New to the board folks and looking for some advise. I have 00 7.3l that's having problems starting when ~cold. First of all when I say cold it's not cold outside, 50-70 degrees. I replaced both batteries, new alt, new battery cables, 4 new glow plugs (drivers side). I checked the GPR and it's good.
Here's what happing. I let it sit for 2 days and when I turned the key to Aux. the "wait to start" light comes on as it's suppose to. I noticed the battery cluster gauge goes to ~13 the drops to ~10. When the "wait to start" light goes off I try to start it and it seems like a large draw it taking from the batterys. Very sluggish. With the new equipment this thing should fire right up right?
Now, I plugged it in for 2 days (70 degrees outside) and tried it last night and when turned to Aux. position the battery cluster went to ~13 and didn't drop. "Wait to start light" turned off and she fired up.
My question is why does it fire up once heated and not at a "cold" start. Also, it cranks over fine when I drive it around town.. long as it's warm.
I like doing most repairs myself because I learn from it and can share my experiences with others but I'm far from being a mechanic on diesels. Also, it's easier on the pocketbook.
What am I missing here? I've read things about the PCM, but I have a wait to start light and it seems to be working fine.
My truck has 150k on it.
Any help will be greatly appreciated
