    7.3 idi hard to start unless use starting fluid or block heater

    Do you have battery power at the glow plug relay? If so do you have battery power on the output terminal to the glow plugs when energized? Just because the relay clicks does not mean you are getting power out to the glow plugs. What vendor did you get your glow plugs from?

    MOUNTAIN ROAD TRIP Preparation!

    My experience is the glow plugs draw 200 amps cold plus or minus a couple. Wonder if you are getting OEM plugs or China junk. Where have you been sourcing your plugs?

    1989 7.3 idi puffing white smoke out of exhaust and backfiring

    First thing I would do is run a compression test and see what the basic condition of the engine is. That will tell you where you need to go next.

    Oil squirters

    Unless they are plugged why would you need to change them? The only reason I could think of is possibly they might had increased the flow with a factory turbo system. Look how many have had turbo's installed over the years and the oil coolers would have still be stock. With increased flow if...

    I HAVE AN UPDATE!!

    Well do not feel to bad. I have had this restoring project going for way to many years twenty two or more. I bought the car new in 1974. The one on the right is the one I am restoring. The one on the left is a parts car that lived it's life about 5 miles from the house. It supplied the engine as...

    FIXED (I think): Solenoid feed wires hot, and voltage drop

    https://www.ford-trucks.com/forums/1029056-6-9-7-3-idi-diesel-tech-info-3.html Lots of information on glow plugs on that site. If the solenoid post was that hot I think I would change it. Sounds like the contacts inside are about shot. Is any of the glow plug controller wiring left and if so...

    FIXED (I think): Solenoid feed wires hot, and voltage drop

    Question what vendor did you get the Motorcraft plugs from? Define really hot. The glow plug system draws close to 200 amps when they first start heating. You will get a voltage drop as Ford did not use large enough wires for that load. My understanding is they were wanting to lower the actually...

    Injection pump gone bad.

    When was the last time the injectors were pressure and leak tested? If they are out of specs they can cause several issues.

    6.9 no start below 60 degrees or so

    Depends on temp. Either half if above 32 or to the floor below and hold. I usually go to the floor as it will not hurt anything. Just let up when it starts. Pumping does nothing on a diesel.

    6.9 no start below 60 degrees or so

    6.9 no start below 60 degrees or so

    Always start with the easy cheep things. A working block heater will tell a very good story and help led you down the correct path.

    6.9 no start below 60 degrees or so

    Plug the block heater in for a couple of hours and see what it does, that is if the block heater works.

    70 amps alternator wire question

    What condition are your battery cables in? Have you done any voltage drop test on those cables and the ground side of the system? Battery cables can do some very strange things at times. Last summer I started mine and ran it ten miles to a field (I farm) went to go home and truck was dead as...

    So what did you do with your truck today?

    Normally I do all my own tire work, however I got lazy and took the truck to a tire shop to get an inside dual repaired. The air filter restriction gauge said I needed a new filter so picked that up while I was also in town.

    So what did you do with your truck today?

    After hauling a load of trash to the dumpsters and then some cedar post for kindling. I blew out the cab and gave it a bath. Taking my wife to lunch tomorrow and hauling home a steer from the butcher shop so thought she deserved a little cleaner truck then what it often is since it is a farm truck.
