Code #19 ?

[Boosted92LX]

No power to processor code.

The engine will momentarily cut out, tach drops to 0, then jumps right back up and carries on like nothing happened. I changed out the ignition switch and thought I had it fixed, but the problem came back.

Has anyone ever experienced this? A buddy told me to check the ignition module on the distributor, but I wouldn't think that would cause these symptoms or that code...

Any help would be appreciated!

Code 19 - Engine off - No Vehicle Power (pins 37 + 57) or bad PCM VPWR Diagnosis. This is a wiring problem that is from a bad ECC power relay, bad connection, bad fuse link, bad ignition switch or a bad computer. The ECC relay is located on top of the computer under the passenger side kick panel. Pull the connector off any fuel injector and measure the voltage on the red wire: if its 12 volts or better, the ECC relay is OK. If the ECC relay is OK, pull the kick panel off and measure the voltage at pins 37 & 57. If it is 12 volts or more, then the computer's diagnostic firmware has taken a dump and is defective.

Engine running - Erratic idle during test (reset throttle & retest) - Idle Set Procedures

Thanks, jrichker.

I did an engine off test, so I guess it's time to break out the voltmeter. At least I know where to start know!
