Exhaust smells like raw diesel! HELP!!!

[mfdboy911]

Hi i have a 2000 7.3 F350 i replaced all the injectors and glow plugs about 7 months ago and just 2 days ago it started smoking really bad when i turn it on in the morning. The smoke is white and i live in Los Angeles, Ca. so i know cold start is not a issue. I also noticed that the smoke does go away a few minutes later but i do smell a strong somewhat clearish raw diesel smell that i did not smell before. Could my truck be running rich and that be causing the white smoke at startup in the morning? The wait to start light does stay lit for about 15 seconds in the morning. Thank you for your help guys!

i looked at a truck that was doing this same thing and been having trouble finding answers but it almost has to be glow plug related. did you replace the glow plug relay also? those like to go bad to.

Hi thanks for the response i did not change the relay but back when i did the job i tested it and it was working properly i will definately check it tomorrow morning and get back on here with the results!

ya if the glow plugs are all new i would think its the relay or pcm not telling the plugs themselves to come on.

Could it still be the relay if my "wait to start light" still comes on for about 15 secs?

im not sure on that one really

Just checked oil dipstick and I had to add 2 quarts! It still smoked a bit after I filled it and started it. Could have the low oil caused the white smoke? I'm going to try starting it tonight once the engine cools down to see if the white smoke continues.

may be gp wiring harness, those are famous for bein crappy, might wait til u hear the glowplugs click off before startin it, it'll still get cool at nite and have trouble startin and smoke. as far as oil i'd say it is okay, i think as long as they have good oil pressure they're okay, mines been lower than that before and it seems to be fine

I have no trouble starting at all. Just white smoke is the problem.

if it goes away after it fires up then its prolly okay
