Have you tried the self diagnosis tool to test the electrical? Have you installed a tank and injector from another 4rt that you know works right? Were the fuel filters cleaned when the pump was cleaned?

If you are still having the starting problem, try cleaning the fuel filters. There two filters, one at the bottom of the pump, looks like a tea bag, can be removed from the pump by carefully prying off the clip that holds it on. The other filter is round and part of the fuel line that comes out of the top of the pump. Blow compressed air in the opposite direction of the fuel flow to clean it. Cleaning the filters solved my starting problem for 2 1/2 yrs, then the pump failed, and I needed a new one.

I recently had to replace the fuel pump on my 4rt. The cost to purchase a new pump was prohibitive in North America. BVM Moto in the UK was far more affordable, with the pump costing only $397 Canadian. This includes shipping, which took only a week using the postal service. BVM Moto's service was excellent. Worked out all the details via email. They were very prompt responding to my queries. Sure won't hesitate to contact them again for parts. Although I ordered numerous spare parts with the pump so hopefully won't need more parts soon.
