my 95 Buick roadmaster starts up an shuts off. i changed the fuel pump the fuel filter is fine. can anyone tell me what might be wing????
Spray some starting fluid in the intake to see if you have a fuel or spark problem.
I did that and it does the same thing before and after changing the fuel pump
fuel pump pressure is fluctuating perhaps down to zero-
there has to be a way of testing the output of the fuel pump.
Doesn't this design have a fuel rail with a shroeder valve on it?
fuel pressure regulator?
What's going on with the fuel delivery?
may be a security issue
Jimmy seems to think that your security is shuttin' you down- Do you have a fancy ignition key?
Yup the one with the chip
right on Jim, does this problem exist, even when this key is used?
Yup both set off keys I have has chips in them
