so i just got the car and already replaced the starter...it idle really high and if it drops it wants to die...ive had two separate shops tell me the problem is electrical...its is cold this morning and my car will just not turn over...the lights and all come on no prob just nothing as far as the engine...the fuel pump seems to want to die but i cant help but feel that if i can solve the electrical the rest will fall into place...when it runs, it runs decently except for shaky high idle...i really want to fix this car because ive already got some stickers on it...ive had it start then die on me a few times then finally catch on and survive...

Welcome to the forum, thanks for the donation. If it cranks good but won't start, have a helper crank it, while you visually check for spark at the plugs. Use a gage and check fuel pressure. Your obd1, you should be able to check for codes, if there are any? I looked at some info on your vehicle, didn't see maf sensor. With a speed density system, map sensor only, a vacuum leak will cause a high idle. I realize your thinking about electrical issues, but, I have to go through the basic checks, first, that is just how I go forward.

If the starter won't crank, make sure the battery has a full charge and the connections are good. Can you tell if there is a load on the starter circuit, key in the crank position? Watch the headlites when you turn key to crank, do they dim--go out-pulse? If they stay bright, no reaction, check for open circuit to the starter, possibilities, faulty wiring circuit on the purple wire-- neutral switch-- ignition switch. If the lights go out, usually the battery or cables, can't rule out the starter itself.
