They do fail, Them ECU’s Options

[Porschef]

A couple weeks back I hit some real rough road on my way home from my mechanic neighbor’s shop. The car started running out of power, I made it another couple hundred feet before it died. With help from said neighbor we were able to push it down the road to a safe spot, where Hagerty towing picked it up.

I have a fuel pressure gauge in the engine bay, whenever I would engage the pump it would build up pressure and immediately fall to zero. I thought I had a bad injector or maybe the cold start valve failed, so I pulled them all individually and checked them; they were all leaking. A Noid light showed them all to be open. WTH? My neighbor suspected the ECU, but based on what I’ve read they rarely fail.

Anyway everything else seemed ok so I put out a WTB and Jim Hoyland responded with a unit and an offer to check it out and then buy it if it worked . So last evening I pulled the harness off the one in the car and plugged it into the new one. Presto! Pressure held right where it should. A quick experiment putting the harness back into the old one got the same previous result. So I’m pretty confident that the problem has been resolved.

As much as I wanted to start it, I did not based on the oil reeking of gas. So I’ll do a change, and see what happens.

Big thanks to Jim for helping out, it’s a great community. (IMG:style_emoticons/default/beerchug.gif)
