Received and plugged in the Durametric and a fuel pump relay. Swapped relays and no change.
Durametric indicated the immobilizer is not engaged. The code I received indicated that there is inadequate fuel pressure at the injector rail. Because the car is an 2003 Boxster which is equipped with a non-return fuel system. Testing this system requires a Porsche System Tester and aren't covered in any manuals. The closed Porsche dealer about 125 miles away. I'm ordering a new fuel pump since it seems easy enough to replace. An earlier post in this string mentioned replacing the fuel pump but want to ensure the issue wasn't just a relay..

Once the car is running I will stop by the dealer and get a new RF for the key.remote..

I should also mention that when I turn the key to the on position there is a high pitch electronic tone coming from the engine compartment.

You can connect a mechanical gage,, you just need to add a test port if your car doesn't have one.
You normally insert the T in the feed line at the injection rail, you eill need the right fittings see a hydroaulic line supply shop..
its not always about the high tech solution..

But since you ordered the pump and its Easier to change than a tire.. I'd go for it..
You should be able to hear the pump with the frunk open and an ear to the tank bulge...

Spray some starter fluid into the throttle body and see if it fires up. If it does, you'll know with 100% certainty that the engine is not getting fuel and you can start going from there.

TheMitch

Yep, I did spray state fluid into the intake. The car fired up so it's getting spark, just not fuel.

If it just cranks after the car is hot and starts fine when it's cold, it's the crank position sensor.

TheMitch

Hot or cold, it turns over but wont start unless I spray starter fluid in the intake. Thanks for your suggestion.

Do the returnless systems have a fuel pressure regulator?

TheMitch

Great question. The return less system does indeed, has a pressure regulator as part of the assembly.

Byprodriver

Yes lot's of fuel pumps dieing these days, the fuel cools the pump so don't let the fuel level get much lower that 1/4

TheMitch

This 2003 Boxster spent the first 15 years of its life in
Palm Spring. I dont care how dry it is, 115 is hot.

This is a myth. The fuel running through the pump cools it too, they are designed to run without needing to be submerged in fuel. If they didn't they would be failing when the car is new. The car manufacturer would not allow this when the car is still under warranty. They are filing because they are 20 years old.

Yea if there is fuel pumping its submerged. The pump is located in the "canister" of the fuel pump assembly and the fuel regulator dumps the excess fuel into that canistor, thus keeping submerged.

TheMitch

Solved. Swapped out the fuel pump and it started right up. Kind of wished the tank wasnt full but as someone posted changing the fuel pump was easier than changing a tire.��. Thanks to everyone for your good support

See post 4, what do i get for being right . If u guys could just see me know patting myself on the back .
