Has anyone had a fuel shut off solenoid get stuck?
Full story:I have an AHU swapped in a Eurovan. It's been there for 50k miles. It was getting tired so I pulled it for a rebuild (50k in the Eurovan, unknown total miles). I thought I would put a spare AFN in while I rebuild the AHU so that we could still use it. The AFN has been sitting in my shop for a couple years.
l have the AFN fully installed and it should be ready to go BUTTTTT I can't get any fuel. I cracked a line at an injector and turned it over and over. No fuel. I've checked the solenoid, it is getting battery voltage during cranking. It "clicks" and sounds just like my B4 that does start. I pulled the engine side harness and checked it with an ohm meter for a broken wire. It all looks good. I can pull inlet hose off the pump, pull a small vacuum and get fuel in my vacuum pump reservoir. I scanned it with VCDS and I get a coolant sensor open error... but that's it. What else could it be besides a stuck valve if they don't stick?
