Since it is a older car might invest in wires, plugs,cap and rotor, then set the choke on the probably Rochester 2 bbl. the knock you hear might be a lifter that has lost its prime, another words once you get it running for a few minutes it will prime up and stop clicking

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.

Ford expedition 2007 engine crank but wont start and engine light blinking 8 times


You will need to do some testing here to find out why truck will not start,
this may be a bad fuel pump but lets check, a quick test is to spray starting fluid into throttle body. you will need to remove the intake boot to get to throttle body to spray, you will also need to open throttle plate with finger . with plate open spray fluid for 5 sec, then release the plate and put boot back on and try to start truck. if this is a fuel problem then truck should start and run for a few seconds and then die out. if it does this then i would say the fuel pump is bad,

A quicker test is to have someone banging on the bottom of the tank while someone to trying to start it, and if it starts then pump is bad, this is not a definite way but a quick way, try this first and then starting fluid. good day.

1985 corvette cranks but won't start, fuel pressure good, oil is good also, it doesn't seem to be geeting any fuel. New fuel pump, filter & gas. Is there a security aystem problem?


Check to see if you have spark, if you do, and still it does not start, then you may think that fuel is not getting to it. At this point, use some starting fluid and spray it at the throttle opening. That should start it for a few seconds and give you the answer.

1989 pontiac firebird 305 v8 starts and idles


Your idle air control valve may be dirty or the wire harness may be damaged. First try cleaning the throttle body with throttle body cleaner and make sure you use all the can up and try to get the idle air control valve cleaned. A faulty or dirty idle air control valve will cause engine to stall when put in to gear from idle. Good luck and hope this helps. Keep me posted, be glad to help you get your car running 100% soon.

My 2001 new Beetle will not stay running. It starts up, then 5-8 seconds later will sputter out and die. If I pump the gas peddle a bit after it starts, it trys to stay running longer but then sputters out...


Hi There,
Try this: You will need 2 people - Have someone Spray Starting Fluid in the throttle then start the car and have someone spray the fluid continuously into the throttle. If the car continues to run you have a fuel problem, but if it stalls out, replace the coil pak. Hope this helps and thank you for using FixYa!
