Well ,it is a 2000 chevy blazer 2 door, i put a new fuel pump,and fuel filter,and it still will not start,if you put gas in the carburradtor it will start for a second then it dies,what could be the


Did you verify that you have proper fuel pressure? Should be around 60 PSI. If pressure is low, ensure that fuel filter is not installed backwards. If fuel pressure is OK, check your injectors with a noid light to see if you have injector pulse. If the truck starts with gas poured into the intake, it is NOT the spark plugs causing the problem. You are chasing a fuel delivery issue, NOT a spark issue.

Marc,
this shows that the oxygen sensor on the left exhaust pipe before converter is bad,
And the front oxygen sensor on the right exhaust infront of converter is bad.

I have a 1996 chevy blazer replaced the fuel and


No, the fuel pressure valve may be stuck open so that the fuel pressure is too low when you start up, but the pump keeps up after the engine starts...
The fuel pressure valve is draining the fuel back into the fuel tank when the Blazer is parked.

2000 Chevy Blazer Cranks but wont start...


What about the fuel filter????? Have you changed it out??? If you can spary something like a started fluid, that means it is a fuel problem. My last check, it has to be above 50-psi on the fuel pressure to make it run right. I had 35psi, but whould not get over 30mph or down hill maybe 45mph. Check both filter & pressure, but check pressure with a New fule 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.
