Turn the ignition to the on position without starting the engine. you should hear the fuel pump running for 5 seconds inside the fuel tank. if not heard replace the engines oil switch. that starts the pumps circuit when the key is turned on. after the engine builds up its normal oil pressure the computer shuts that oil switches circuit off and turns on the fuel pump relay

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.

Where is the fuel pump relay switch on a 1988 Ford Crown Victoria 5.0


The computer controls the injection of the fuel. If you look at the wiring diagram you will note the bottom 4 pins that are the negative and positive to the left and right injection. Atleast on my 1991 it is .Could be the ecm or computer is sending a false signal or not sending one at all. A sign of this is the fuel pump in the gas tank can be heard and will continue to run as if pressure in the fuel system is not building. Tthe truck want crank as if no fuel. When starter fluid is injected into the Throttle body the egine will start and run untill fluid is used up. It will keep running as long as fluid is added.

88 gmc s15 wont stay running after it is warm


Did you check the fuel pressure before you replaced the pump ?
Can you spray carb cleaner or starting fluid into the throttle body and make the engine want to start ?
If it is throttle body injected, can you see the fuel spray when you crank it hot ?

1987 chevy with Throttle Body... You literally have to put it to the floor to get it to start, then it'll run nice for a while thinking it'll run take it for a drive and it will shortly die on


Check all fuel lines for leaks, make sure it doesn't have bad gas in it. Listen for fuel pump when key is turned on. Change fuel filter. See if that's helps.

Start-die start-die on hot re-start usually after 2 hour hot soak


8 - 9 psi is too low for throttle body injection, locate and replace the fuel pressure regulator.

1988 iroc-z 350 tpi - runs poorly when hot (190-200degrees)


Does it run poor at full throttle or between quarter and half throttle? Does it hessitate? If it does the EGR valve may be worn out. I had an 87 transam with TPI and was having problems with it stumbling and hesitating when it was warmed up. If the car starts hard and you have these problems then the issue may be low fuel pressure. Hook a guage up to the fuel rail and make sure you are getting pressure. If you are only getting a few pounds of pressure it may be the fuel pump or fuel pressure regulator. Good luck and if you thought this information was helpful please rate it when you get a chance.

Thanks - Tech101
