engine starts but stops immediately

engine starts but stops immediately....anyone know anything about this?

 

[wises4057]

does it just rev up high when you start it then just die? a little more information would be kind of helpful. like how long does it run for before it dies? or if it idles normal when it starts, or if it's idling erratically.

can you keep the car alive by revving it

More info Please!

Does it buck, cackle, missfire, pop?

Does it rev realy high then fall to 0 right away?

Do you have to crank it for a while to fire it up the 2nd time?

Can you rev it to keep it alive?

it starts very poorly nd while i rev it, it just dies like 2 secs later it doesn't rev high at all..the engine shakes and black smoke comes from the motor and the exhaust.and sometimes it pops, like it back fires..and it does take a few times till it start up..and i've checked my spark plugs and they are smooth black..it was fine before, until i replaced the fuel injector o-rings ### the old ones were bad and leaking fuel..it took me a few times till i got it not to leak..i did use oil on the o-rings..and once i got it all together and tried to start the car, thats what happens..someone told me that it might be my fuel ragulator, could it be that? or maybe my fuel pump? or fuel filter? vacuum leak? or connections? i've checked for connections, vacuum leaks and for any fuel leakin, found nothing..not sure what to do..### halp..anything might help..thanks

its your crank angle sensor...... its about a 200-400 dollar fix at the shops....

Sounds to me like you are incredibly rich for some reason and flooding the engine. The key is that it didn't do it until you put it back together.

Double-check all your sensor connections and anything else you've disconnected/reconnected.
