Went to turn her over this morning, and nothing. It would crank, but not catch.
Backstory: Changed the oil and filter about a week ago. Almost immediately after, coolant sensor says that fluid is low. Ok, so I topped the overflow bag up. Light goes away, and all is good. Well, except that now it sounds like there is fluid rushing just behind the dash. I assumed that I got some bubbles in the line when I topped up the bag, and I'd just need to outgas it when I had the chance. (wouldn't think this was relevant except for reason #3 I describe below)
Last night, we took the car for a short trip, and it seemed to hesitate a bit for the minute or so after she started, but that cleared up pretty quickly.
Jump ahead to this morning, and nothing.
Used an inline spark checker, and the spark seemed kind of slow, weak and yellow, though not having used this tester on the passat before, I dont have a good baseline.
I am getting fuel at least to the engine compartment as I pulled the line from the fuel rail and cranked it. Got a couple spoonfuls of of fuel in about 3 seconds.
I;ve been reading the forums all day, and it seems like folks have said either 1. coilpacks, 2. ICM or 3. coolant temp sensor.
I tried to pull OBD codes with my little actron, but it says no codes available, and I never threw a light either.
Anyone have any ideas?
