Yes, I have another temp sensor just in case. I replaced the whole linkage assembly last spring on the cable side of the throttle body with a new actuator and small bearing that the actuator rides on. I should try the other temp sensor first before diving into the bleed screws. Have not thrown a "14" trouble code but sometimes those don't show up. Aren't Magnetti-Marrelli FI systems fun? Yes, when I got the replacement linkage parts, both idle set screws were supplied with Loctite on both and they were quite tight after being adjusted.

Yeah, the pump should be smooth. Has a strainer and a filter in the tank too

When I get back home from Florida, I will change out the pump, filter, regulator and screen from Quantum. For less than $100 it may be a good move.

Do that pump first for sure. I hear mine initially when it pumps up then after a few seconds it's all quiet.

I have an ‘01 FLHRCI, I bought it in December… the fuel pump sounds very smooth when powered up, but makes a grinding type sound when powered down! This is my first EFI bike… is the grrrrr sound typical ?

You would figure that once everything is at proper pressure, if the ignition is turned off that it would come back on and the pump would be primed sufficiently. Not the case for me, Everytime the ignition is turned on, I get the same clicking sound from the pump! I think an order from Quantum may be in order!

Mine makes the grinding/clicking noise when the ignition is turned on (priming) No noise upon shut down.

If you need to replace, here is a link to Quantum for the pump you would need.

I'm not sure what mine is. I want to say Quantum but I'm not positive. I got it brand new on ebay. It was noisy when it was new but it barely makes a sound now. Changed it out along with the filter when I blew mine up. ALso pulled a ton of rubbery **** out of the crossover tube. Must have been from the factory when they sealed the tank.
