98 boxter fuel pump issues
I'm trying to help my father in law fix his boxter. I was driving it one day and it just quit out of nowhere coming up to a red light. Its a stock 2.5 with tiptronic. It would turn over til the cows came home but wouldn't fire. He owns a shop, so his techs have looked at it, even put a new fuel pump relay into it. The pump works if you manually put power to it, but doesn't run normally like it should. I spoke with the tech thats been working on it and he said theres 3 wire to the relay, and they all seem grounded, none are getting power.
Is this a problem with the crank sensor, cam sensor, or possibly the anti-theft? It seems weird that it would die out of nowhere during normal driving.

Check out the crank sensor; when it dies, it turns off the fuel pump...........

listen to JFP, and let me share an advice he gave me a year ago.
get yourself the Duranetric diagnostic tool. if you are working on the car, and your father in law intend to keep it, it will pay for it self in the long run, and will save you a lot of time as well.
if the crank sensor is in fault, the Durametric will find it. don't start throwing parts into the car for no reason.

Thanks for the help, I'll run the durametric idea past him. He owns a body shop so he may get some use out of it but he rarely gets porsches in there. I think he's ready to give up on the car since he inherited it and he's already got a bit of money into it from the body work it needed. I'll see if they checked the sensor today, hopefully that works since I love this car and will probably get more use out of it than him!

How will Durametric find an intermittent faulty crank sensor?

If the car won't start, why do you think it's intermittent?

I'm guessing you don't have an answer to my original question then?

Its not intermittent, the car wont start at all. I checked in today and evidently noone there knows how to work on a porsche. I'm no mechanic either but I'm sure I could figure it out without a problem with less than 5 mins searching online.
