rough running after new o rings and more obs 7.3
ok new to forums so bare with me but thought i would try
my 96 f350 7.3 needed injector o rings and a fuel pump and when i started pulling it apart i noticed at every connection going to the valve covers the connectors were falling apart also my wiring harness going through the fuel filter canister was falling apart(it had been leaking fuel on the wires for a while) also the orange air intake boots were shot.
sooo i ordered up new intake boots from riffraff an entire new fuek filter canister with harness(motorcraft) alliant injector o rings, deisel rx glow plugs, alliant fuel pump, and whatever valve cover gaskets napa gave me and wired on the new connectors
after i did the o rings i sucked as much oil out of cylinders as i could then turned motor over by hand and it turned good. finally got truck running and drove about 50 miles running like crap whole time, no power rough idle long cranks. got home and noticed a fuel leak, i forgot to tighten a rubber fuel line. i drove it again about 5 miles truck acts the same. checked hpop and its full. do you think that with the fuel line leaking it pulled in air and i need to repeat the driving process? only other thing it thought was my wiring job was a fail. if i unplug any one of the four connectors going to valve covers it will die. probably left some info out... thoughts? also there is a check engine light which i figured would be on due to cranking motor over with injector/glow plug harness undone but i have hooked 2 scanners to truck and neither one is picking up a fault code
