM since the pump is turning faster.

IDI logic on a Power Stroke....that might be dangerous.

Rod is probably hiding and taking notes on all this.

Well, it is really not more power, but it seems to spool up the RPMs a lot faster once it gets near 2200. I may have a boost leak at that internal turbo overboost valve. I am planning on tightening that thing down to see if it helps.

I am thinking that it is either the pump or that damn screen in the tank causing the problem. It did not start until the government went to this low sulphur fuel. I have heard some rumors from the dodge boys that it has messed with the cummings fuel tank pump clogging the screen. Maybe time to drop the tank and just do the hutch mod.

Dave, I still cannot figure it out. Yesterday, the damn thing started loping like a cammed gasser. It did it for about five minutes than quit. No Check Engine light and no code.

After that it ran fairly decent. Do you think the screen may be clogged in the tank?

Thats alright Rod. I am just nursing it along. I love that diesel, but now I think I should have kept the 85. I could fix most things on it with a hammer and a screwdriver. Just kidding.

Paul, looks like you are aware of why I like my 86.

The hammer and screwdriver tool kit worked on the 86 as well, but the IDI also requires a 5/8" wrench.

Most of the issues with ULSD for the IDI motor are lack of lubrication from the fuel.
I have noticed lower MPG.
Power numbers are down using the Butt O Meter dyno.

That is what I am feeling too. The Butt Meter and the Metal Pedal says something is wrong.
