QUESTION: well i hard wired the fuel pump to the battery for temporary so i could rule it out as a suspect, and the fuel pump and actually the whole tank came right out of a running driving truck, i also pulled the fuel filter and just put a piece of fuel line in its place so i could eliminate that as a suspect as well i have pulled the regulator off the fuel rail and kicked the pump on and fuel is traveling through it so I know theres fuel to the intake i also have changed the t.p.s., the i.a.c., and the m.a.p. sensors, with no luck, the only thing left is the injectors that i can think of but other than that im feeling pretty retarded, especially since i have been a mechanic for 15plus years lol It has a 2.2l 4cyl in it
ANSWER: HI SHANE,WOW YOU WANT TO A LOT OF TROUBLE CHECKING FOR FUEL PRESSURE AND VOLUME >>> OK WE KNOW FOR SURE IT IS A FUEL PROBLEM [NOT GETTING TO THE INTAKE SYSTEM]PRESSURE IS OK, AND NOT IGNITION..SO DID YOU CHECK ALL OF YOUR FUSES TO THE PCM AND INJECTOR DRIVERS AND RELAYS.. IF ALL THE FUSES ARE ALL OK THEN I AGREE WITH YOU THAT THE INJECTORS ARE NOT OPENING UP..LETS CK FOR PULSE, GRAB YOURSELF A SIDE MARKER LIGHT BULB #194 TAKE AND LIFT THE METAL TABS STRAIGHT OUT AND REMOVE A PLUG CONNECTOR TO ONE OF THE INJECTORS,NOW PUT THE LIGHT BULB PLUG INTO THE HARNESS FROM THE INJECTOR AND HAVE SOMEONE CRANK THE ENG WHILE YOU WATCH FOR A PULSE ON THIS LIGHT BULB. WE WANT TO SEE ON,OFF,ON OFF,ON OFF ALL THE WHILE THIS IS CRANKING..IF NO PULSE IS FOUND THEN WE HAVE A PCM PROBLEM OR WIRING HARNESS ISSUES..DOES THIS BY CHANCE HAVE AFTERMARKET ALARM SYSTEM,CK TO BE SURE !!!! SOME ALARMS SYSTEMS REMOVE THE INJ'S FROM THE PCM TO STOP IT FROM STARTING,JUST A THOUGHT. LET ME KNOW HOW YOU MAKE OUT AND IF YOU NEED MORE HELP,LET ME KNOW. ALSO PLEASE WHEN LEAVING THIS SITE, RATE MY ANSWER,THANK YOU,,, TOM..

QUESTION: Thank you, I will hookup a noid light and check, im thinking they may just be plugged to an extreme that its not allowing fuel to pass through, the one thing I forgot to tell you is that my boy who drove this truck for 3 yrs before I bought it works at a scrap yard and was running scrap yard gas in it so it wasn't the cleanest fuel around, maybe that stuff from sitting for 4 months without being ran hardened right up in the injectors and plugged them off, its not equipped with any alarm system.. I would really like to thank you for your time and help, i really appreciate it, where you from btw?
