buy from FORD or International, parts store CPS's are not usually worth the box they come in. The Grey CPS works fine in my truck, others have issues but it is a truck by truck basis but I have never heard of a truck not running at all with a ford CPS. Usually the problems are more performance related. If you still have the Black factory CPS your truck should be covered under the recall. If you are broke down take the old CPS and your VIN number in to a dealer and they may just give you a grey CPS. On the other hand you may just want to buy one in case the CPS isn't the problem so you can keep the black one. they are relatively cheap...$20 I think from a dealership.
