This group has helped me in the past when the VW forum had let me down so i hope no one minds, i'm kinda' desperate.
My 95 cabrio developed some bad noises and I happened to have a 97 cabrio with a good engine so i paid a guy to do the swap.
He's a very good mechanic with experience in just about everything except European cars.
He swapped the intake and everything else that was unique to the 95. It's all back together and he can't get it to start.
We're not hearing the fuel pump come on.
As the car started an ran OK before we assume the problem is related to something during the engine swap.
Any suggestions?
Is there a simple way to jump the fuel pump and force it to run?
THanks

I don't believe there is any kind of pump reset.
And i assume (dangerous word) that all the obvious electrical things have been checked. This is a pretty smart guy.
The specific quesion is this; does anyone know if the fuel pump runs constanntly in this system or if it uses a sensor to cycle it on and off.
These euro (Saab, Audi, VW) sytems are similar- bosch fuel pump and either pressure regulator or a pressure sensor that cycles the pump on and off.
THe difference makes trouble shooting, or jumpering MUCH easier.

OK, i hot wired the fuel pump and then we learned we have no spark.
So, what connection or component would lock out spark and fuel in the context of an engince change?
I bet it will be simple when the answer surfaces.
thanks

Remove the positive battery cable, let it set for 5 min or so, then
re-attatch it. Be very sure that all accessories are turned off, and the
doors are closed, trunk also. If you have an underhood light, take the bulb
out. This will reflash the computer. Sounds like you activated the anti
theft software. If not this, notice that I said positive cable, not
negative. It has been quite a while since I was at Porsche/Audi school but I
think that is how you do it. If you have VW's scan tool, it will do it too.

If you need a scan tool, the generic ones do not really scan the VW cmputers very well. A common interface for VW Auto Group (VAG) cars is commonly refered to as a "VAG COM". There are clones but the "real" ones are from Ross Tech.

VCDS will work with most Volkswagen and Audi models sold World-Wide 1994 through 2010. It will work with some cars all the way back to model year 1990. It will also work with most late-model SEAT, and Skoda models sold in markets other than North America. If your VW or Audi has a 16-pin "OBD-II style" Data Link Connector, VCDS will definitely work. If your car has the old "2x2" Data Link Connection, check if there is a wire going to each pin, as shown in the picture. If there are four wires, VCDS should work with any diagnostics-capable modules that are present. If there are only three wires, then nothing in the car is diagnostics-capable...

I have a USB one and an older serial cable one. But there are other people who will share: (reminds me of the black list.)
