[QUOTE="I_like_turtlez, post: 16985033, member: 204906"] You're missing one of those things you think is in check You've given basically no information so I'm going to assume no MIL present on dash, car has sat for 24+ hours where rodents could've possibly gotten to it & that you don't have 6 month old gas in it. Also going to assume your anti-theft indicator isn't stuck on -Your starter works, so I can assume nominal amperage is provided to the starting circuit turning the flywheel over -Assuming you have opened the air inlet tube to check for a rodent nest or other obstruction(you'd be surprised what a dirty air filter can do) -Spray some cleaner(brake, throttle body, carb doesn't matter) in past the throttle body butterflies; if it starts and runs for a few seconds you know you have a fuel volume and/or pressure issue -Grab wiring diagrams for your entire ignition circuit, it's $20-40 for a 3-30 day period which is all you need as you can simply print them off. It sounds like your car has the ability to start but you should still do simple checks on your powers and grounds to verify the ECM is commanding everything else to function. Coincidentally doing this will rule out everything the car needs to start and run electrically The chances of the electrical issue are lower but then again these are old cars now & you're in Idaho up North; corrosion is a mother-lover Chances are you're overlooking something simple but that's my general advice with the information presented, you can spend an untold amount of hours guessing/throwing parts or you can do what we do professionally by using logical process of elimination via testing [/QUOTE]
