2000 Excursion 7.3l Missing
First off thanks for all the great info on this site. I have been trolling here for a while but decided it is time to post my problem.
I have a 2000 7.3l excursion that is running rough when warm. Here are the things I have done so far.
I picked up AutoEnginuity ran some test with the following results.
p0279 Cyl 7 injector circuit low
p1271 Cyl #1 high low side open
p1273 Cyl #3 high low side open
p1275 Cyl #5 high low side open
p1277 Cyl #7 high low side open
I replaced the CPS also
I did the buzz test and did not notice any difference in the injector sounds.
I have replaced the gasket on that side and also the internal wiring (to the glow plugs and injectors) and even spliced in a new external connector. It was a kit at autozone that has all the wiring also.
When cold it is fine but one warm it idles very rough.
