First question - how many miles are on the vehicle? What has been tested so far? Why are these various parts being replaced?

With the ignition and key 'ON' - do you hear the fuel pump running?

Attach an OBD1 code reader and retrieve any stored fault codes.

Check for these conditions before throwing more money / time at the problem;

- Air flow; filter condition, no leaks in the air intake system

- Fuel flow and pressure, attach a fuel pressure gauge. Connect it at the fuel rail and measure the fuel pressure when cranking the engine over. Should be around 65 PSI.

- Ignition (spark) at the spark plugs
