I'm totally baffled and hope someone can help.
My 81 240 GL died due a shorted harness. Temp gauge
when full hot, motor would spin, but not start.
Replaced harness with new temp sensors as you suggest.
Car started, but quit due to blown fuel pump fuse.
Replaced fuse and when key switched to on position, the
car started and ran but with starter still engaged. Pulled
battery cable to stop.
Checked BrickBoard and found that the CPR terminals may
need reversing for my year model. Resistance across
CPR terminals is 14 ohms, but neither terminal is grounded
as was suggested by the BrickBoard posting. Old harness
and new both have black wire in the same place.
Pulled fuel pump relay and jumpered terminals 30 and 87
to get fuel pump to run with CPR disconnected. Car started
and ran for a while, but the jumper wire got hot and car
quit.
Reconnected everything as before and left CPR disconnected
and car started when key turned to on position with starter staying
engaged.
Double checked my harness connections with Haynes
wiring diagram and all are correct.
Original, blown fuel pump fuse was too small, new one is
the correct 16A and has not blown.
Questions:
1. Should CPR have one terminal that is grounded to the case?
2. Can these be repaired if not?
3. Can a bad ignition or fuel pump relay keep the starter
engaged? If so, which one?
Very grateful for any insight.
