2001 7.3 engine replacement
A friend of mine just got finished replacing the 7.3 in my 2001 supercab last week. The old engine was 150 psi or so low on compression on 1 cylinder. (Had a bad hose between air cleaner and turbo.) The engine we put in is out of a F450 with 160000 miles. He got it running and seems to have 1 cylinder with a miss. Lot of white smoke out of the exhaust. He used the injectors and glow plugs out of the old engine which have only 2000 miles on them. He buzz tested the injectors and they are good. Ohm checked all wires to injectors and apparently is ok. He gets a code for Injector drive module, but this was replaced last summer too, about 2500 miles on it. All the sensors were used off the original engine. Any good ideas? Main computer? He thought the main computer could be damaging the IDM?
The more money I have to spend on this truck the more I like my 92 6.5 chevy. Other than an engine at 300000 it is way more reliable than this Ford at 112000.
Why did it need the front axle totally redone at this low mileage? My Chevy didn't need anything until over 200000. I can't believe all this electrical crap on these Fords. If I ever get it running good it's going down the road. I've spent well over $6500 on this truck not including this engine.
