Car runs for 45 seconds then quits, sometimes runs
for 3 minutes then quits. Replaced fuel filter,
getting fuel pressure. The only diagnostic code
is 12 (= No Problem Reported.) Any suggestions?
Ignition module under the distributor cap.
Cheap and easy to replace. Make sure
you put the thermo grease on the new one.
Thanks, Sean. Sure enough, it was the module.
With a new module ($35) it runs better than ever.
It was easy getting to the module inside the
distributor cap, but it was hard getting to the cap,
which is jammed back against the firewall. I had
to climb on top of the engine and remove other
hardware just to get to it.
It was worth the trouble. Runs sweet now.
Good luck to DIYers. Thanks again for the help.
