Fuel pump not getting power
Hey guys,
Well just some background. Full ninja 300 swap for my old 1990 pregen. It came with full harness and ecu, etc. Only problem I had to deal with is the fuel pump and regulator, which I solved it with one of ecotrons pumps and regulators. I finally got everything together and ready to start and all it does is cranks. I did hear some noise at key on but it wasnt the pump. It was the sub throttle adjusting itself. Which sounds a bit odd..... It moves a bit and settles back. But I took a multimeter to test to see if I was getting any power to the fuel pump at key on but nothing. The bike is showing a check engine light but since it has to deal with the fuel injection system it doesnt throw a code for me to check. Only thing I can think of is a faulty Tilt sensor, or because I am missing the kick stand sensor. Any ideas? If I unplug the Tilt sensor will it not start if thats missing? Also is the sub throttle moving and making noise normal?

I have no idea, but I guess that the tilt sensor should unable the sparks.
Did you check those? I also believe that the tilt sensor is a normally open switch, but again, I am not familiar with the 300.

For the newgen bikes is the kick stand need to be plugged in? I took my kickstand off but i have the switch if i need to attach that back on. Thought if it was off it wouldnt need to be plugged in

From looking over the service manual, seems like if the down sensor is bad or thinks its on its side it wont run the fuel pump or anything. Just crank and flash the check engine like. Just like what it is doing. So my question now is do I have to buy a new down sensor or anyways I can trick the ecu to run like it was there. Otherwise ill probably have to buy a new sensor since I know I dropped it once and I knew it would bite me in the butt......

Did you jump 12v to the pump to be sure it runs?

yea i did that. The pump runs. I confirmed last night that injector 2 and fuel pump no power at all with key on. Supposed to have power for 3 seconds.
I need to take the tank off and find the down sensor and see if thats the one at fault

Well an update. I got a friends vehicle down sensor and swapped them and still didnt fix the problem.
Looked at a few forums about issues with other kawi's with this issue and came to one that might fit. There were only two things that I rewired to work for the motor swap. The pump and the ignition switch. My switch is from 1990 and I dont think it has that resistor the newer bikes have/need to run. I read that the kawi bikes need 6 volts to come from the grey wire for the bike to run. Can anyone confirm this? I checked the bike today and was getting a full 12V coming from the battery and going to the ignition, which I read is wrong. If anyone can please chime in that would be great. If not ill go get a 100 ohm resistor 1/2W from radioshack and solder it in the wire.

Well as an update:
All Kawasaki models that have digital fuel injection need 6-9 volts coming from the ignition switch (grey wire) so I sorted that out with two 100 ohm 1/2 watt resistors. I got the pump to turn on and run, spark was present but could not gauge how much since my battery went dead. I found out because the gauge was turning on and off on my while i was cranking the engine. But no check engine flashing. So hoping after a fully charged battery it will run.

Last update. Got everything running with the battery charged. Its running but havent tested it on the streets bc of the weather but looks sound to run strong. Only thing that isnt oem on the bike is the fuel pump i got from ecotrons and seems to be working very well. Happy with the swap and how easy it was.

Any more updates on this or more details on the swap? I would be curious how everything fits under the stock bodywork and/or mounting issues you encountered

I did a swap with 300 engine and got the wiring harness with it plus ecu, and the stock header. Everything was just modified to fit around everything but only thing that really needed modifying was the front mounts needed to be 1/4 inch wider on each side (kept pregen radiator). And shorted the end of the header since the pregen is a bit slimmer than the 300. It fits under stock bodywork, only a bit bigger than the pregen motor. Works fine, put over 3k miles on it since the swap. And the pump from Ecotrons worked fantastic.

I have a few more questions.
Would you do it again? Did it gain any weight? Was it a night and day difference to ride? Did you happen to gather any performance data?

I would like some...
did you use the 300 TBs ? what final gearing are you using ? does the chassis feel a bit less stiff ? any feel of difference of the center of gravity or balance on straight or out of corners ? can you give us any other feedback ?
