Three times my car has suddenly died while driving in town. Two of the times it was a rainy day. I didn’t hit any puddles of water. First two times the motor started again with no problem and ran normal. The third time it didn’t want to start. Three hours later it fired right up and ran normally and I drove it home.
I did a fuel pressure test and noted that when the pressure hose was attached to the Schrader valve no gas came out. I attached the pressure gauge to the line and had my wife turn on the ignition but not start.
Zero pressure reading with ignition on. (I had previously removed and then replaced the gas cap to relieve pressure.)
The motor was started and the pressure went to 38 and held steady at idle. Increased RPM and no change in the reading, still at 38.
Engine off then ignition on and the pressure instantly hit 48 and slowly and then more rapidly returned to zero.
I started the motor and let it idle, pressure at 38. It ran for about 5 minutes, ran rough like on 2 cylinders and then died. Before it died, the pressure shot up to 56, held for a moment and then slowly went to zero.
I waited for a few minutes, started motor and same scenario.
When the motor is running, it sounds normal and runs normal - until it dies.
Any ideas as to why the motor is suddenly dying? Maybe the fuel filter or fuel pump? No codes observed. It's a 92 automatic.
Looking for comments and suggestions. Any help appreciated.
