Ran fine last night, wouldn't start this morning

ive always jumped it at the relay with coil wire off (away from fuel) and the key in the run position. it only takes a good bump to see a spark

This is not a legitimate test, because it ..............ready............? "bypasses" the start "bypass" circuit.

What I mean is, if the car has no start and the reason is the start / bypass circuit, you have hid the problem by jumpering the start relay. The ignition system will be getting power from "ignition run" which is COLD in "crank."

Worse, with any system using a ballast resistor, when you test by jumpering the resistor, you FURTHER lower the voltage to the ignition because..............

the battery voltage is dropped by the starter,

and the ballast resistor is still in the circuit.

That means that you might see a fairly weak spark, and conclude that you have a weak component, like a bad coil.


If you don't have 10' long arms, get a clip on "spark tester" or "rig" a spark plug so you can see it while operating the switch
