rxp no spark/ injectors not spitting!
06 rxp turns over fine has new battery i thought maybe voltage wasnt right so i changed it. I have swapped back and forth between stock ecu and rr ecu. i have put stock injectors back and the brand new set of 48's neither spit fuel so i am not getting current apparently to these areas. i know i should probably test the stator but i thought maybe i should ask if anyone else has ever had similar NO spark and injectors not spitting maybe someone could save me a ton of headaches. i appreciate any help!! thank you!!

Check your fuses, crank sensor, cam sensor, grounds

All fuses are good, the grounds are good I took them off sanded the block a bit to make sure I'm getting good contact. As far as checking the cam and crank sensor any help would be appreciated unless its in the manual in that case I could just check that out

cleaned up both sensors and still nothing engine turns but no fuel spits out and the fuel pump is good i hear it running, its a brand new walbro.
any help would be appreciated im sure someone has had to run into something similar

Did you ever put the A, and B connectors on backwards at the ECU? Could have damaged an ECU. Where are you looking for fuel to spit from?

As MSRXP, I believe its the cam sensor.
Did you test it?
Here is an extract from a manual:-
Disconnect the CPS connector from the wiring harness and check the resistance of the sensor
itself. The resistance should be between 190 Ohms and 290Ohms .
Otherwise, replace the CPS.
If resistance tests good, reconnect the CPS and disconnect the ECM connector A on the ECM.
Using a multimeter, recheck resistance value between terminals 5 and 19.
If resistance value is correct, try a new ECM. Refer to ECM AND MPEM in this section.
If resistance value is incorrect, repair the connectors or replace the wiring harness between ECM
connector and the CPS..."

i never put the connectors backwards but regardless i tried a rotax reacing ecu also and no difference. im looking for fuel to spit out of the injectors with the fuel rail out.
I will test the cam sensor as per the manual thanks for the feedback

Get a noid light tester for the injectors and see if flashing (getting voltage) and how are you for sure not getting any spark.
What injectors are they and how long have they been sitting, if you get a noid light and you are getting voltage tap on the injectors and see if they may be stuck from sitting..
