Question about 1991 GMC S-15 Jimmy
I HAVE A 1991 GMC JIMMY WITH A 4.3 THOROTTLE BODY . (TBI), IM HAVING TROUBLE WITH IDLE AND STARTING, WHEN I SHUT ENGINE OFF OR IT QUITS, I CAN HERE FUEL DRANING BACK INTO TANK, IS THIS NORMAL OR DOES THE FUEL PUMP HAVE A CHECK VALVE BUILT IN TO IT THAT IS SUSPOSE TO PREVENT THIS.
The fuel is in a continous loop being available at all times to the TBFI. It has the return path so it can always return to the tank via the return line. Np check valve as the pump runs all the time.
