Use a meter and check for the 12 volts at the coil. If you don't have it, work up the line until you find it and fix the break.

Your truck should have a hall effect sensor in the distributor for electronic ignition, with a module on the fender or on the coil. Check these both for proper signal and lose/dirty connectors. Check the ground on the module.

Can you, temporary-like, run a hot wire to the coil + terminal? That should bypass the ignition switch portion of the circuit. I should say that will bypass the 'run' position of the ignition switch. You'll still have to turn the key all the way for cranking power. Unless the ignition switch is bad/dead completely. Then you have to jumper the starter solenoid. I know it works well on the older Chrysler vehicles for diagnostic purposes, but I'm no pro with these Jap ones.

Good luck,
Anthony

just a note to possibly save from havign to spend extra money .Jumper wires and electronic ignition do not mix .Unless you know exactly what and why you are jumping . Good way to fry and otherwise good module /coil / or pick up coil . See if you have voltage on + sid eof coil with side test light while cranking .If so check neg side while cranking shoudl have pulsing light .If no pulse possible hall effect switch in dist. or module . Some of these module /coil /ignitor s are very high $$$$ I have adapted Gm module to some of these and work fine $18 verse $400 saaved big time there

Have you checked to see if the distributor shaft
is turning while the engine is cranking over?

I don't know what engine you have, but timing belts and chains that break are common in these little Ornamental units. Then, the camshaft and distributor no longer rotate, and the valves often get up close and personal with the pistons.

If this is NOT the problem, some of these little outfits had really crappy ignition switches that can fail, and not power up the ignition.

Hi Bob the distributor shaft does move could it still be the belts and chain? Thanks

If the timing belt or chain is turning the distributor, you would have spark, even though the timing COULD be "off", if something had "jumped time".

Since you say you have NO spark there must be something else wrong. What year? What engine?
