Re: 1998 3 cylinder firefly won't start!

The '94 distributor is not capatible with the '98 powertrain control system. None the less the car should have at least started.

You can rule out the coil by attaching a testlight/voltmeter between the blk/wht and brn/wht coil wires to look for flashing/voltage fluctuation while cranking. Flashing/voltage fluctuation + no spark = bad coil.



If you don't get flash at all verify voltage at the blk/wht coil wire with the key on then my next best guess would be the ignition control module, as they tend to die suddenly, instead of degrade over time. If you don't get voltage from the blk/wht coil wire with the key on you've either got a blown IG fuse or an open circuit.

Also be sure to double check your sensor grounds behind the intake manifold, as this is where the ICM grounds the coil primary circuit.

Goodluck and keep us posted.
