Just bought this vehicle to fix. Not running at present, turns over fine, but no fuel, no spark. Mechanic that last guy used says it needs either new ignition module, or if that doesn't work, new computer. If it IS the computer, can I put in one from any years 1985-1991 assuming the same engine? (2.5L I4)

Check with salvage yard or autoparts store for ECM years that are interchangeable. Don't forget to remove your PROM from old computer.
