ignition spark goes away
Can you be more specific??? Did you check your spark plug wires.They could be frayed and start to arc. You could feel bucking and loss of power because of this.
A sudden loss of spark can be caused by a faulty crankshaft position sensor.
If the computer loses the signal from this sensor, the computer won’t operate the ignition system.
Tester
Starts and drives fine to first destination but will not re-start until an hour or more passes. Relay to fuel pump replaced (there was a spare in glove box) but it has fuel pressure at the rail. 40PSI
Check the ignition module.
