Question about 2001 Ford Explorer Sport Trac
I crank it will try to start but then cuuts off. I got a new battery changed alternator but still nothing. Any suggestions. And battery still shows it has no charge.
check what the diagnosis machine will give if there is no data then check if the starter crank sensor is getting any power

Most important when you replace the battery or alternator is to check the charging current to the battery. If not the RECTIFIER/REGULATOR IS FAULTY. You must check the alternator voltage to the rectifier/regulator and then the output which is the charging current in parallel to the battery.
There is a reverse voltage diode to prevent reverse flow to the alternator therby draining the battery.
So check this circuit and I hope this could be the fault.
Please check and comment , if helpful vote me.
