So,code is cam shaft out of phase. I researched & ordered cam/crank sensors. I have a service manual on these units. We installed sensors with no success. We have power going to cam sensor. We are now in the process of checking fuses,relays,ignition switch,sensor harness plug connections continuity,ecm plug connections,continuity paths from sensors to ground/power source & signal to ecm pin.
I have read all the reports related to code 28 & others related to the subject of no spark. Does anyone know what the common issue is with this code,because it seems, judging from the reports that no one has found it yet. Lots of unanswered questions in regards to this code.
The truck is down as I write this report. Call me if you know @ 262-677-9925 Jeff.
