IM ABOUT READY TO RIP MY HAIR OUT

[ruffman]

I have a misfire, new injectors, new coil packs, new plugs. i finally found the problem but now i do not know what to do...the front cyl. on the drivers side does not have spark, there are 3 pins for the coil pack, all of the other 5 connectors are left pin-no power center pin-12vdc right pin-no power...front cyl. on drivers side is left pin-12vdc center pin-no power right pin-12vdc, has anybody ever had this issue and if so where do i start?

Do you have a new PTU or an old style PTU. If new inspect the jumper harness, mayb somone tried to solder it in and messed up the wiring. It's probably possible that someone pulled the pins out and put them in wrong. Check for any hackjobs on the wiring harness.

sounds like a bad PTU
