Battery was replaced and then the fuel pump since the old one was not providing any fuel plus, once I got to it, one of the hose connections had rusted through.
It now starts, but rough. Service engine soon light blinks after a couple minutes (running rich). Liquid which seems like just water comes from the exhaust. I have not been able to get it up to temperature since I started this.
Fuel pressure was checked, after fixing a bum gauge. Using the pigtail on the side wall to run the fuel pump, I am getting 70 psi, 66 or so when running. The fuel pressure does not hold when the pump turns off. I opened up the intake and expected to find a leak but I did not. I still replaced the regulator, but not the entire spider. I crimped hoses and neither stopped the bleed down of fuel pressure, but crimping both seemed to slow it down.
No leaks seen anywhere in the fuel line. I even pulled out each injector to look for leaks, none found.
I replaced the cap, rotor and plugs, the wires look brand new.
When it runs, there is a 'tick' that is in relation to RPM (higher RPM = faster ticks).
The fuel pump was not an AC Delco, but the chain store's stock. I am not confident in the fuel pressure gauge.
I have not touched the fuel filter because the pressure is good. I know the gas is old, but seems like it shouldn't be this rough.
Ideas? I am considering the following: spider (just because it fails all the time, but I have already replaced the FPR). Maybe a faulty fuel pump? Other?
have the same problem?
