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).
The problem could be a mechanical problem it is important to take it to the mechanic to have it checked.
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.
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.
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
Could be several things but more than likely your fuel pump is bad.
possibly a problem with the torque converter locking up, or could be something as simple as a vacuum leak
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!
it could be the throttling positioning sensor
If your 1999 Acura TL starts well but develops a problem when you accelerate, the problem could be with its transmission.
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.
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.
check the spark plug ... do not start it by bushing the fuel pedal . just start it by doing nothing els ...
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.
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)
Had same problem and changed the ignitionmodule, problem solved and runs great
There are many reasons your navel may hurt when you bother it. You could be agitating it, or there could be a problem with it. You should get a doctor to look at it.
It is a common problem for shevy. Usually the Fuel regulator. Or for other vehicles it could be a dirty fuel filter
If it has a carburetor, it is the flush pump on the carburetor. If it's fuel injected it could be a lot of different things.
It could be however the purpose of the accelerator is not to produce ions but to accelerate them, hence the name.
i have the same problem. i have good fuel pressure and new filter. it could possibly be related to airflow sensor or vacuum lines.
There are several reasons why a carburetor would do this. The most common reason is that there is a clog, which could be fixed by cleaning it. Another common cause is a problem with the accelerator pump. You can purchase a do it yourself kit to attempt to fix the problem.
