FORD= found on road dead ! or fix or repair daily

I had a 2004 F-150 5.4 and was nothing but problems , 4 injectors , bad fuel pump, and 3 set's of bushings in 2.5 years !! I now drive a dodge ram 1500 NO PROBLEMS

try unplugging one injector at a time and see if the noid light shows the other ones picking up, checking resistance on each injector will show the same thing. You may have an injector shorting to ground, causing the other injectors to miss fire

Ford fans tell me it is (FIRST ON RACE DAY)

FLIP OVER READ DIRECTIONS
With these distributorless ignitions the coil not only lites up the spark plugs but sends a signal to the fule injector

[shurlock]

yeah spare parts I will give that a try this Saturday busy with work right now. and will let you know. I myself was never a big Ford fan but the company bought it for me couple years back no one would say no to a free truck. has ran without a problem for the last 6 years not even a hick up until now.

I am getting spark to that cylinder

[spareparts]

ecu takes position signal from crank position sensor and cam position sensor. generally the coil driver and injector driver are separate, The ecu fires each independantly

[shurlock]

Yes spare parts you are definitely correct on that I replaced both camshaft position sensors for s**** and giggles when It started misfiring. I have a commercial account at Advanced Auto I get them for like $10. I had another friend with this same engine that had his cam phasers fail and that was quite a mission to do. going to check wire harness for shorts before I ordered Used ecm don't really feel like having to pay to reprogram chip Keys.
