I've been having some intermittant starting problems. It'll crank but not turn over, once I hit the gas pedal to the floor it'll sputter and then eventually fire up. Once started it runs fine. I'm throwing code 17 which is 'engine is running too cold' but I think that is from an unrelated problem (my temp gauge is not working) which I had long before the starting problems.
The fuel pressure is about 42 psi in the on position and 49 running (its a '96). I tried leaving the pressure gauge on and turning it off; when I came back to check it an hour later, it had dropped down to 38 (so I lost roughly 4 psi in an hour). The FSM doen't say how much pressure should be lost so I don't know if this is normal or not. Should I try leaving it overnight maybe? How much pressure should be left in the rail when its been off for a few hours or overnight?
Also, if I need to do the BMW check vavle fix, where in the fuel line should I put it?
Thanks
