[V6-12v] Motor wont start G28 Andrew Muff

[Andrew Muff]

Hey Doug,

Well, the line I've had a couple of sources tell me to investigate further
is a missing or poorly connected ground wire. It's possible and all the
symptoms fit.

I'll let you know what I find.

I am having similar troubles with a 94CSQ AAH V6 2.8l - car was rescued, new
clutch, flywheel, slave & master  installed, got it running "perfect" for
3-4 weeks then one day it refused to start. have swapped out coil pack POS,
cam, crank, speed sensors, checked all fuses, fuel pump cycling and fuel at
FPR on the rail..

 

"Update: no ignition. Volt meter shows power to the injectors but no pulse.
An open spark plug hole confirms no fuel either. Seems like the ECU doesn't
want this engine to start. But still no codes. Ideas?

Just tested for spark and both #1 and #4 cyl are dead, so the whole ignition
coil has no power. I've traced back the wires and confirmed these are
plugged into the right harness by confirming wire colors with the schematic.
