Default Check Engine light is on and VCM doesn't give any info

I almost thought it wasn't going to get home the way it almost stalled at the red light. Any ideas???

Disregard if you already know this. VCM with a check engine light won't read anything while the car is running. The key needs to be in position 2 to get the code.

It says Fuel 14/Fail 14. Is that a fuse or is it that the fuel pump needs to be replaced?

Does anyone read the sticky section for the S91_AJ6 Engine Management Guide I uploaded???????

That document will tell you more than you need to know about the engine management.

FF14 COOLANT TEMP SENSOR AND CIRCUIT.

Is it safe to at least drive it to the service place? It's about 15 miles away.
