Weak fuel pump?
Hi.I,ve had a starting issue for yrs. on my 94 Z.I have to turn key on & count to 3& make sure i hear fuel pump cycle.Failure to do results in car not starting.I hooked up a fuel pressure gauge& got the following:44 psi,key on,pump running,45 psi(no vacuum),38 psi(14 in vac.),36 psi(motor running),37 psi(key on,engine off),Fuel pressure rose after a couple mins. to 44.I checked the fuel pressure reg.& it held pressure.I have a MSD Opti,MSD 6A,& MSD Coil(just installed).I have a MAF+ Translator & leaned out the fuel 2%& had rebuilt/flow benched 24 lb. inj. installedin 2013/14.Car has no drivability issues/high speed issues.Pl. advise& thnx for any advice..Darren
