Start first with checking to see if you are lacking injector pulse as well as n spark, take a 12 volt test light and place the test end on the power side of the injector connector and the ground end on the other wire and crank the engine over, if you have pulse the light should flash while cranking. Check this and let me know the results. Im here all day today.

I have checked the wires to the injectors one wire has no volts and the other has 12 volts and no pulsation while cranking. I have also checked the four wires at the ignition coil pack, one has no volt and the others three have 12.3 volts. none of these wires pulsate while cranking.

SO are saying you have no injector pulse and no spark to the spark plugs?
