Check for fuel at rail 87 944
What's the best way to explain how I can check the fuel at the rail and the injectors on my 87 944 base. I am tracking down a stall/no start and have exhausted the electrical side, now I need help identifying the fuel rail, injectors and fuel pump location. Thank u all.

Remove the nut at the end of the fuel rail. Be careful there is a small bearing inside that acts as a stop. Hook up a hose and place in a container to catch fuel. This will at least let you know if you’re getting fuel to the rail when you turn the fuel pump on. You can add a pressure gauge to see if you have high or low fuel pressure.

Have you triple-checked the connector for the reference sensor at the back of the engine? I chased stall/no-start issues for weeks, replaced a bunch of stuff, checked fuel, etc. The connector seemed fine and tight, but was only making occasional contact (and the nearby wires can crack). So check that stuff first, even if you've already checked it!

The fuel pump is located in the pass side rear. Under a small cover located in front of the fuel tank
