Here is what I know:
1) No prior starting issues or fuel flow issues of any kind, car was running like a champ.
2) Starter was turning, starter was engaging, battery was fully charged, car would not start.
3) Listened for 2 second fuel pump operation when switching ignition switch to on position... no noise, so fuel pump was definitely not turning on.
4) After I got the car home (tow truck) I tested the voltage of the power supply wires where they connect above the fuel tank on the fuel tank access cap. With key turned to on I had 10 volts. I then hooked the battery straight up to the male ends of the same connectors (right on top of the fuel tank) and the fuel pump turned on, so I know the fuel pump works.
5) I went to checker to rent an OBDII reader. Plugged it in, device turned on, after I turned the key and tried to sync up the reader, it said "unable to establish a link with the vehicle". I know the OBDII reader works because I then tested it on my wife's Scion xB and it worked like a charm... What am I missing here?
I figure that if the fuel pump works, if I was getting juice through the wires all the way to the fuel pump, and my battery was charged at the time of the no start... there must be another reason why it is not turning on, like the computer is throwing an error code. That's why I got the reader. So I will pose two questions in an effort to save me from the clutches of the dealership. Please help with:
1) Why would the OBDII reader not be working? (Innova 3120 - Can OBD2)
2) Is there anything you guys can think of that would prevent my fuel pump from turning on? I know there are probably a million things, but give me all your guesses and troubleshooting ideas. I am far from good at troubleshooting, but I hate taking my car in
