I don't have my Turbo anymore to check if there are any small hoses around the throttle body that can be easily disconnected,but I would say the easiest would be to take the clamp off one of the hoses that connects to the Y pipe. Just take the clamp off and pull the hose off the Y pipe enough to insert the tip of a straw attached to a bottle of starting fluid. Spray a bit and then try to start it. If it starts,you are 100% missing fuel,which I suspect at this point...

Connect the 2 wires that go to the switch, thus eliminating it.

Checking the clutch safety switch is a waste of time IMO. If the switch is bad the car won't even attempt to crank because there won't be any power sent to the starter. All you'll hear when trying to crank is " click click " or absolutely nothing.

Can you hear the fuel pump run pressurize and stop, with it in start mode before cranking?

Hi guys, thanks for all the feedback!

Problem was some short cut with the wiring of the fuel pump....being solved right now!

Thanks

Kevin

Pc007, You need to replace your fuel pump. You can measure the amperage draw. But the temperature of the harness connector, shows me that you have an issue. The wiring is the result of the high amperage draw from a seized pump or shorted internal wire.

nothing like internet diagnoses re the fuel pump.. lol. what were the chances...

Thanks Kevin

The guys told me that there's a short wire but will test the pump to make sure it's ok, if not...new pump!

I have seen this symptom in many older cars. The fuel pump gets older and draws more current. Eventually, it draws so much current that it starts to melt the power wire. I have a SAAB fuel pump canister where the fuel pump connector and holder have a big hole melted through them, as well as the wire insulation on the power wire. While it is possible that it may be a wire short, it is more likely the pump is drawing too much current due to its age or some obstruction due to a split fuel hose in the tank allowing debris to enter directly into the pump inlet.

BTW, this also happens on old auto HVAC blower motors and radiator cooling fans.

There has been two updated fuel pump from Porsche..

The short can be from the top tank connection, or the harness between the top panel and pump.

If you have not replaced your pump OR if your pump has not been replaced since new.. Replace the pump assy. Again, if you have owner your car for at least 3 years. And have no service records of a pump replacement>>I am recommending that you replace the pump assy. I would also inspect the venture lift pumps and wire support that are inside the fuel cell.

This type of short doesn't happen out of the blue and by itself.
