Well, I'm sitting here unable to go to work because I can't get my GLi to start. It usually starts instantly when cold, on the first crank (hot starts can require 2 or 3 attempts sometimes, if that's related). Today on the first crank it caught and fired for a millisecond or two, then died. After that, it will crank, but never sounds like it's combusting. I tried this for 5 or 10 mins then let it sit for 20 and still nothing, then again for another 30 and still nothing.
My wife had this happen to her a few weeks ago when trying to drive the car. We just took the other car and the Jetta started fine the next day. In a nutshell, I think it may be the differential pressure regulator. Has anyone seen one go bad? Does this sound like what happened then? I hope it's not it because they're supposed to be expensive, right? Any other possibilities? The car has a new distributor and plug wires, is set to 6 degrees, and has a new fuel xfer pump. Here's what the Bentley says in the troubleshooting CIS-E section and why I think the above: -Cold start or thermo-time switch faulty. Don't think it's this because the car doesn't fire and then run rough, it just doesn't start -Fuel Pump not running. I can hear the fuel pump whine when I turn the key to on. I checked the fuse is okay and pulled the fuel pump relay and put it back in. -Air Flow sensor plate rest position incorrect. Hmm. Maybe, but I'm not certain this could be it. -Poor ignition ground. I cleaned and put a new connector on my ground wire this summer, and it looks okay. -Coolant temperature sensor faulty or wire to sensor broken. Possibly. -Fuel Pressure incorrect. This is the one I'm betting on, as cranking it now sounds just like when you're out of gas or have the fuel pump fuse pulled. Bently says to Check differential pressure regulator, system pressure, and differential pressure. I'm not sure I can check the two pressures myself, but if I get some alligator clips for my multimeter, I can test the amperage of the diff press reg myself. Of course, this would happen while I've got the valve cover off my motorcycle, so I have to sit here and wait for my wife to come back from work and pick me up.
