Hey whats up guys. I recently landed hard on the left side of my 929, pulverizing the stator cover and that side of the crankcase. It sat for about a month and then after swapping the motor I attempted to start it, but the fuel pump is not priming. It cranks strong but no start, will make a few puffs of smoke on ether. Ive checked the fuses and fuel pump but they're all good. Can anyone steer me in the right direction? I wanna ride!!!

You swapped in a new engine that you haven't yet managed to run at all?
Have you confirmed you have spark?
Is the bank angle sensor mounted correctly and connected?
Is it flashing any error codes?
Without the fuel pump it won't fire as it needs pressure to operate the injectors. Try running power directly to the pump and see if it fires then.

Its not flashing any error codes but it does have spark. I tried running power to the fuel pump but the engine will only sputter and stop almost immediately after i stop pressing the ignition button. the bank angle sensor was mounted correctly i think but i haven't checked to make sure its definitely connected properly. thanks

make sure its not stuck..sometimes after a fall they get hung up...check your side stand switch too..you never know..iam guessing youve got some kind of spark for it to sputter and puff some..but is it strong?

That sounds troublesome. If you have spark and you can't get it to run on starting fluid, then run a compression check.

I asked before, have you run this engine at all?
Have you checked the compression and/or valve clearances?

No i havent run the engine at all nor checked compression or valve clearances, i took the word of the guy i got it from that it would be in proper functioning order.

Then it's probably worth doing a compression test to confirm that it is good. Was any reason given for why the engine was removed from the bike originally or how long it was sitting?
When you said if "puffed" I'm assuming you mean it didn't actually fire?

I got the engine off ebay from a very reputable seller and it was from a light collision bike but the engine was in immaculate condition. I dont know how long it was sitting, but certainly several months at the least. No it wouldnt actually fire even with the fuel pump getting direct power, just generated a few puffs of exhaust as i pressed the ignition button and not the normal roar im used to.

You need to confirm you have spark then.
