Driving in town about 30 mph when the car lost power. It seemed as though it wasn't completely shut down, but rather trying to hang on in a very weakened state until it died.
I may have been late in looking to the tachometer but I did not see any movement on it.
When I made an effort to restart it tried to catch and seemed several times to be making some progress before it lightly backfired and died.
I tried moving the CPS lead around while it was being cranked but it did not produce any results- not even the weak effort it made to catch right before that.
While I was waiting for the roll back I swapped in a spare fuel injection relay as well as a radio suppression relay with no results.
The car has relatively new cap, rotor and ignition wires. The grounds on the engine and behind the headlights are clean and secure. Fuel filter changed less than 10K ago.
It was in the low 80's today and prior to it dying we had been sitting idling in traffic. The electric radiator fan kicked on.
When the roll back got us home the car had been off for about two hours. Given that time to ponder what might be wrong I thought perhaps the fuel pump had failed. I have no records for this car but it had about 175K on it when I bought it so I would guess the original pump had been replaced before my ownership.
I did not try to start it before giving it a healthy shot of starting fluid, but after giving it a good spray it started right up- and continued to run just fine for 10 or 15 minutes in the driveway before I shut it off. I started it and shut it off three or four times without a problem.
Thanks for ideas on what to chase.
