Hey guys, I'll start off by saying I'm an auto tech of 10 years experience, ASE certs ect.... now on to the problem:
I've got a 2000 ranger 3.0 I bought from a customer a year ago with blown head gaskets. I rebuilt the motor top to bottom, new everything. It's been good but it's developed a hard start, severe misfire. initially found a clogged fuel filter, replaced it but didnt solve it. threw a 303, ended up replacing an injector. started it up and ran just as bad with a 305. replaced the injector on 5 now its missing on 3 and 5, which i verified by pulling wires and listening for difference in how it ran. Still misses on those cylinders yet will not throw any codes. Coil is hitting, spark at the plug....
Tested and known good:
Coil pack
CMP
Injectors
Compression
wires/plugs
pulled valve cover to verify rockers are functioning. Used a noid light on the injectors, all fire. I'm totally at a loss with this truck. Anyone got a thought?
