In a few seconds after the engine first starts, your ECM (computer) looks for signals from your engine oil pressure sensor, ignition circuits and possibly other sensors before it will allow the engine to continue to run. This is for both safety and engine protection. In an accident, the fuel pump is automatically disabled if your engine stops and you lose oil pressure. Likewise, you don't want the fuel injectors to be pumping gas into the cylinders if there's no spark (ignition) because the excess fuel washes lubrication off the metal cylinders and pistons which can damage the engine. A shop scanner should display the ECM signals and report an oil pressure or ignition drop out that is keeping your engine from continuing to run. The initial start mode runs the fuel pump by default for 2 or 3 seconds, but then the ECM has to hold the fuel pump relay in or it will drop out.

If the lights dim or go out when trying to start the car, you may have a low battery caused by dirty/corroded battery terminals and cables. That would also explain why jumping the battery doesn't do any good. You could also have a bad ignition switch which isn't sending power to the starter solenoid. Another cause may be a bad starter solenoid, corroded wire at the starter solenoid, or a bad neutral safety switch if it's an automatic transmission. Try holding the key in the start position while moving the shift lever from park to neutral and back and forth a few times to see if the car trys to crank over.

Agree - blocked fuel filter, or intake manifold problem. Could also be a vacuum leak, PCV or EGR valve issue!

Have you tried the fuel filter? Also check on the vacuum system...

try having a shop plug a scan tool into the car and see if there are any codes being set when you try to start it this is where i would start

Does your car have a carberator or fuel injection?

Sparkplugs, possible. Just had a friend with that same problem.

Have you checked the belts and the engine? They can be troublesome
