The car quit running will driving on road, approximately twenty five miles per hour. I had just put fuel at gas station. I checked for fuel pump operation, I can hear the electric pump come on and I add fuel to intake and still will not start. I noticed that spark is intermittent at spark plugs. It detonates and immediately shuts off and will not idle.
what should I check?

If the check engine light has come on, check to see what trouble codes are stored in the computer. That will be a starting point for us. Let me know what you find. (Note: Intermittent spark may be the result of a bad crank sensor or wiring issue to the sensor)

No link could mean a blown fuse, scan tool not compatible or a fault with the Engine Control Module.
I would suggest checking the fuses and if you have a test light, use it to check pin # 16 of OBD-II for battery voltage.

The OBD port is under the dash on the driver's side of the vehicle. It's not the actual computer, but rather the port were you attach the scanner.

Ok, I saw two pins on the OBD11 connector, with key on, the pin connector on the right, looking straight at connector, has a dim light, not bright like the brightness on a fuse. Let me know, thanka.

The connector has 2 rows of 8 pins with some pins empty. It should be the last one on the right. What did you use to get the light?

I am not sure if you are showing the correct pin. What you mentioned could be Pin # 1 or Pin # 16 as they are diagonally opposite. The color of the wire should be Blue/Red (blue with a red stripe) and it gets its power from Room fuse (15 A). Is the room light light working?
