Chevrolet Repair: astro van, astro van, power control module

Question
i have a 1999 astro van. and cylinder 6 is not firing we changed spark plugs injectors and spark plug wires. but injector 6 is not firing fuel what could the problem be?

Answer
HI JOSH,I AM CONFUSED WITH YOUR QUESTION,I WILL ASSUME THE IGNTION SYSTEM IS NOW OK AND # 6 INJECTOR IS NOT PULSING. THIS CAN BE FROM 2 THINGS,PLUGGED INJECTOR WHICH IF YOU REPLACED IT, THIS WOULD BE HARD TO BELIEVE,NEXT A BAD [POWER CONTROL MODULE]PCM,OR A BAD WIRING HARNESS TO THE INJECTOR. I WOULD CK FOR PULSE AT THIS INJECTOR. GET YOURSELF A 194 LIGHT BULB,PULL THE CONNECTORS OUT AND PUT THEM INTO THE INJECTOR HARNESS,CRANK THE ENG OVER AND SEE IF THIS LIGHT BULB FLASHES,IF IT DOES THE PCM AND WIRING ARE GOOD. NO PULSE,BAD PCM OR WIRING..IF I READ YOUR QUESTION WRONG GET BACK TO ME..I HOPE THIS HELPS YOU,,,TOM..
