Question about Jeep Grand Cherokee
Engine 4.0 Injectors 1 & 5 stay open. What exactly causes that to happen?
If not pulsing, could be a bad pcm. The computer grounds the injectors internally for a split second to pulse them . If trash or debris is not making them stick open, buy a "noid light" for checking injector circuits. Plug it in to #1 or #5 and crank engine over: if circuit is working right, noid light will be blinking. If light is on steady, computer is not interrupting ground to cause pulsing.

BEFORE CHANGING THE INJECTORS, TRY REMOVING THE HOSE THAT LEADS TO THE THROTTLE BODY AND CLEANING THE THROTTLE BODY AND THROTTLE PLATE. USING AN OLD TOOTHBRUSH AND A CAN OF CARB AND CHOKE SPRAY, SCRUB IT, WHILE WIPING OFF THE CARBON WITH A CLEAN CLOTH RAG. THIS SHOULD HELP IT RUN CLEANER AND WITH LESS MISSING. SPRAY A LITTLE CARB AND CHOKE WHILE THE ENGINE IS RUNNING AND KEEPING IT AT ABOUT 2000 RPM'S. HOPE THIS HELPS. PLEASE KEEP ME POSTED. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. GOOD LUCK

Hi, you have to remove the fuel rail and then remove the electrical connector and then there is a clip that holds the injector to the fuel rail remove that clip and then remove the injector

YEP REMOVE TOP ENGINE COVER AND DISCONNECT INJECTORS ELECTRICAL CONNECTOR,REMOVE FUEL RETURN LINE FROM INJECTOR, REMOVE FUEL INJECTOR HIGH PRESSURE LINE, REMOVE FUEL INJECTOR RETAINER AND RETAINING BOLT,THEN REMOVE FUEL INJECTOR FROM THE CYLINDER HEAD. YOU NEED A FUEL INJECTOR EXTRACTOR TOOL 9075A ON TO INJECTOR AND CYLINDER HEAD.YOU DONT HAVE TO REMOVE THE ENGINE.
