If it's a fuel injected engine with a distributor, see if you hear the
fuel pump run for about 2 seconds when you switch on the key to run (not
If so, check for spark by removing one of the plug wires and holding it
near metal - better to take an old plug and lay it on metal, spark should
be brisk snap and blue.
- if no spark, the age of car indicates problem may be the ignition
module (TFI). USUALLY mounted on dist base. requires a $5 tool (any
parts store) to remove.
You may find the white stuff on the back to be fairly hard and caky..
this is what causes that failure. The TFI overheats because it cant
dissipate internal heat.
Periodically (about every 5 years) replacing this heat sink grease before
it dries prevents this problem.
Be sure to clean off all the old and apply new when you replace the TFI
OTOH if it has been raining there, and the engine is wet from
condensation, the problem is often the coil arcing to it's frame. This
would have been pre-indicated by car being hard to start on wet mornings.
If you dont hear fuel pump run, make sure the inertia impact cut-out
hasnt been tripped, located in trunk usually on back or side rear...
often access hole through panel. Push button on top.
If still no FP run, then you will have to troubleshoot relay, Check
engine light on mean the Computer relay works, the comp in turn switches
the FP relay.
