Aerostar not starting - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

1992 Aerostar won't start, no spark, TFI remotely mounted on fender. It only has 6 plug connector compared to distributor mounted module that has 6 plug connector plus 3 on module.
I can't seem to get any spark from the coil.
I have power into the coil but not getting anything out of coil.
I have changed coil, wires, plugs, cap, rotor, and tfi module.
Am I missing something ??

Is it possible that the ignition switch itself may be gone , the distributor , or even the computer.
I have tested resisitance through the distributor plug in and tfi with it plugged in and unplugged and all seems to be working.
I also noticed that when the distributor is manually moved the fuel pump kicks in when the vane passes #1 plug.
I am getting fuel but no spark.
Any help would be appreciated.

I had the same problem also. My solution, after days of exhaustive troubleshooting and replacing parts also...I finally bought a cheap fuse test light, and checked the connector that goes into the coil. There was just a little bit of corrosion on one of the wires inside the connector, I scraped it with a wire brush and a finishing nail. I put the connector back on the coil and my van fired up on the first crank.
So, I recommend checking your connectors along your ignition system and removing even the smallest piece of corrosion or rust on them. It worked for me. And it was something that can be easily overlooked.
Lemme know if that helps you out....Good Luck, Buddy.

Thanks a million, I took apart the connectors to the coil and scraped them down to bare metal. After reconnecting it fired up right away. Amazing what a little corrosion can do!
