JUST INSTALLED A NEW MAF SENSOR

Question:
I JUST INSTALLED A NEW MAF SENSOR ON MY 91 TOWN CAR AND NOW THE ENGINE WONT TURN ON EVEN THOUGH ALL THE LIGHTS AND ELECTRICAL THINGS FUNCTION LIKE REGULAR. WHAT DID I DO WRONG? IT'S A SIMPLE PROCESS????

Answer:

There is no connection between the MAF sensor wiring and the starter circuit wiring. The only possible things that could have happened here would be that either the battery cable connection is poor (if you removed one cable to do the sensor replacement) or you may have accidentally bumped a wire connected to the starter solenoid during the MAF sensor replacement. In particular, check to see if the small light gauge wire from the ignition switch circuit is connected securely to the starter solenoid S terminal. Also, (this may sound stupid, but it has happened to all of us at one time or another) make sure the vehicle is all the way in PARK position, or try starting it in neutral. Make sure that the battery voltage is 12 volts or higher; ford starters will not operate on lower voltage even though all other accessories will.
