What do you check if your 1994 31 TBI is not spraying fuel?
Ronnied2000
THERE IS A FUEL VALVE TOWARDS THE BACK OF THE ENGINE THAT SHOULD HAVE PRESSURE IF THE FUEL IS GETTING TO THE FRONT. THERE ARE RELAYS FOR THE FUEL PUMP ON THE PASSENGER SIDE UNDER THE HOOD BY THE WINDOW IN A BLACK PLASTIC BOX. CHECK THESE TWO FIRST . IF IT SPRAYS A LITTLE TRY SOME BERRYMAN B-12 PART # O116 IN THE GAS TANK (IT SAYS FOR OIL TOO BUT IT CLEANS TOO GOOD FOR OIL) IT IS THE BEST AND HAS SAVED MY CUSTOMERS LOTS OF MONEY INSTEAD OF REBUILDING THE TBI OR THE CARBS.
