Question about 1985 Chevrolet Citation
2.8 liter v6 with Rochester 2bl carb.
The car sputtered on a real cold winter day and barely made it home.Has not run since. I can spray starting fluid in the carb and it fires up and runs well until the spray is burnt off so it is getting spark. I replaced the fuel pump and fuel filter so the carb should be getting proper fuel pressure.
Q#1. How can I check the fuel pressure if the car wont stay running. Is there a way to fill the carb bowl with fuel (or check it) so it will run long enough to check fuel pressure.
Q#2.I had heard these have a mixture control solenoid on the carb and was wondering if this were to fail would it be enough to prevent the fuel from entering the carb so it wouldnt fire, or would it just run rough?
The filter you chg. an inline filter? Is there a filter in the carb.where fuel line connects, some had a brass screan in the carb. you can chk. the fuel pressure without it running, just unhook line at carb. put it into a plastic bottle or something to catch it and have someone turn engine over if it squirts out good thats enought for it to run they only put out about 6 to 8 lbs. of pressure. I don't think that solenoid would keep it from running, when it will run on either. but maybe if you unplug it and see what happens. It suunds to me to be a fuel dilivery problem, either something restricting the flow to carb. or you got a bad pump.
