My brother has a 305 in a Caprice that he just got started. Problem is, it will start but when you tap the gas the engine dies. Is this a fuel related problem?

Could be. Try holding your hand over the choke horn or choking the carb, see if that helps. More background info equals more help from the board members.

Could also be related to a vaccum leak and/or timing. Is it popping at all?

 

[adb2f]

To my knowledge, it is not popping. I will ask him to check to make sure all the vac lines are hooked up. I will also find out as much more as I can about it.

If it's been sitting for a while, it might need some fresh gas & clean spark plugs.

Doc hereimp:

Is this a Carbed or TBI engine?

If Carb, What type? Q~jet? If so look at the primary Pump on the q~jet...It may have dried up and cracked.

there is no pooping and it idles fine so that tells me there isn't much of a vacuum leak. The car has probably sat for 3 months. Changing the spark plugs now but would that really make a difference if the car idles fine? The accelerator pump could be it. Maybe it's binding or something. I'll check and get back with you guys. Thanks.

Oh and it is a Qjet.
