2004 Boxster S - Doesn’t Start!!
 

Hi Everyone

So today my 3.2l, 2004 Boxster S failed to start!
Drove around 40 miles in it no issues. Stopped and a friend house and then the car wouldn’t start. Started chugging for a little bit and cut out.
Called out the AA and they said that it May be the fuel pump and found no amps going to the fuse
so what would people suggest?
Relay? Fuel pump? Please help!

Crank shaft position sensor?

Is she throwing any codes?

Check all of your fuses first and foremost. Redundant, yes, but best to clear the easiest options first.

If the fuel pump is found to be fault, DO NOT replace it without replacing the sending unit as well - Porsche idiotically integrated the fuel filter into it in 2002. :rolleyes: I had this issue several years ago where I went through 2 brand new OE fuel pumps then discovered my filter was clogged. This, of course, was after having a no-start issue where it would crank (tach moved), but had no fuel at the rail. In that scenario I had also replaced the fuel pump relay.

My problem turned out to be a weak "positive" ground in the engine compartment. It was rusty, and if I wiggled the cable and turned the key the engine would start. Disconnect the battery. It is located in a black plastic box next to the power steering reservoir. Use a screw driver to pop the box open and a 14 mm socket to remove and clean the nut.

Thanks for sharing the conclusion. :) I had that cable off recently when replacing the voltage regulator.

Not the OP
 

I am not the "original poster" ...just sharing what my problem turned out to be ...

Fuel pump relay? You can google search to see how to jumper it for testing or pop in a new one and keep the old one for a spare if its still good.

It would help if I had read who posted it. Whoops. https://www.vwvortex.com/Anthony/Smilies/redface.gif I’ll just blame it on being on my phone.

Did this turn out to be a crank angle sensor problem?

This was the fuel pump on this occasion - £200 for new part.

The car wont start again now, last time it tried to crank but this time not at all now

For anyone else having fuel pump problems, here is a video I did on how to test the fuel pump.

So fist time it would not start (but would crank) was fuel pump issue

second time 6 months later would not start was water in the immobiliser
