It won't crank up and it sat up 2 years


No gas, plugged fuel filter? Turn on the key but don't crank engine, listen with door open towards gas tank. You should hear a click and a slight motor pump noise for a couple seconds. If not then your sending unit failed.

1985 F250 460 runs for 2 seconds but then dies


If it is a carburated engine it should have a mechanical fuel pump on the side of the engine, if this is the case it will only pump gas when the engine is cranking or running. Disconnect fuel line at carb, crank engine and see if it pumps gas out of line, if not check filter and lines from carb to tank for stoppage or bending but more than likely you will have to change fuel pump.

93 toyota pickup 4x4 it will stay running after I turn it on to start it up, it starts up then after a few seconds it kills


if I'm reading this right...
... the engine starts and dies within a few seconds.
... you jumpered the fuel pump test connector and it will keep running.
... you smell fuel after trying to re-start when it dies.

Disconnect the plug to the cold start injector. Even if you have an issue with the engine running then dying after a few seconds after doing this, if you don't smell fuel after disconnecting the cold start injector and try to restart it, the cold start time injector time switch may be failing.

Buy a can of starting fluid and have someone start the engine then spray short bursts of the fluid around all the intake fittings. If spraying the fluid in any particular area keeps the engine running, I'd start looking for leaks around that area.


It does sound like an AFM or COR issue considering it dies after a few seconds, but the fuel smell when trying to restart the engine may be a separate issue that needs corrected / isolated first.it will keep running.

1990 s-10 4 cylinder 2.5, 5 speed, throttle body injection, 120,000 miles won't start without stating fluid. Runs fine after started, I've changed fuel pump, filter, plugs. I appreciate any help.


My first question would be is the injector spraying when you crank it ?
The way its supposed to work, the fuel line to the tank should have about 10psi of pressure before you crank the engine. When you turn the key on the pump gets power for 3 seconds to boost the pressure. The pump stops working until the engine has oil pressure which takes a few seconds.
If the base fuel pressure leaks back to the tank, or the pump relay is not powering the pump, you won't have any fuel pressure or spray until you get oil pressure.

My 2003 cadillac want start but it sounds like it wants to what's the problem?


The problem is fuel related. Bad fuel pump, bad fuel pump relay or a leaking injector causing fuel pressure to bleed off when turned off. When starting the car up for the first time have somebody turned the key just to the one position while you listen to the fuel tank. you should be able to hear the fuel pump kicking on for a few seconds.

you have a fuel pump relay . Check to see if the fuel pump is humming when you turn key. check for proper ground for fuel pump. try spraying some carb cleaner into the intake then attempt a start. The engine will run for a few seconds, this will verify spark. corosion at the electrical connections is always a possibility. and lastly can you get the engine running by opening the throttle when starting?

Make sure your air filter is clean and you are using brand new petrol. If you left old petrol in it it may have clogged up the carb. It sound like no fuel is getting to the spark plug. If you have a rubber priming bulb, press it slowly and regularly to try and keep the engine going once you have it started on starting fluid. Good luck.

Have you checked the fuel pressure? Fuel pumps are a common failure item on those trucks. Pick up a cheap fuel pressure gauge and hook it up to the shrader valve on the fuel rail. With the ignition on and you should have 55-65psi. Even if it's a few psi below spec it could stop the engine from firing.Once you determine the fuel pressure isn't adequate make sure you have a good power and ground at the fuel pump. If that checks out, time for a new fuel pump module. I recommend only replacing it with an AC delco unit, I've heard bad stories about aftermarket replacements.
You could also spray some carb cleaner or starting fluid in the throttle body and crank the engine over. If it runs for a few seconds after spraying starting fluid in you know you have a fuel delivery problem.

No fuel delivery from the Brand new fuel pump and filter. 1988 Ol


The pump is only suppose to run for 3 seconds if the engine is off. It will only stay pumping if the engine is running so the circuitry seems to be just fine. You prabably just got a bad pump again. Its common for repair shop to put 2, 3, and 4 pumps sometimes before they get one that works. We find it very common that a gauge will malfunction and the real problem is you just ran out of gas.
