Subject: BAD FUEL PUMP, RELAY OR SOMETHING ELSE?
HELLO ALL,
MY 93 TY' RECENTLY STOPPED RUNNING. IT DROVE FINE TO WORK ONE DAY. WHEN I GOT READY TO LEAVE, IT TURNED OVER BUT DID NOT START. I CHECKED FOR SPARK, IT LIT UP LIKE CHRISTMAS. NO FUEL, HOWEVER. I PUT STARTER FLUID IN INTAKE, THEN THE TRUCK RAN (UNTIL STARTER FLUID RAN OUT, 4-5 SECONDS). I CHECKED THE FUSES UNDER THE DASH, THEY ALL LOOKED FINE! SO, I FIGURED FUEL PUMP.
I PURCHASED AND INSTALLED THE WALBORO 255 PUMP. I LEFT THE STRANGE DAMPER DEVICE IN USE WITH NEW PUMP, I HOPE THIS WILL NOT CAUSE ANY TROUBLES! WITH NEW PUMP INSTALLED AND NEW FUEL FILTER, TRUCK STILL DOES NOT RUN. I FOUND THE GRAY WIRE UNDER THE (2) FENDER-WALL RELAYS, UNDER THE HOOD. I JUMPED THE GRAY WIRE TO 12V+ AND WITH FUEL LINE DISCONNECTED (IN FRONT OF THE FILTER), I OBSERVED THAT THE NEW PUMP DOES WORK! THE OLD ONE MAY HAVE WORKED AS WELL!!! THE PUMP SEEMS TO WORK ONLY WHEN I JUMP IT TO 12V+ WITH THE (GRAY) FUEL PUMP TEST WIRE. WHAT SHOULD I DO NEXT? I AM CONFUSED AND MYSTIFIED AT THIS POINT!!!!
I HAVE ALSO RECENTLY LEARNED OF A OIL PRESSURE SWITCH, I DON'T KNOW WHERE IT IS OR EXACTLY HOW IT WORKS! MAYBE SOMEONE CAN GIVE ME SOME INSIGHT HERE!
MY TRUCK IS NEARLY STOCK, I HAVE STG 10 IN 1 CHIP AND A 3" EXUAST ALL ELSE IS OEM. I DON'T RUN MORE THAN 17PSI , THE TRUCK ALWAYS RAN FINE BEFORE NOW!!!
