It turns over but pops and back fires, we tried to run it on ether to see if it was a fuel problem but it still would not run.

    that would be a good place to start, at that many miles anything can be wrong, the whole system is pretty near death.

Car will start, but shut off immediately


You need to reset the security system. Try to start it. The light will blink. Leave the key in the run position until the light stops blinking. It will take about 11 minutes. Shut the key off. On the next key cycle the system will reset and the car should start and run.

Solved most of this myself. Changed ING. module which solved spark problem. The injectors still would not function, help came from JUSTANSWERS by idenifying a relay tucked between the left headlight motor and the coolant recovery canister. Like the IGN. module, this relays not cheap. I found a $5 dollar used replacement from a self-pull wrecking yard from it's sister car, a 1988 mazda 323.

Starts and runs 3-5 seconds and shuts down


Sounds like your security system is shutting the car down. You should be able to leave the key on for 15 minutes and it will reset itself. Make sure you are using factory keys, and they are in good condition.

Check all battery connections, wiring at alternator, for scorched ends, loose and/or corroded connections, as well as any power distribution boxes under hood. take close look at belt(s) for scorched or burnt edges, or deep grooves, as sign of trouble.Personally if I didn't find anything obvious, I would remove belt (s) and try moving all pulleys & idlers by hand, and feel for binding etc. When that's done, if you must, have someone start & be ready to shut it down quickly, as you observe pulleys, belts etc.
