I'm having problems getting my '84 TD van to start using a recently purchased used TD pump from a Golf. I had the engine running fine when I borrowed the pump from my '91 NA Jetta engine. Now that I have the TD pump installed, timed, bled out lines, etc, it starts up and abruptly runs to full speed every time. I have not allowed it to run for more than 1-2 sec due to the rising engine speed.
I'm just beginning to learn how these pumps work inside; is there something I can take apart to check further? Or should I just return pump to seller?
did you mess with any of the fuelsettings???sounds like max fuel out toofar,or idle intoofar ,,, :?:
Well, I went ahead and took the pump apart, and guess what, I fixed it! Turns out a spring had come off a cold start lever inside the cover, probably when I had removed a bent actuating plate off the lever's shaft to straighten it. Turbo van go!
