    Are there any air leaks or vacuum leaks in the air induction system? Make sure that there are no air or vacuum leaks between the MAF (mass air flow sensor) and the throttle body.

Try swapping out the fuel pump relay, if thats good try testing your ignition system components. Start with the module and coil pack. If they are ok check the crank position or cam position sensor (which ever applies).

Why when i poor gas in carb it runs and then a few mins later dies


Test the fuel pressure, if it's low or non existant, you have a bad fuel pump, fuel pump regulator, or clogged fuel filter. That car has a throttle body, not a carburetor. All fuel injected cars have throttle bodies

I have a 1993 Pontiac transport van and it will start up and run for 5 or 10 seconds and die


You may want to do a fuel pressure test to start. The pump could be defective. The fuel pressure should hold steadily and not decline with the pump off. If the fuel pressure falls, you either have a fuel leak, stuck injector, faulty fuel pressure regulator, or a bad fuel pump check valve. If the pressure holds at the correct spec, note the pressure as the engine runs and then dies. If the guage shows correct pressure, you can then move on ruling out the fuel system.

Chevy express wont start


Will it run for a short time if you squirt some fuel into the throttle body? If so, then concentrate on the fuel delivery system. Fuel pressure at the test port on the fuel rail should be at least 40 PSI. If not, look at the fuel pump, the pressure regulator, and the fuel filter.

My truck will not start. i have a new starter, alternator, fuel filter fuel pump, mas, air filter. any other suggestions. its fine once its started. i spay choke spray in it to get started.


I have had similar problems and had to replace the fuel pressure regulator. It's a major expense because it sets below the diaphram in the intake manifold. Ask your mechanic about it, it may be the issue. I would get about 30,000 miles between replacement, I've replace it 3 times since purchasing the 2000 chevy blazer new, first one was under warranty.
