Walbro 255 install issue - please help

[Novablue454]

I attempted to install the walbro 255 on my 90 TSi tonight, and now the car wont start. It all seemed like it went perfect too. I've searched and everyone is talking about taking stuff off the bottom of the car and the tank being under the back seat. Mine is under the spare tire. So i pulled all that out, disconnected the plug, and then took out the 6 bolts holding it in at the top. After i got the unit out of the car, I removed the stock pump, put the strainer, o-ring, cap, and spacer on the walbro, and popped it into the housing. I then disconnected the blue wire from the top of the pump housing, and connected the red wire that came in the install kit. I then disconnected the black wire from the housing and connected the supplied black wire to there. Then i just plugged it in and put it back in the tank through the top. I did notice some resistance putting it back in, but it still went over all the studs so i tightened it down. I went to start the car and it cranked over a few times then stopped. it blew the ignition fuse (30A) in the tiny box on the side of the battery. I replaced that and it did the same thing after about 10 seconds of cranking. So for the sake of experimentation I put a 40A in there and disconnected the plug going to the fuel pump in the hatch. Cranked for a good while with no problem. I plugged the fuel pump back in and it still cranks endlessly. It doesnt seem like the fuel pump is even turning on. I noticed after that i spaced putting on the foam sleeve, but i dont think that should make a difference.

any ideas?

First off never use a bigger fuse to solve a problem. They are there to protect the circuit and you could burn up a lot of wires. Sounds like you may have pinched a wire when you put the cover back on. Take it off and test the wires to make sure you have 12V to the plug still with the key on. Then check the ground as well.

I am not sure what the problem is. I would do some trouble shooting. First, Get a light tester and check to see if you are getting a good ground signal, and positive signal. If you are getting good signals, then check the pump to see if it is working. You may have a pump that is not working. Run a positive and a negitive from the battery to check and see if the pump turns on. Don't leave it on those lines for long. I am not sure how many volts the pump can take. Make sure that you check the fuel lines. Make sure you did not bend any lines when you were disconnecting or reconnecting the assembly. Also, use the right fuse.
Make sure you check to see if you are getting fuel at the rail.

You may want to check to see if your are getting a good cam and crank signal. Make sure your timing didn't jump for some strange reason.

I ope one of these helps you out.

Let me know how it goes

i figured it out. when i dropped in the tank,it pinched the power wire and grounded out. relocated the wire, and it works. now to find an FPR.

Good to hear that you got it working. As for the Fpr, try Aeromotive. They make great products.
