Just a follow up on ranger 700efi, replaced ECU with a new one, carried it to a local Extreme Motor Sport shop and had it programmed. Runs great now but it won’t idle. RPMs at around 650, then dies. Any idea?

Good morning folks I have a 2009 ranger 700 XP that will not start. It’s not getting power 12 votes to the fuel pump or the coil. The code that shows up is 4341. installed a brand new ECU And still no power to the Coil or and fuel pump.. All of the fuses are good and all the relays are good when I tested the wire going to the fuel pump it shows 4 Amps. Ran a hot wire to the fuel pump and it works fine. The ECU I installed is part number 4011599. Also the speedometer goes to 70 mph when I switch it on and then drops to 40 mph and back-and-forth. I have checked the ignition switch and all the connections for the ECU and the Coil. Any help will be appreciated.
