I am working on my friends car a 1992 Buick regal custom V6 3.1. I put a fuel pressure gage on it and it had 0psi. After changing the fuel pump we had 16psi. So then I changed the fuel regulator. Then we got it up to 18psi. According to the repair manual it should have between 40-43psi of fuel pressure. I took it back apart and put another fuel regulator on it and checked to see if the fuel injectors were leaking under pressure (or stuck open) they were not. I also used an air compresser to blow the fuel lines out and of course there is a new fuel filter and strainer on it as well. Also the manual said that the pump should put out 1/2 pint per 15 seconds. It put out (unhooking it from the filter in to a jar) one pint in 21 seconds. For the life of me I can not think of anything else that would stop the pump from reaching the required pressure. Anything that anyone can think of would really be appreciated. Thanks in advanced.
