Fuel pumps all work,& filter only 6 mos. new.New cap & rotor new wires,,,new coil BUt the Base,Ignition Control relay is old,,This I suspect is the problem,,the NEW rsrelay on the passenger side refuses to click when I turn the key,,I cleaned the base & the contacts where the wires to the relay goes,,
Wonder If I am missing something else??

I'll Ask the Obvious 700

Test your battery with a voltmeter both static and attempting start. Before you start replacing parts.
Did it die driving?
Come out one morning and refused to start?
Did it start before you replaced the parts?

Spark, fuel, compression, spark at the right time. Agree with below. Timing belt either not timed properly or check plug wires.

The new Bougicord wires seem to e defective,,very weak spark,,,hot blue spark at coil wire,,warm weak spark at plug wire//
BUT the most obvious thing seems to be either I have a fuel leak & or someone stole gas while I was sleeping!!!I think I had 4 gals at least when it got towed back,,will dump some in & try again tomorrow...

"very weak..spark"


You mentioned fuel pumps (plural) so I assume you have a Bosch car vs Rex-Regina. Have you tried unbolting the ignition power stage and cleaning up its interfacing surfaces with the body chassis? I believe it's mounted to the inner LH fender in the engine compartment on that model car.

Also, might you have another coil you could swap in as a test?

If it's a Regina, that "plate" is a heatsink, and there should be a layer of special heat-conducting paste between it and the electronic amplifier. If you sanded the surfaces clean, it won't run for long.

Google "heatsink paste" or compound for what you need.
