Gotta' love a Canadian BOOB man--I work with a bunch in Winnipeg--cheers!
Yeah-I've probably been remiss 'bout draining the fuel filter but it fires right up up--it's definitely something with pushing the dang clutch in after the first gear engagement. I will change the filter as it's due anyway.
Could be a bare wire somewhere, the mice chewed up the vaccum lines in the heater system last summer and I still have this scheduled to repair but it seems odd that it would work with the first gear engagement and then die with the next clutch push.
The problem became apparent after I recently removed the aft fuel tank as it was leaking due to corrosion. Don't use a power wire brush to remove the mastic Ford uses to attach the stone guard plate to the tank--it makes a big mess.
After removing the tank, I used the tried and true Red Green solution and duct taped the fuel lines and other connections together for the three day period it was without aft tank. It was during this three day interval the problem became evident. I thought maybe the fuel system was somehow sucking air although there was about half a roll of tape securing the open ends. As luck would have it, the local O'Reilly had a (made in Canada no less) tank in stock, which we installed last weekend only to find the problem still existing with the clutch. Engine seems to run fine off the new rear tank as long as you leave the clutch alone.
The clutch switch wiring harness has four wires and four connection pins on the switch, two of which are the starter lockout--I'm not sure what the other two do but I'm beginning to suspect a computer problem as opposed to a mechanical issue given the wierd nature of the problem. I will try the light on the fuel solenoid to see what is happening there.
Thanks again for the interest and comments.
