Engine Performance problem
1985 Cadillac El Dorado V8 Front Wheel Drive Automatic
I have a 1985 Cadillac Eldorado that wont start unless I spray starting fluid into the Throttle body.
I rented a fuel pressure gauge and it showed no pressure at all on the fitting at the line at the TBI.
When I turn on the key, fuel pump does run for a couple secs. Disconnected the fuel filter and checked pressure there as well, none.I cranked it with the line removed at the filter and fuel does pump out but not like I think it should, not very forceful.
Would this be a weak pump or a faulty pressure regulator.I have heard that these are known for ruptured diaphrams in the regulators. Help, I dont want to drop the tank and put in a pump only to find out im wrong. Dont have the money to waste. Any advise would be welcome.
have the same problem?
