Hello everyone, I have the above van with the following fault. When you drive the van and go over 3,500 rpm the EDC light comes on, the van cuts out and you have to cycle the key to start it again. The trouble code stored is 1187 Rail pressure monitoring devitation. I assume this relates to a fuel pressure problem but could do with some advice as to how to check the system to see where the fault lies. I remember a post about regulator problems but when I checked I could only find a post that related to it not the actual post. Thanks for any help or advice. Ronan
