    does it have a ignition control module inside the distriburator on that model? if it does, change it.

    1.Check fuse links down on the starter to see if any are burned into.Check for power at the coils by removing the two plug wires on one coil.Now crank the engine and have someone see if their is an arc to each terminal.If so OK.2.Check for leaking vacuum line at the fuel pressure regulator.Correct all cracked or leaking vacuum lines.3.Check voltage at the throttle position sensor with ignition on/engine off.Voltage should be 1 to 5 volts.If higher voltage at this point replace computor(.eg 12 volts)

    the remote starter may be incorectly wired, killing the power to the coil packs. An anti theft unit that shuts down spark, if the wrong key is tried in the ign., may be bad

    I would guess module but it would depend on motor size. I'm assuming its a 4.3 if so it could be coil too. Hope that helps!

    coil pack(s) are what provide the spark. Check these out.

    Instead of throwing money at it changing parts, find out what the real problem is by having it looked at.
