A week or so ago, I mentioned that I’d picked up a 912E project car. Well, this weekend I had some time to really dig into it and see what was wrong. I knew that it would crank, but wouldn’t fire, so the issue is either fuel or spark. The easiest thing to do is check spark plugs, so I pulled them out and cranked, and they all fired. Cool. Next up is fuel. Turn the ignition on, and there’s no sound of a pump priming.
Okay, so it’s the fuel pump. I drained the tank and checked inside for debris, looks clean as a whistle. Removed the pump and bench tested it, it kicks right on and flows just fine. Pump back in, fuel back in, jump the fuel pump on with a spare battery and kick on the car. It stumbles at first, but settles into a nice idle. Betcha dollars to donuts it’s a DME relay.
So yeah, I have a Porsche and it makes Porsche noises (well, Volkswagen noises). As a friend recently said, “Nearly impossible to kill a stock Type IV. Also, to enjoy it.” Truer words have never been spoken.
