Hello all. I have a 2006 Freestar SEL 4.2L. It died yesterday and won't turn over at all. Code reader says "No Link". When the key is in the on position the ?IMRC motor? runs constantly and so does another motor/pump mounted to the firewall between the cabin and engine compartment. This second motor has a hose running from it into the air intake plenum just behind the throttle body. I checked the fuses and relays related to PCM and starter and starter solenoid.

The second "motor/pump" is the vapor canister check valve.
Any ideas what it could be?

Thank you,
Brad

It was the 15AMP fuse under the hood that controls the PCM, injectors, and a few other things. I thought I had checked it but must have grabbed the wrong one the first time.

Glad you solved the problem , thanks for letting the forum know .

Well the saga continues...

Not long after replacing the fuse the engine started missing and throwing P0352 code. I pulled the ignition coil pack and there was a large crack. Replaced the coil and put new plugs in since I had it opened up. I checked the PCM connector and sure enough there was water in there. I thought I dried it out pretty well, but now after putting it all back together I have a P050B. If I'm reading the Ford troubleshooting chart correctly, this is either wiring harness or PCM. I'm heading back out to tear it all down again and check for water/water damage.

Cranked up the air compressor and started blowing. A ton more water came out of the PCM connector. I pulled the PCM and opened it up and sure enough there is a blown resistor on the board. I'm taking a trip tomorrow to the junkyard. I am going to attempt to pick up a PCM and put a new-to-me resistor on the board.
