I have been assigned the task of wiring up a 03 GSXR 600 motor in an almost FSAE legal vehicle and cannot get it to start.
I believe I have correctly bypassed or implemented all the ridiculous amount of required sensors (Tip Over (22 K Ohm), Ignition (100Ohm), side stand, neutral, Gear Position) and even have gone as far to give it fuel pump on and starter on signals. All the sensors are getting the 5 volts, fuel pump primes, and I get spark on all 4 cylinders but only cylinder #1 is getting fuel. I have tried a known to be good ECU and it has the same results. I am curious if anyone had an idea on what would cause this? My first hunch is that either the cam or crank sensor is not working correctly, but the crank sensors resistance is in spec and since #1 is the only one working I think that the cam sensor is fine.
Was wondering if anyone had any ideas or could defiantly say it is the crank sensor, I don’t want to lug an oscilloscope all the way over there if there is a simple solution.
