*That* makes a lot of sense, SkiMachine! Unfortunately, the location of the FPR makes it a difficult diagnosis, let alone changing it out if it is bad. I figure it's worth $1000 if it's aircared (bad front main seal, also leaking oil out of the pan) $400 if it isn't. I don't have the luxury of time (any more!) or space (thanks, Township!) so I think I'll let it go. I do appreciate your help! Greg

Trying that right now, Kingman. The only code I pull is 34 - knock sensor. This morning, I went to start it, and it fired right up. :weird: sounded, felt like it was running smoothly, so I thought I'd take my chances on passing emissions... Failed on all three criteria - NOx, CO, & HC on the driving test... I can't imagine the KS causing all this. Getting ready to throw in the towel, but I do appreciate all help & suggestions! Greg

Thanks for the response, SkiMachine. The thing is, I can get it to start with the connector hanging, so the basics are good. At the assumed 20C, I get enough air, fuel, spark all timed together for it to run, albeit roughly. I think I can rule out bad gas on this basis as well. To summarize: Connector hooked up to temp sensor = crank, no start Connector hanging = start, rich running condition I'm going to start fresh this morning and trace the wires on the connector - they seemed pretty brittle, and could be cracked, and maybe there are bare wires rubbing, but that would likely be the case if the connector was hooked up or not, right? One more tidbit - after it starts with the connector disconnected, I can reconnect it, and it will start ok, but it runs like it does while disconnected. Just bought another vehicle last weekend - all I want to do is get this thing running well enough that I can put it up on Craigslist and sell it! Thanks for the help! Greg

Hi gang - I've been a member for almost a year now. Bought a 93 for my daughter to learn to drive on last November. It's been a 4th vehicle for us, sitting for most of the past year. This summer, in trying to figure out an issue that had it running too rich, I replaced the coolant temperature sensor. (VW guy here - that's one of the first steps in that world...) Anyhow, the vehicle sat for a couple of months after my wife took it on a girls road trip, where it ran well for them. Last weekend, I started it up and changed parking spots. A couple of days ago, I went to start it up, and no go. Lots of cranking, no catching. Here's where it gets weird: when I unhook the coolant temp sensor that I replaced, it starts and runs like a dog. Really really rich, but it starts. So I figure that I had a bad sensor. I bought a new sensor today, and same deal. I didn't install it, but hooked it up hanging loose, and it cranks like crazy, but no start. Unplug the new sensor, and it chugs to a start and again, runs like a dog. I've gone over the service manual, but can't figure out the EFI system. There doesn't seem to be anything in the troubleshooting part of the manual that would cover this. Can anyone out there give me a place to start looking? Cheers, Greg
