Well I replaced the ignition switch and no luck. If you have an ecu, I would much appreciate one. Pm me a price when you have time? I do PayPal or?Some 93s had a bad ECU. They revised it later on. I have ecus if you need one.
Grey plug has 12v, as well as both other links. I'm down to a bad ecu I guess.?The fusible link have 2 link. AM1 ( Black wire) is for the starter. AM2 ( White wire ) is the ignition system, which included ignition coil system, injector and power to the ecu.
I do not have 12v at ecu-cig. Ugh. I have another engine harness, but what a bitch to switch out, and it very well could be in the dash harness?Do you have 12v at the ECU-IG fuse with key in ON position? If you don't its not the ECU, possibly a wiring harness issue.
Thats what I was thinking. This is gonna suck. Thanks for your time.I would trace the wires and try to find the damaged wire before replacing the whole harness. I don't think that particular circuit is part of the engine harness.
I'm going out to the garage in a bit, ill see what I can find. Thanks for the response and the diagram.if you dont have power to the 7.5 amp fuse Ecu-ign, i don't think is the engine harness. Check to see if you have power to the Black-Red wire at the igntion wire.View attachment 2292808
It has 12v. I wonder if the tvss system cuts ignition if faulty?Check the 10amp Gauge fuse in the dash. I believe that fuse is for the check engine light
No power to ECU,Hi, Run the codes. Mike

The other two bits were laying in the bottom of the housing. It looks like they were soldered to the board under the connector posts. I reassembled and to my surprise it runs great. I may need a new afm at some point, but I'm not chasing wires! Thanks to all of you that helped me out. I learned a ton about the electrical system in my rig. Thanks.It runs, finally, and for a weird reason.
I read an unrelated post about the AFM (I think that's what it's called, correct me if I'm wrong) creating a no start issue but would let the engine start for a second when unplugged.
I unplugged my afm, and when I turned the key to the run position I had a CEL light finally! It would start for a second then die.
I then removed the afm, and cut the top off like I've seen in other posts, and I found a bit of metal that was crossing two of the connector posts.
