No Spark, Help Please!
Please help! I have a motorhome on a 1985 E 350 chassis that will not start. It has no spark untill the key is turned off, then it will spark once immedaitely after with the momentum of the engines rotation after the key switch is turned to off. I have already changed the ingnition module, didn't help. What should I change next?

Thanks for the reply 220k.
I'v got 3.3 Volts on the positive side of the coil in run mode and 4.4 V in start mode. Is the enough? Maybe a bad coil? So far I've changed the ignition switch, the stator, and the ignition module!!

doesn't mean bad coil, but the voltage to the coil should be about 6-8 volts in run mode. Before you try anything else, have you made sure that the distributor is turning. Take cap off, and make sure rotor spins when trying to start. Also make sure you are getting good ground to that Voltmeter while trying in the run mode.
Check wiring. between dist. and ignition module.
