I did a coolant flush on XR2 and it was running great. Went out next morning, it wouldn't start. I thought the water I got into the open VAF shorted it out. So I got another VAF and it started, barely. Sputtered the whole time it was running. Took VAf off to do the VAF hack as I am running a blow through setup. It won't start again. I swapped out computer and found a little corrosion on one of the pins. I cleaned it up, but still no start. It tries to but won't "catch". I have installed a new cap, rotor,Jacobs wires, Jacobs coil and copper core plugs. I will reset the VAF back to where it was and try again. Any other ideas? Dizzy pickup, ground wires, TPS, etc.....
I did a search for this problem and everytime it looks like the thread is leading into something it gets hijacked and goes into a different direction.
