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.
I experienced this same problem before too. The security system could be the problem. The imobaliser shuts of the car if it thinks there is a problem with the ignition(if it was hotwired).
There are several reasons why a car will start and then bog down when the accelerator is pushed. Some of the reasons could be plugs, fuel pump, or the catalytic converter.
The problem could be a mechanical problem it is important to take it to the mechanic to have it checked.
If you have a 2003 Trailblazer which takes 5 minutes before it starts, there could be a problem with the remote start or the ignition switch.
Could be several things but more than likely your fuel pump is bad.
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
it could be the throttling positioning sensor
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!
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.
If your 1999 Acura TL starts well but develops a problem when you accelerate, the problem could be with its transmission.
Try Putting It Into Gear!!!!!
Could be a vacume leak or a sticking clutch or accelerator edal or cable. Timing could also be a problem. I advanced my ignition timing just a little bit and the problem went away.
