I have a 93 saturen sl2 4 door twin cam engine and it starts up ande runs for a second and then dies and i dont hear the fuel pump running what is wrong with it

Just because you can hear the pump run, doesn't mean it is supplying enough fuel to properly operate the injectors. You need to check the fuel pressure at the fuel rail. If you have at least 45# of fuel pressure at the rail, you need to make sure that the injectors are metering. If memory serves me, I believe they are fired by the pickup in the distributor, but 93 is right when they were phasing into DIS ignition.

storm what engine? 4xe1 or 4xf1 SOHC or DOHC (twin cam)?
its really an Isuzu Impulse in snack skins (badges)
does test fuel run engine? that is step 2.
if the cam timing belt slips, the DOHC goes boom.
the SOHC engine belt slip,cause no starts, due to huge
compression drop, and fails the test fuel tests.

SOHC, keyon, 30-46PSI
same for both. engines
but as all mPI engines it drop running at idle.
and rises at WOT> (FPR actions most work right running) ask
but its no running
ever do a 60,000 interval tuneup with a new cam belt.
no?

It should at least run for several seconds after you turn the key on. It MAY run longer, but it SHOULD run for several seconds. If fuel demand goes down (engine not burning much fuel), the pump may not run after that.

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.

Before starting the engine, the fuel pump should only run for a few seconds when the key is first turned, to pressurize the fuel system. Even though the pump appears to be running, you may either have not enough or too much pressure for the engine to keep running (fuel pump or pressure regulator). I think it may just be a coincidence the engine quit while turning a corner, but the gas in your tank may have been so low it sloshed away from what is likely a very old pump, starving it and causing it to failure.

do you hear a pump noise when you turn the key to the run position? do this with the door open if no sound check fuses if good pump could be problem . if sound heard try fuel filter.

get into car with windows up close doors so its quiet put key into ignition turn key to on position do not try and start it. when you turn the to on position listen you should hear a hum noise from the fuel tank that will be your fuel pump working the hum will only last about 2 to 5 seconds if you dont hear a hum could mean fuel pumps noy working.

only half way there if you have a tbi check the crank sensor/ cam sensor that is the first line of business on that truck if the crankshaft sensor fails the truck stops dead when you wait a few minutes the sensor re energizes and the truck will work again for a bit antiknock can cause similer problems but not while the truck is running

sounds like your fuel pump has retired on you,running you car low on gas is hard on pump,they are cooled by the gas an are lubercated by the gas, I hope this helps you

i have 2 keys for my passat.with 1 key the engine runs perfect and with the other key the engine runs 2-3 seconds
