My 1991 Chevy G20 van has been sitting for 8 months with a full tank of gas. Try start but problem. Will run if I pour gas into carb - pump working and injectors drip and do not spray. What should be the fuel pump pressure to injectors?
Gasoline is entropic. Eight month old gas is suspect. But if the injectors drip and won’t spray, it doesn’t matter about the old gas. You have clogged or bad injectors. replace them.
FYI – PROBLEM HAS BEEN RESOLVED!!
GAS WAS NOT THE PROBLEM, IT BURNS! INJECTORS WERE NOT THE PROBLEM THEY DRIPPED ONLY!
PROBLEM NOT ENOUGH PRESSURE COMING FROM FUEL PUMP — FUEL PUMP WAS NOT THE PROBLEM!
PROBLEM WAS "HOLE’ IN TWO INCH PIECE OF HOSE CONNECTED TO PUMP!!
TO GET THIS SPECIAL 5/16 INCH ID AND 11/16 INCH OD PIECE YOU HAVE TO BUY THE WHOLE PUMP KIT!
REPLACED TWO INCH RUBBER HOSE AND ALL WORKS JUST FINE!!
THANKS FOR ALL THE HELP FROM YOU CAR GUYS!!
CHECK FUEL PRESSURE 1ST. IT WILL SAVE YOU TIME AND MONEY!!
