Once you turn the key on it runs for one second & then quits.Is there a fuel pump sensor that could cause this or is the pump going out. free flowing & under pressure

Only a guess as you don't state model or make. If you are testing fuel pressure at the throttle body you have a TBI system.
The ECM controls the fuel pump by allowing a short run time to prime and then requires oil pressure to keep the pump running.
If you are testing with out the motor running you are only getting the prime signal.

1998 honda civic. car wouldn't start. thinking need gas. get gas. prime throttle body (maybe a little too much accidently) however, waited a day.(battery was dying from all the attempted starting. put an...

The only matter there should be in the throttle body is air. The throttle body in no way has anything other than "nothing" in it. The liquid you see could be the gasoline you threw into the throttle body.

Getting back to your problem. Do NOT have someone looking down the throttle body while you are trying to start the engine. That person may receive a haircut he will never forget! Get the battery charged. Try to start the engine because even though you think you put too much gas in the throttle body, it may start.

The tricky part. If the engine starts and runs for a few seconds, then you are having a problem with fuel delivery and that is the fuel pump most of the time but not always.. If it does not start at all, try one more time to pour gasoline into the throttle body, hold your foot about 1/2 way down on the pedal and then try again to start it. If it still doesn't start, it's time to check for spark.

Hello! Change the Fuel Pump Relay...The prime contacts are defective..They are single pole double throw and normally closed for several seconds to prime the pump and then swing open applying battery to the fuel pump on the normally open side...The chatter is that set of contacts not breaking free from their normally closed position...The result is a unprimed fuel pump (which you are priming with gas into the throttle body....That plus the noise...Guru...saailer

Run out of gas and need to prime fuel to carburator

The way to prime the fuel pump is to turn the key on.This will make the pump run for 2 seconds then turn off.Shut the key of for 10 seconds then turn it on again.You may have to do this a couple of times to get the fuel to the throttle body.Also when you turn the key to the start position the pump will run til you let go of the key.Hope this helps.Good luck.

No fuel to throotle body truck will not start. Only start if prime the throttle body then shut off

you can attempt to run it w. starting fluid to make sure the engine is running aside of fuel issues. You may need to replace the fuel filter/regulator if it is a single piece. If it's definitely not getting fuel, its either a pump/filter/regulator issue, or an electrical issue. You can generally hear the fuel pump running when the engine is on if you are close enough to it. you can almost always hear it prime. if all is good and the fuel pump can be determined to not be at fault, change the filter and try again.

Engine wont start without priming with gas first, then runs well

i have the same problem on a 98 jimmy 4.3 4x4.
i replaced the fule pump and have good pressure.
new wiers & coil (good spark) no MIL & no codes.
will only start when primed. it will run & drive all day
with no problems.
but once it has been turned off (warm or cold) i will
have to prime it once again to start it.
i have another engine that was in it before it spun a bearing.
it ran fine so i know all parts are good.
i swaped the mass air flow and throttle body but i still have
to prime it everytime to start it. am i forgetting something?
should i swap out the intake with the injectors?
any help would be sweet. thanks.

Cranks, fuel pump is running, but engine will not start without priming Throttle Body with gasoline, then starts immediately.

Have you Replaced the Fuel Filter Yet???? How long does it run when Primed? Does it just Burn what is in the Bowl and Die?
