#844 of 1186 Want start when WARM or HOT
Feb 21, 2010 (4:09 am)
I have a 1996 Ford F-250 4 wheel drive with a 7.0 and a 5 speed standard trans. If you want to call it my baby, it is. The trouble is she is sick. She starts great when she is cold but let her get warm or at running temp she will set there all day and turn over as if her batter would never die. Shut her with a little starting fluid she will start right up. I have not check anything as of yet, trying to get info before spending money on her. I think most of you can under stand that.... The Ford Company loves it when you walk in the door. They know who I am. Anyone with a GOOD PLACE to start.

Do you have any way to check ICP how many miles are on it and have the injectors ever been re sealed?

No way to check ICP except the Ford Co and my lady has 125000 on heand this the first trouble. I going to change the oil this week and all filters. She has been setting for about 2 yrs and not been run but a fue time a month.

Stanone: You may have a bit of maintenance to do in order to get her running right. First of all, be very careful with the use of starting fluid. Starting fluid strips the oil off the cylinder walls and can cause scoring of the walls and premature oil ring/seal failure. When I used to run heavy equipment, using starting fluid could be cause for job termination. Secondly, if the rig has been sitting for a couple of years, you could have lots of water in the fuel and possibly the formation of bio masses in your fuel tanks. You may need to drain them and put in fresh diesel. In order to drain the water from your filter housing, you will find a small yellow lever next to your fuel filter housing. I believe you can do the following: while motor is idling, open valve for about 20 to 30 seconds. Fuel will drain from a line near the front of the engine on the passenger side. You can catch most of it in an oil change collection pan. You will probably need a new fuel filter as you have indicated.
See how these maintenence fixes go. They will probably improve things a bit, but may not bring you all the way to optimum running conditions. Other issues could include glow plug relay and glow plugs. After those are checked, a next step might be your injectors. But....one step at a time with the less expensive and easier fixes first. You may need to check your batteries. If you need to replace them, consider getting them from Costco or Sam's Club, whichever you have in your neck of the woods.
Also, if she's been sitting, you may want to engage your 4X system just to get the gears and wheel locks lubricated.
At 125k she is just barely broke in.

#850 of 1186 7.3 won't start
Feb 22, 2010 (4:25 pm)
I read on another diesel forum. If the HPOP is low on oil the 7.3 won't start. Where is the HPOP reservoir and ICP sensor located.
Thanks for your help,

The HPOP reservoir is on top front center of engine, the ICP is on the passenger side in the center of the head on the intake side. And yes if the oil reservoir is low it wont start until it fills up when cranking. IS the vehicle hard to start after sitting over night? IF so then you could have an injector or injectors hanging open. The way to find that out is to get the engine started and let it run for awhile, then shut it off and remove both valve covers, on each injector there is what it called a spill spout, it is on the top side of the injector and it is usually square in shape and points downward. Place a small piece of clean cardboard under the spill spout and let sit overnight. Then check to see what piece of cardboard is oily, That will be the leaking injector and will have to be replaced.
IF you cant start the engine and suspect that the resrevoir is draining then there is a plug on the top of the reservoir. Use a standard screwdriver and remove the plug and fill it with engine oil and then perform the above test. good luck

What if the truck is at an idle and dies and it showing the the Voltage dropping below 1 Volt from the ICP Sensor, doesn't that lean more towards bad O-Rings ? Because we can watch the Voltage coming from it and as soon as the Voltage goes above 1 Volt it fires but below it dies.
