Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
no spark... just died heading to work....is there and where would the rely be located for the pcm??...the only code pulled was for the coil pack, there are 4 on each ... would it be normal for both to go bad at same time??

The 5.0L V8 in the 2001 Explorer has two coils - each one firing four plugs.

The ignition system / spark is controlled by the PCM.

There is a PCM relay in the battery junction box - the box with fuses and relays near the battery.

The crankshaft sensor is also one to have a look at to make sure it is sending the signal.
thx dave, i will check for the relay first , the crankshaft sensor tested fine with ohm meter, i pulled the pcm and took to the local ford dealer to have tested....which they said it would have to b on the vehicle to test....again thx for ur input it will help me to better diagnose....any other info would be helpful....
