Not sure what kind of oil to put in my 1988 f350 diesal?

Use a funnel and put in the transmission oil through the transmission dipstick tube. Don't put too much. Insert transmission oil in increments just to be sure.

10W30 weight.

Inside the tank there is a plastic housing. if you look at bottem of this you can see little tabs that can be released with a small pocket size screwdriver. inside you will find 2 screens, see if they are stopped up. you can clean them and put back together. Just so you will know, some of these have a round piece that looks like a large pick up. this may fall off when you pick the assembly up out of tank. just put it back when you put it in tank. it rest on bottem of tank and cannot come out once installed. GOOD LUCK

i suspect u need to try and bleed the system

check the glow plugs circuit to ensure that the pre-combustion chambers are being suficiently heated. also fuel cetane rating must be high enough for cold weather starting. diesel will gel when cold if the cetane rating is low non winter diesel that is. A good fuel stabilizer could help. hope this helps

sounds like a bad wire buy a chilton book it's a great reference

You may have to attempt to jack the tranny up somemore and get it even though it really wont give you much more room.I have never removed intake to do one although,being on the ground and not a lift changes things.Removeing transmission will give you clearance and will let you clean area better for when you put it back together.

if its a 7.3 check your starter and cables.i had the e 50 with 7.3 was the starter. warning be prepaired for sticker shock on price they arnt cheap

they just screw together hold the out side piece the rear screws on to tighten

I have a feeling you got a wholed of unleaded fuel or bad fuel
I drive a diesel box truck the station I always took it to the fuelman put unleaded in the diesal tanks and the truck just died it had to have the gas tank completed drained and cleaned out but also ask yourself how many miles are on it and when was last tune up and if you live in a cold climate I recommend a heater block plug
