Hey everyone, just joined the site I have been on others but this thread seems to have people who know and work on the 7.3 DIT motor. I figurd I wold post here as I am having pretty much the same problem and maybe we all can come to an answer. He is a bit of info about my situation,
95 F350 7.3 DIT with about 165,000 on it, has been primarily a plow truck the last 10 years. The guy I bought it from did a 1st gen minute mount on the truck with the old 12 pin connectors, however I found out the hard way the guy did not know how to wire and wired the plow lights and power right into the main headlight and marker light harness. Well long story short I am anal and got fed up withy he lights going out going down the road, I pulled the wiring harnesses apart and removed all of his hacked wiring, I got down to the main harnesses and took forever to locate all of the wires to the markers and headlights even with a schematic. Today I made it a priority to finish the wiring as it was snowing tonight, got all the lights wired correctly and found one dead wire going to passenger marker lights so I wired a bypass 16 gauge from the rear marker wire that runs down behind the motor. All lights work now, all markers and directo
Iona's, my problem now is that throughout the day I was removing and reconnecting the three main wire distribution boxes, the two on the firewall that go to the inside fuses and inside functions as well as the wire loom to the injection control module on the drivers fender, I would say I had to remove them and reinstall them about 6 times each today just to check voltage and continuity of wires, I however being cold today and hands numb accidentally wacked the injection module controller with the ratchet today, I got everything buttoned up and went to start the truck wouldn't not kick over, it will crank and crank forever but just will not fire up. Throughout e whole process I had a battery charger on the main battery throughout the day while I had lights on, when I was finished with everything it just cranked and never fired and refuse to dump ether into the intake. Fishing around for the past 5 hours seeing what it could be came to the conclusion of many things, the ICP, CSP, oil pressure pump, fuel pump and of course the injection module controller I wacked with the ratchet. Now with about a foot of snow on the ground here in RI I am without my plow truck, I really need to get the truck running so I can plow my accounts tomorrow which I know probably is going to be a long shot. Does anyone know if a sudden shock to the injection control will disable it or fry it when I hit it with the ratchet, or possibly maybe fried something else during removal and installation of the distribution blocks so many times, I will also admit that once or twice I accidentally also removed the distribution blocks while the ignition key was on and flowing so I know I possibly may have fried something. I am at a stand still. I have all the manuals for the truck and can find all the sensors, just didn't really want to spend about $600 this weekend t get it up and going. There are a few things I will be checking in the morning which mainly will be the oil level in the reservoir for the high pressure pump, outside of that any suggestion with what I did today where the best place to start is. Any help is appreciated, thanks in advance.
