Need help.... with the 7.3

[STROKE THIS!!]

hey guys ive got a '99 superduty powerstroke standard.... has trouble starting and just runs like flat out sheet when its cold but once it warms up its fine..... glow plugs are bad but once it gets started it should run alright if thats just the problem i think.....injectors???? thanks for the help

Wouldn't explain the starting problem, but could your EBPV be causing the bad power when cold? I know mine sure does, and is pretty audible with exhaust and intake.

You need to fix the glow plug issue first before you try anything else. The glow plug relay (GPR) is a pretty common failure.

i mean when it does start id sounds like its gonna scatter lol but smoothes out when it gets warm

I agree, glowplugs first. With even a couple glowplugs out it will run like crap until it starts to warm up.

I agree. The glow plug issue needs to be addressed first. With even two glow plugs out it will run like crap until the engine starts to warm up.

i put newglow plugs in it but it didnt help..................... the gp relay is good too

do you hear the ebpv working, is there a loud whooshing, jet engine sound in the exhaust? It will cause a noticeable lack of power while cold.

o ya when i can hear tht noise..... it does it alot and if its in gear itll lag the motor down too?
