Subject: help. again.
The '87 16V is letting me down.
It's still dying momentarily, only now the "momentarily" is long =
enough to force me to the side of the road for 30 seconds. It still =
fires right back up after and runs as if nothing happened (runs for 10 =
seconds or 5 days.....).
Symptoms: ignition goes dead for from 1/10 second to 30 seconds. =
Tach instantly drops to zero, even though the motor is still turning =
over 3000 rpm as it coasts to a stop. All other electrical items seem =
to be unaffected (lights, radio, voltmeter and other gauges, etc.all =
work the whole time) It's random; every three or four days or so it =
will have a fit of this frustrating behavior. Fuel flow seems normal as =
it usually backfires slightly when the ignition kicks back on.....
I've re-cleaned all the grounds in the engine compartment. (even =
though it acted completely different when the grounds were bad)
Installed new fuel pump relay, just in case.
Installed new Hall affect sender.
Installed new coil.
Installed new ignition control unit/module.
Checked and cleaned all connections in engine compartment.
Diagnosed knock sensor unit. (no reported faults)
Battery and alternator are good (consistent 13 - 14 volts)
New ignition switch. (wiggling the key does not cause the dying)
Fuel tank level has no discernable affect, (full or near empty).
Can happen immediately after start-up, cold or warm, or after 20 =
minutes of driving.
I'm getting desperate. (Desperate enough to drive my Chevy van to =
work the last few days....)
Someone on this list has an idea that I haven't been able to think =
of.....and one of those ideas will be IT!
