I have a Mitsubishi MUT-1. The MUT-1 connects to the diagnostic plug behind the glove box. It will let you monitor all sorts of sensors, etc. If you want to borrow it, just let me know.

I have a throttle body coming so I'm going to change that out and if i still can't get this thing going I'm definitely going to take you up on that! Thanks again!

So I'm still dead in the water. I replaced the throttle body the sensors and the computer. This morning when I installed everything the car started up and it drove fine! Then when i got home i turned it off and it started again and was running fine. I left it off for a few minutes just to test it and when I went back to start it up again it wouldn't start!
I seriously don't know what to do now. I'm wondering if for some reason it could be the ignition switch? I have good continuity at the sensors on the throttle body, I have pretty much ruled that out. Do fuel pump relays go bad in these cars often? Thanks.

Haztoys, what is this wiring tune-up of which you speak? Un-plug and pull down the wiring all of it ..Clean and OHM the wiring ...Soak the wire plugs in white vineger..That cleans where the wire meets the connector ...Replace the ICM and TPS and MASS plugs ... Take all 'male' pins on the plugs and give them a'little' twist and the 'female' plugs a 'little' crimp so they fit better..Dig the wiring out at the back of the key and clean it ...Delectric grease the whole mess...Open up the ECU and look at it for hot spots..Make sure the ICM motor OHM is good at ICM and ECU plug so the ECU does not get cooked ... Mitsu have sh&^%ty wiring ...Its all can be fixed ..But no one ever wants to do this and chases their a$$ trying to get one to run right ...Peace mealing the wiring is a long road.. Im really starting to consider doing this at this point. How do i check if the ICM motor is good? I have never really checked things with an OHM meter before, i did set the TPS with one but i still don't know if i really did it right. Thanks.

I would suggest downloading a copy of the 1989 Diagnostic Manual. It on the www.mitsubishilinks.com/ website. Look for "raider_fsm_1989_powertraindiagnostics-30l" The manual has a wealth of step by step tests to find and fix all sorts of conditions. It has a section on 'no-start' conditions too. If you (or anyone else) would like to borrow a Mitsubishi MUT-I, just send me a PM.

No restart after a hot soak, and then starting after a complete cool down looks like an electronic component heat related failure. Try cooling down the black box power tranistor on the coil bracket and the dizzy body with some kind of spray, like an r134 refill kit with the trigger, one component per start attempt.
Test for spark after a no start, and smell the tail pipe for a fuel smell. Does the tach respond while cranking?
