Hey Craig,
The Bonco II finally got to the point that it would die any time it was put into idle. Changed out the fuel filter and for some reason the thing was purring like a kitten for a week. Problem solved? Apparently not. This afternoon...same thing. Checked the fuel pressure when I did the filter and it was approximatly 38 psi, which is what I believe it should be (of course this was after it had decided to start running again). The relay is also working fine. ???
Would a fuel pump just intermidently not work? Don't know if this sais anything about the pressure sensor, but the low fuel light has started to come on every now and then, even though the tank is full.
Any further help would be gratefully appreciated
Thanks, Rion

No 'clicking' when you turn the ignition on and no starting (but engine turning over & spark) suggests that the fuel pump, probably the high pressure pump, is intermittently not coming on to charge the fuel manifold. The problem could be as simple as a plugged fuel filter (pressure in the line still), the pressure sensing unit (the unit itself malfunctioning or just a bad/intermittent connection) or the fuel pump itself (again the pump itself or a bad/intermittent connection). I'd replace the fuel filter first (cheapest), and you may want to cut it open to see if it is plugged. If that doesn't work, try replacing the fuel pressure sensor then the high pressure fuel pump.
