96 psd questions

[CstoberDamm]

I have a 96 f250 with the 7.3 psd with almost 300k on the odometer. I just had 6 glow plugs, block heater & the thermostat replaced for a hard cold start/. lack of power 'til warmed up problem. Before they found 6 bad GP's the told me none of the injectors passed the buzz test & that was causing the problem.
From searching this forum I think my lack of power while cold was the EBP working. But on the way home from the shop I was pulling about 2000 lbs & I had no up hill power. The rpm's were higher than I had ever seen & I could hear the turbo whining but it lost 20 mph up the first hill I climbed. unfortunately I live in the Ozarks!
Does this sound like injectors or do I have a bad EBP valve?

here is the quick way, unplug the ebpv and see what happens. its the single red wire under the compressor side of the turbo

Thank you, I have tried that along with replacing the fuel filter & cleaning the fpr screen (which was very nasty). The truck starts up great & runs great until I encounter a hill. It will only pull 2000rpm @ 30 mph pedal to the floor up the biggest hill a few miles from the house. Other than the hard start issue the truck ran great up until the diesel shop replaced the parts I mentioned earlier. I'm stumped

Does it smoke heavy white when its chugging? Cause that would mean injector

[CstoberDamm]

No, I see nothing coming from the tailpipe & I don't hear anything funny, like a miss which I understand bad injectors will cause. If the shop hadn't told me the injectors had failed the buzz test I wouldn't suspect them. I find it hard to believe all 8 are bad & it runs as well as it does.

its possible, injectors will cause this and very hard starting if they are worn out and 300k is right around when they go bad.

Thanks, I guess I'll have the injectors tested by another shop to get it verified. Is installing injectors something a couple of mechanically inclined guys can tackle?

I finally got the truck to the ford dealer to have them hook up their scan tool. The map sensor had thrown several codes because it had been left unplugged when the glowplugs were replaced.

[kanuck15]

did that clear it up?

Yes, the truck ran great on the way home from the dealership. I should have taken it back to the first repair shop, but the truck wasn't running well enough to make the 40 mile trip back. Plus I figured they would just say " well we told you it needed injectors". I'm glad I didn't make that $3000.00 mistake!
