    6.9 quit

    My experience with a dead lift pump is it runs after the pump quits until it is turned off and will not restart. Good advice to start with a jerry can and eliminate that. Make sure the pump return line isn't blocked in the pump. Make certain the shut off has power like has been suggested.

    7.3 ambulance First ever Deisel

    Tire shine can sometimes stop a squeaking belt. That assumes it is in good shape to begin with. We have a customer at work who has a 97 ambulance. I've gained a lot of wiring experience lately.

    Project has been back burnered again as the shop gets busier. I can understand the reasoning for what has been suggested though. Appreciate the help.

    Checked all glow plugs with a halogen headlight. Bad one is in #8. Will power that headlight through the glow plug harness. Looks like a compression test is next. Injectors all make noise during buzz test, some much louder than others. No codes set during test.

    Most engines won't fire without 500 psi injector oil pressure.

    Some cylinders are really loud when they fire. Lots of clatter.

    Tried to start this beast this morning. Rainy, 9C,(48F). Checked oil reservoir, normal. Cranked after glow plugs for 10 seconds. Tried to fire but died. Oil reservoir still good. 10 seconds more cranking. Still good. Didn't fire at all. Got scan tool from shop. No codes. ICP reads 2800...

    Body did not change 97 to 03. Cover will come off but it is a fight. Removing the downpipe helps.

    Electrically the engine passes all the tests. While running, it runs rough and settles into a constant misfire.

    Didn't check. Every time I have checked it it has been an inch or so from the top.

    So much for one theory. Oil reservoir is full after a 4 day sit. Cranked for 10 seconds after wait to start light went out. Fired a handful of cylinders then nothing. Gave up and let it sit.

    I'm a little baffled that 150 psi air would blow open the check valves but I guess back pressure isn't really a problem.

    I can barely get my head in there as it is. Van body. Also, I hope the computers will pick up on any electrical anomalies.

    I can check the reservoir Monday at work. This is a 7.3. I may have used the wrong term.

    Reservoir has always had the proper amount of oil when checked. Vehicle was driven about 20 miles after we worked on it to work out air. The longer this thing sits, the harder it is to start. Even after the drive it idles like it is only working on 7 cylinders at most. Customer just wants it...

    65 psi at the frame mounted pump as soon as the pump runs. #1 cylinder fails cylinder contribution test hot or cold. Wiring checks out to the ficm. If I missed something I am all ears. Started it yesterday. Took forever to start, ran rough with a dead miss. Engine oil pressure on dash took...

    Valve covers are on it right now. I didn't pay attention to the brand of glow plugs. The engine shakes even when at operating temp. Can't drive it anymore because it has a separated flat tire. Customer is trying to sell the vehicle.

    We replaced #1 injector. No change.

    The misfire goes on too long to just be a glow plug. I'm starting to think a compression test is next. I hate working on vans...

    Glow plugs have been tested with an ohmeter and a headlight. May need to test the wiring under load.

    E40D Help!

    Anything is possible. Good to know.

    I moved it to 8 so it was easier to reach. The other 7 are good, as is the harness from the relay to the plugs.

    I'm curious what the significance of the dome light is. What circuit is it tied to

    This is the first time I've seen this vehicle. There is no history. A compression test on a diesel is difficult but double the difficulty in a van chassis. It has one dead glow plug, now located in cylinder number 8. Number 1 keeps showing weak.

    We have a cube van that is driving us nuts at work. It will start fine warm but 4 or 5 hours is enough to make for long cranks, white, eye-burning smoke, and a rough idle. We replaced the IDM as per the diagnosis of the misfire or cylinder contribution codes. All resistances are well within...
