This is my 1995 940 Wagon, 8-Valve with 230k miles driven primarily by my wife.
On her drive home from work today on city street, the car suddenly died. I had to come give her bumper a gentle push with my c70 just to get her up the incline and out of traffic. I cracked up my front license plate cover, but it was fine beside that.
She said the car didn't sputter, but just suddenly died while she was driving up the incline. Her tank is half full and the car was warm (normal) when it died.
It was too loud, too dark, and too damn cold to do much more than confirm that the car was cranking normally and call a tow truck.
Got the car home and under the car port. Still too damn cold to do much, but I was able to confirm that the fuel pump is cycling, and it is running when 12-volt power is applied directly to the harness. Relays are clicking and I can hear the low hum you'd expect from the pump when I turn the key.
The tach doesn't move when I crank, but I'm not sure that's meaningful on this model. I had a 740 with a snapped timing belt and this doesn't sound like the dry crank you get with a busted timing belt.
Considering how freakin' cold it is, I want to do as little testing as possible so I'm looking for likely candidates.
Fuel:
After cranking, I'm going to pull the #1 spark and check the plug for wetness. If dry, I'm planning to loosen the fuel line at the rail, put it into a container and crank for a short while. If I get nothing, I'm gonna be pulling the sender unit (again) to see if the hose popped off the pump.
Spark:
eh.. no quite sure. I've got an inductive timing light that could confirm ignition pulse, but beyond that I dunno.
Other Issues...
The car threw a CEL O2 Sensor Code back in the Spring. After re-setting it, I installed a new OEM Bosch Sensor, but the code came back and keeps coming back. Fuel economy has been sub-par for a while.
I had to install a new starter in late Summer.
In the Fall, the car had several no-start episodes that I eventually traced back to recurring corrosion on the + battery terminal.
Any thoughts?
