bad cold starts

[crewcabhallin]

I have a 1995 crew cab 350 with a 7.3. its has bad cold starts with lots of blue smoke slight skip in the morning, good compression also has very poor fuel mileage no check engine light. please help me

[who fan]

Sounds like a normal cold diesel to me. Diesels don`t like being cold. Common cold weather start up.

Does it have a block heater & if so do you plug it in at night? If not get one & use it. This should help it not be so grouchy on those cold mornings.

as for poor fuel milage, change the fuel filter and run some power service through it. otherwise, as for the cold starting, i own 2 diesels, a 2000 powerstroke, and a 85 6.2 detroit. They both seem to start off about 4 cylenders when first starting, but if you have original glow-plugs, I would replace those along with a new glow-plug relay. You have to take off the valve covers to get to the glow-plugs, so make a day of it.

i got the problem the cat was cloged and their was a lose injector. Before i had it fix i used 2 put the gas pedal to the floor an it would go! But when i put the pedal to the floor now i get a 100ft slap of rubber behind the truck

What is a loose injector, a leaking injector?

[ModMech]

Well it surely was NOT a "loose" injector, if the injector hold-down bolts are even the slightest bit loose, they WILL leak oil into the fuel, and you will need new injector o-rings to fix it.

Yes, a clogged cat will do this.

Detroit NEVER EVER made any engines for light duty vehicles for GM or anyone else. The Olds 5.7L, and GM 6.2L/6.5L engines were NOT made or engineered by "Detroit Diesel", but by GM of which Detroit Diesel WAS a subsidiary.
