pumping probably isn't helping if the truck has fuel injection. extended cold crank times are often caused by a bad cold start injector or the control for the injector. also if there is no fuel pressure (i.e. a fuel pressure regulator that is leaking back into the tank as the car sits), it will take awhile to start.

Get your accelerator pedal checked, I had surging problems for 6 months and Ford could not find the problem, they finally replaced the accelerator pedal and the problem went away. The throttle positioning sensor seems to wear out in the spot that it is used most around 1800 RPM

What could be the problem if a car starts sometimes and the problem isn't the battery?

Could be the starter or ignition switch...does the car crank/turn over when you turn the key? If you just turn the key and it 'clicks' it might be the ignition switch. I've had this problem before, and it ended up being the alternator. HOpe this helps!

What is the problem when your car turns over is getting fuel and won't stay started when you take your foot off the accelerator?

it could be the throttling positioning sensor

Your 1998 Oldsmobile intrigue will not idle but will run OK if you keep the accelerator slightly pushed down what could be the problem?

I just had that problem. Starts for an instant and shuts off. Had to drive about 10 miles to home with my foot on the accelerator and my left foot used for the brake. It ran fine that way till home. When I stopped in the driveway it was just fine. May have been bad gas or something blocking the fuel flow. Running it at 60 miles per hour for ten miles cleaned it up.

Firstly, only push the accelerator down once before starting. Use a torch and check the sight glass on the side of the carby to see if the level of fuel is at the center. If not, then you will need a new'Needle and Seat' in the carby.

Why does 1998 Chevy truck turn over but will not start?

there could be a couple of things wrong there are two systems in every motor that starts it up fuel and spark the problem could be any part in either system. Or another common problem is the cataletic converter but this would have caused it to run like crap long before it wouldn't start (most likely problem is the fuel pump)
