Porsche 911 3.2 New Shift Knob

 Some pictures of a new knob I bought from Moore Knobs.

Speed Sensor Replacement

My 911 could not start. Both alternator and fluid pump were working fine. Using the diagnostic method below I found out the resistances were zero. 911 3.2 engine requires both Speed and Reference sensors to work to start the engine.

Speed and Reference sensor connector locations and diagnostic method.

Sensor with harness part numbers. Other part numbers -91160621501

91160621500 - this is an old number
ref. 026121002 and cross reference 12141708619 m14

Sensor positions and gaps between the sensors and the crankshaft.

Porsche 911 3.2 - Transmission Fluid Change Out

This is to show some experience I went through during the fluid change out. 

First transmission drain and fill plugs part number. They both are the same plug. 

Drain plug captured some metal shavings. Not a good sign. The plug on the left is new. 

Porsche 911 3.2 Oil Change

Engine Oil - Valvoline VR1 20W-50 High Zinc.

A few good oil change videos.

Porsche 911 Fuel Pump Relay Survival Kit

This is to show how I make a jumper to bypass the Fuel Pump Relay. This isn't a permanent solution but it can start up the car.

Connect the wire between pins 30 and 87 to turn on the DME and between Pins 30 and 87b to turn on the fuel pump.

• Pin 85  [1] - Ground to the DME/injector relay coil
• Pin 30  [2] - +12V directly from the battery
• Pin 86  [3] - Switched +12V from ignition switch (bus 15)
• Pin 87b [4] - +12V to the fuel pump, switched by the fuel pump relay 
• Pin 87  [8] - +12V to the DME and fuel injectors, switched by the DME/injector relay
• Pin 85b [9] - 0V switched to the coil of the fuel pump relay from the DME, pin 20

 Diagram shown is looking into the connector in the CAR.

  

This is shown the 87 and 87b are connected to the wire. As soon as pin 30 is connected with the other 2 pins, the fuel pump should start to run even without the ignition key in the car.

To make the jumper, put 2 wires with RC plugs to make a 3 connections together.
