do the injectors pulse? no pulse, no injectors=crank sensor.

no injectors and HAS spark=ecu and/or relay.

injectors DO pulse and no spark=ignition module-most likely. ignition ecu is possible but VERY unlikely. this ASSUMES we are looking for spark at the coil and not the plugs. spark at the coil and no spark at the plugs is cap, rotor and/or wires.

given the condition of the fuel ecu, a new one may be necessary, but it WILL NOT cause a no spark condition.

it also sounds like you need a new mechanic. good luck, chuck.
