2a] Can you hear your lift pump working? N
2b] Do you get a steady flow of fuel from the water drain (T-handle) ? N
2c] Loosen the inlet line from the IP – is fuel coming out (Lift Pump on)? Oil pressure comes up and no sound from the LP.
2d] Loosen an injector line and crank the engine - does fuel come out? Didn't try, on my lunch break._________
2e] Do you hear a vacuum (hiss) when you remove the fuel cap? Little bit, new fuel cap @ 277,000km___________

4] Stalling Issues
4a] Do you experience stalling only when hot? Y
4b] Does it stall under particular circumstances? (ie hit bump, or on accel) When idling for more than 10 Min.
4c] Does pouring cool water over the IP seem to help with restarting? Didn't try, started up with first hit with the key
4d] Is stalling momentary (engine recovers)? N
4e] Does SES light come on when engine hiccups? No engine hickup.
4f] Does cruise control quit working when engine hiccups? No engine hickup.___________
