My 04 R50 won't start, not sure what to do

I was hoping somebody could point me in the right direction.

With the help of the Pelicanparts site I replaced the camshart sensor o ring. All went well, although I was not able to disconnect the sensor so I removed the radiator to gain access. I replaced the o ring, put it all back together but now my car won't start.

About a month ago I replaced the spark plugs and wiring and the engine has run well since. So I don't think it's the plugs.

I've done the following:
- recharged the battery
- when turning the key I can hear the fuel pump
- when starting the engine turns but it won't fire up
- I even disconnected the battery for about 7 minutes
- I checked, no codes

What am I missing? Any suggestions.

Trying to recall what plugs might have to be disconnected when you remove the radiator but only can visual the one at the top near the air inlet on the radiator. Or, when you attempted to disconnect the sensor, a wire in the harness broke.

Yeah, I'll open it up again and check the radiator connections. Let me see what I find and reply. Thanks for your feedback.

I have disconnected the radiator and crankshaft sensor and plugged them in again. A couple times the engine started but stalled within a couple of seconds. Now I'm suspecting that the crankshaft position sensor is acting up.
