Question about 1993 Chevrolet C1500

1 Answer

When I start my truck up it will die after 1-3 seconds like its not getting enough fuel, but if I keep the engine at 2000-3000rpms for 1 minute it will work just fine, but if I let the truck sit, shut off, for 5+ hours the same thing happens. I've replaced the fuel filter, but it didnt solve the problem

    Do you have a check engine light on? Your problem sounds to me to be more like a lack of air, rather than fuel. ie: air filter, mass air flow sensor, egr, pcv valve, ect.

I'd guess: not enough fuel flow. could be a fuel filter, fuel pump, fuel pump relay, fuel pressure regulator. No check engine codes? I would think there should be some that would help diagnose.

1994 Mazda PU Truck sometimes won't start if shutoff for 5-10 minutes.. Several tries later, it will start. spark seems ok, it gets enough fuel for a second, but then poops out. fuel pump shuto


Well there is no shutoff relay, but there is a fuel pump relay that powers the pump.
I would check it first. The computer grounds the relay for 3 seconds when you crank the engine to boost fuel pressure. Once the engine starts the pump is powered only if you have oil pressure.

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.

When my 1972 chevrolet 350 4 barrel is warmed up it acts like its not getting gas and jerks and eventually dies. if i wait a few minutes it will start up but after slight acceleration it starts it aga


Good chance it is not getting fuel, or enough fuel.
When the rig is cold, the choke is closed. As it warms up, the choke opens.
If the metering jets inside the carb are dirty, they may not be letting enough fuel into the barrels. You could also have a vac leak that is masked by the choke until the engine warms up.

Hard to start after it sits u have to keep cranking for at least 30 t0 45 sec


When you turn on the key the fuel pump relay causes the pump to run for one second to bring the fuel manifold presure up. If the vehicle has 'sat' for a long time, this one second is not long enough and so the engine is struggling to get enough fuel to fire. Try turning the key on and off every couple of seconds for about a minute, then turn the key to the start position. The engine should now start. Do not touch any controls such as the throttle, the computer will take care of all this.

Car will start for a few seconds then dies.


Still sounds fuel related to me. Getting minimal fuel enough to start & or rev, but not maintaining proper pressure required. Try this. Get a can of WD-40 ready, remove air intake hose at throttle body. Start car & when it starts to begin to die, spray some WD-40 into front of throttle body & see if engine continues to run, as long as you keep giving it squirts of 1-2 seconds. If it does, change fuel filter first, but be prepared to do pump too. If you can get a fuel pressure test done on it, that would be even better. Let me know what happens.

Car will start then die after a second


Are you certain that its a fuel delivery problem? Since it DOES start and then Dies...i would look into "Cold Starting" problems.. Like a Coolant Temperature Sensor -- it acts like a choke for these newer cars. Next time you start it...rev the engine and try to keep it running for a few minutes.....see if it stays running after you get the engine warmed up....if it DOES stay running...then thats the problem. Otherwise try to get the trouble codes from the OBD2. you can usually rent or borrow them from your local Auto parts stores. Keep me posted and i can help you figure this one out.
