Fuel related. Car will not start unless you crimp a fuel line to stop flooding. If you crimp a fuel line it will start and you can get it to run by adjusting the pressure to allow more or less fuel. Is this culprit going to be the regulator on the plennum?? This is my first thought at least.
Reg or maybe badly leaking injectors. You'd have about 345 spare regs from when you where playing wrecker wouldn't you?
I think I have a spare reg let me know if you cant find one and I'll hunt through the stockpile of parts I got ripped off by, from an obnoxious letcherous old bastard. There also was an alledged 'incident' involving this individual and a forklift but I cannot say too much as there was a non-disclosure clause in the court settlement.
