I am trying to get a 2001 cavalier running for my uncle. He is dying and wants to sell it. It hasn't been started in a few months. The batt. was dead, so we had to jump it. I can hear the fuel pump kicking on and off when I turn the key on, so that's not the problem. The dash has a Security System light, but I don't know how it works. The manual just talks about a keychain style that didn't come with the car. The book mentions a Passive anti theft device, but gives no further information. We may have triped that while jumping it. It will run if we squert gas into the intake. I tried to press down the valve on the fuel line, but I didn't see any signs of pressure. The only thing I can think of would be the fuel filter, but it should at least fire even with a plugged filter. I don't know if they are equiped with an inertia switch for crashes or not. I really need to get this running. He needs to sell it to help pay for his final costs. Thanks in advanced. :confused:

Old gasoline is bad, replace with fresh gas or dilute it if there is little enough in the tank.

a fuel filter is $10 man try it. when they clog up then they clog up lol.
