You dont have a fault for distributor reference signal (No distributor
reference signal detected during cranking) You dont have a fault for
Injector peak current (caused by high resistance in the control circuit)
which is also the PCM test, You dont have a fault for injector control
circuit ( engine controller does not sense injector switching on and off
when a control is switched) so all those tests i would assumed pass, the
only thing it does not test is if the pintel is opening, you would need a
lab scope for that. but as our friend Dan C states, they did not have many
problems with that injector, but then again the car is 14 yrs old, once
again, if you supply fuel(starter fluid) and the engine runs and all other
test passed especially the TPS sensor ( cause if will shut off fuel) and the
speed sensor cause it will also cause a no start if bad, then i would have
to say the injector is faulty, assuming all others passed, this is the last
post i will make to this, i dont get into these games with people like
daniel. there was also a recall out on the 2.5/2.2 for replacement of the
injector, im not sure what yr it was , give me the serial number via my e
mail address and i will check for you. it may have been 1988 im not sure
