Start and quit running I can spray gas in the throotle bottle and it will say running while I am spray it


Must be your fuel pump has quit working. There should be fuel under pressure in the line to the throttle body, just by turning the key to on, not start. Not real high pressure like in multiport injected engines. Throttle body injection runs on about 20psi. If no pressure in your lines, find out why the pump is not working.

2002 HD 1500 Chevroley 4WD 4 door truck engin lost power and died could start but when acelarated died max rpm 800 pulled filter turned key on pump shot a stream of gas 3 ft and stoped ran only secon


It is normal for the pump to run for two seconds when first switched on to pressurize the fuel system. It will turn on again when cranking and while running. I would still suspect the pump given your symptoms, however other problems could also give you the same symptoms. If it is the original pump from 2002, or more than about 7 or 8 years old, I would definitely replace it, and the fuel filter. Often the pump will go intermittent. I had one that I could restart and get down the road by hitting the bottom of the gas tank a few times!

YOU COULD HAVE RESTRICTED FUEL FILTER OR FUEL PUMP COULD BE FAILING. FUEL PRESSURE SHOULD BE 9 - 13 PSI FOR THE GAS ENGINE.IF YOU HAVE 6.2 DIESEL ENGINE YOU FUEL FILTER STOPPED UP OR YOU HAVE FAULTY LOW PRESSURE TRANSFER PUMP.YOU COULD HAVE FAULTY FUEL SOLENOID AT THE INJECTION PUMP.

99 gmc wont start


check electric fuel pump operation ( located in the fuel tank ). Occasionally a fuel pump will burn out when running out of fuel, due to the fact the pump runs DRY for about 30 seconds till the fuel stops flowing out of the injectors, the engine quits, simultainously losing oil pressure which FINALLY shuts off the fuel pump. Sometimes TOO LATE. Hope this helps
