Does anyone have a known good DIS they can loan me? I have three DIS modules and none of them will start my 1991 SC. If anyone in the N Bay Area has a known good one to loan me, I would sure appreciate it.
I have three or four used ones - got tired of wondering if they were any good and just went a bought a new one. Prices now seem to have come down, so good news that. $60 autozone w/limited lifetime warranty. The one I bought came with the dielectric grease that goes on the bottom.
I have three DIS's. One new $60 for the up to 1990, and one new $200 1991-92. I am getting 212 and 214 on one of them and just 214 on the other. I have new cam and crank sensors. I thought it was the wiring, but it was a bad connection on a lead to the ohm meter!!! I have the wiring apart now but all tests ok and can find no corrosion.
Use caution busting them open - Ford went to a lot of trouble to include shielding to reduce EMI and phantom signals, etc. Might cause more damage if not careful. My original was hacked/damaged and oil soaked - suspect someone opened it up for troubleshooting that ended up being cam sensor and grounds. I fished good condition used ones off donor cars and spent 10 hrs each in cleanup, replacing broken connectors and rewrapping with similar cloth tape the factory used...then I sprayed them w/clear epoxy paint to seal/protect. I still have a refurb'd '91 front harness for sale - http://www.sccoa.com/forums/showthr...pper-Front-Harness-For-Sale&highlight=harness
I'd offer to send a couple of used ones to check with, but no idea if they're any good...
Have you gone thru this no-start troubleshooting flowchart?
