cost of EDC injector pump service

I need to get one of my EDC pumps for a 300 serviced - its the last thing to be fixed in the entire system to stop the cold start non function bollocks - how much should I be looking at paying for a service ? I dont want to put a replacement in as most of the 2nd hand ones have the same problem already !

pass i bet you will be in the hundreds soon as you mention fuel injector pump they clap your hands

go to a tractor repair company and see what they say they may know of a compny closer to home that repair them
