Question about 2009 Ford Ranger Regular
I have replaced the water temperature sensor but still no joy. The battery and alternator work fine too. Could it be a cracnkshaft sensor? fuel pump relay? or a sticking solenoid when it gets turned off when hot? please help!

Like Laurie Mack said. It is the inertia switch below the glove box. Here is some funny information. DON'T change the fuel pump first. Interesting fact: I bought the new inertia switch from Ford and the install instructions that came with it said to install the switch in the protected area to the right where the fuses are. It is like Ford knows it was a dumb place to put the inertia switch, but they won't let you know until after you buy a new one. I have read at least 20 other people on here that had the same problem I just had.

You should have to get the truck scanned for codes, so there will be an exact direction to diagnose.
It could be you gonna have a bad valve cover gasket or the electrical connection that goes from valve cover gasket to injector.
It's also possible that the injector could be bad but you would have to test the electrical system to injector to determine that. I recommend you have truck scanned and we'll see what code it is and try to figure out what's going on.

Just for the hell of it replace the fuse with a new one relative to the fuel pump also clean and inspect all electrical plugs and connections associated with the fuel system. There may be a bad ground with out the truck in front of me it will be difficult to go any further it is possible the pump is not creating enough pressure to close the relay have you replaced the fuel filter? If possible do a fuel pressure check at the fuel rail it should be 30 - 40 psi if not replace the pump.

Did it run fine prior to replacing the alt and battery? Check over where you have been working,sometimes things get bumped/disconnected. Fuel pump shut-off switch is in one of the kick panels near the inside of the doors. Reach up over the top of the kick panel. The pump relay are near the battery. What happens on this model too,is the heater leaks on the computer,which is under the heater core.The coolant/water shorts it out.
