2010 f150 wont start will turnover but no start cant hear the fuel pump start either


sounds like either the fuel pump relay or the fuel pump itself has gone out. check fuse panel first then check fuel pump relay. if those are good then check power leads to pump at tank and if you have power there then the pump has probably failed. hope this helps. Chris

So i change the fuel pump, not when i try to start it. it just turns over and wont fire. before it went down, it was shotting black smoke, running real shotty and would literally die upon starting or not...


first things first you should stop just throwing parts at a broken car its a waiste of your money...
first things first, check to make sure you have spark, then check the fuel pressure, can you hear the fuel pump working when you first turnthe key one with out starting the engine, also verify that you have power to the fuel pump. 90% of all fuel pumps replaced are missdiagnosis's. most of the time its the fuel pump relay. so check these things first before replacing anything else.

Turns over and over can hear fuel pump come on will start with starting fluid and runs great but when shut off for a little while wont start again only with starting fluid


If the starting fluid works then you have a fuel pump or a fuel pump relay issue. The fuel pump relay allows the pump to come on for about 2 secs and prime the fuel system. Once the engine starts then the power to the fuel pump runs through the oil pressure circuit.
If the car starts on starting fluid and then continues to run... I would lean toward a fuel pump relay issue. Hope this helps, Good Luck!

1990 geo storm wont start, no fuel, no stored codes.


can you hear the fuel pump when you turn the ignition key to start position??( you should hear it start then stop after few sec.) If not, this could be the fuel pump fuse,some bad contact in the wiring of the fuel pump or the worst case the computer.but if you do,unplug your main fuel line to the injector turn the switch to start position again to see if you have some fuel coming out.if not this could be the fuel filter or the fuel pressure switch! hope this will help you...lipak!..

1986 944 Turbo wont start.Just died on me going around corner,will start with starting fluid.


It sounds like you don't have sufficient fuel.
Do you hear the fuel pump turned on when you put the key on?
If it is not, need to check the fuel pump relay.
Jump wire at the fuel pump relay to to turn it on to see if Fuel pump is working
Need to check if the fuel delivered to fuel distributor in spec.
Jump wire your relay 60s to check how much gas delivered to the fuel distributor, by disconnecting the gas input at fuel distributor and catching fuel in a calibrated glass container. The gas quantity ml divided by 60 sec to have a flow ml/s. If this is not meeting spec then change the fuel pump. Good luck.

1996 silverado 5.7 vortec cranks but wont start. fuel pump, gauges, "idiot" lights, blinkers do not work. flashers and all the rest of lights operate. Just replaced coil and this happens


Had the same problem with my '96 Silverado with 350 Vortec. The truck would only crank. It would start if fuel was poured down the throttle body. Could not hear the fuel pump hum. Fuse was good, but could not hear relay click. Relay was good, Did some electrical wiring trouble shooting. Turned out that one of the connectors that clasp onto one of the pins of the fuel pump relay wasn't making a good connection, too loose. I just stuck a peice of wire into the connector and pushed the relay back in. Relay clicked, Truck Started. It's been more than 4 yrs. since I made that McGuyver fix. Still firing.

1987 4.3L starting difficulty


First off, I'm a great believer in the simple solution. If jumping the relay works, then replace the relay.

As far as a relationship between fuel pump operation and oil pressure, coincidence of operation.

If the new relay fails you, I'll need some more info:
  • Fuel Injected? If you turn the key on (not to start) do you hear the fuel pump come on for a sec then shut off?
  • Hard to start when hot, cold, doesn't matter
  • When it does start, does it idle ok? erratically? High? Won't stay running? Dies immediately?
  • Does it blow smoke? Black? Blue? White?
  • When driving, does it lack power? Stumble? Stall?
Hope it's the relay
