Bad Injector?

[99red7.3]

Hey guys i got a 99 psd. It runs hard when i first start it but after it warms up it runs fine or if i plug it in for about 2 hours it does fine to. So i thought i need to replace the glow plugs so i did and also replaced the glow plug relay and still i have the same problem could this be a bad injector or injectors? Thanks for the help Evan

does it do it without the 10K mod in? do you run any fuel system cleaner (i.e seafoam through your fuel bowl), or biodiesel mix? that's about the limit of my "expertise". Maybe get it buzz tested along with a cylinder contribution test?

yes it does it without the 10 k mod i just put that in and mines on a switch anyways. but i have ran seafoam throught the truck but just put it in the tank didnt put it straight to the fuel bowls.

Ever run any ful injector cleaner through it? Could just be a dirty injector. Not quite sure, but it could possibly injector o-rings bad. How many miles on the truck?

Yea i just replaced the fuel filter this weekend and dumped a bottle of seamfoam in the tank still hasnt fixed the problem. and its getting to where its only wanting to start when i spray ether in the air filter until its to running temp then it runs and starts fine but its got around 217xxx miles

mine is doing the same thing only worse.. check your fuel pressure reg, do your injectors make alot of noise? mine are loud, way louder than my buddys 7.3 so im going to be changing out injectors next week..
