UPDATE...
THE PROBLEM IS SOLVED!!!
First of all, thank you to everyone who shared suggestions and ideas on
what to check.
It turns out that the local AC shop who installed my new AC compressor
CHANGED the wiring to my starter solenoid!!! :(
It seems that after they installed my new AC compressor, they couldn't
get the car started. They told me that the vacuum line to the EIS
controller/box was ruptured or torn (they must have done it because
there were no problems before I took it to them), so they cut off the
ruptured section and all was good they said. However, the vacuum line
is for the A/C compressor control electronics within the EIS, so I
doubt that had anything to do with causing the car not to start.
Anyway, the shop failed to tell me everything else they must have tried
to get the car started BEFORE they discovered the "ruptured vacuum
line."
I have a PMGR mini hi-torque starter (from DB Electrical) which
requires that the starter lead be moved to the battery/input side of
the solenoid, and a new 12 ga. trigger wire be added at the output side
of the solenoid and run to the starter. The Pantera Electronics EIS
has a safety feature which disables the ignition in the event of a
sudden loss of oil pressure.
Inline image
The idiots at the AC shop moved all the wiring connections to the
output side of the starter solenoid, effectively bypassing the OEM
solenoid in favor of the PMGR starter's integral solenoid. However,
the EIS has a wire lead that connects to the 'S' post on the OEM
solenoid in the attached illustration which triggers a time delay for
the oil pressure safety feature. By moving the wiring and bypassing
the OEM solenoid the EIS failed to receive a signal to trigger the time
delay on the ignition cut-off safety feature. Therefore, the car would
not start. Sometimes the car would start, but I suspect it was only
after cranking enough to build up sufficient oil pressure. And it would
start with the battery booster or a jump-start, but again only after a
lot of cranking, so again, it probably built up sufficient oil pressure
to allow the ignition to trigger.
I returned the solenoid wiring to the correct orientation on Sunday
night, and the car has started without hesitation or issue every time
since! And I've been driving it daily to make sure there's no more
problem.
Anyway, thanks for all the help and suggestions!
Cheers!
Garth
