motor turns no start

I can get the motor to turn on my 907 but it wont start. the voltage at the relay is 12.6 secondary out after pushing start button is 10.6 do you think I should change that, and could that be the only problem? I have foound a few other things wrong like the ignition relay not working swapped that out, noticed as stated that starter relay is 100 percent. Any help is good help. Thx

usually the most silly and often overlooked reason is that the kill switch is on OFF position.

Can your hear the working fuel pump?

My Pump stops working last Saturday...
All fuses OK

Yes can definately hear the fuel pump. Switch is in run position not off. I am at a loss, I have spark and everything, could it be the sensors not allowing the cpu to engage?

take out an injector out of the throtlle body an look for a spray while starting.
when you have spark as you stated and fuel (spray out of the injector) it should run.

I've cleaned injectors by connecting the injector to a bottle filled with injector cleaner and pressurerize to 6 bar air. than connect the injector to the battery with two leads. when you touch the battery with one lead the injector opens and the injectorcleaning fluid is pressed through the injector.
the procedure is very simple but effective.

Thank you, will try and get back to you.

fuel injector sending no fuel through have good power to connector and good flow through gas line. I guess thats the problem. Will have to order new and man are they not cheap.

Having 2 injectors fail simultaneously is pretty rare to impossible. Check the resistance of both; not sure what it should but but more than a couple of ohms and less than, say 50 ohms. Typically bad injectors go open circuit.

If you have good power to the connector do you have a good ground? Are you manually pulling these to ground, or running the motor to get them to fire?

The ground I am getting is through the pin connection not the chasis but both ground out fine. I assume I could get the injectors cleaned they have been sitting for quite some time. Just in case though does anyone know where to get the injectors besides having them ship from Italia.

16.1 ohms on both by the way

ok new delema, got the jets back from cleaning they work when i hook them up to the battery but not when everything is hooked through cpu, the 8 pin configuration is off some how i have a new voltage regulater that shows black being ground but on the schematic it shows black going to brown through the ignition relay but whenever that happens it blows the fuse in the relay instant. Any clues. Heck im just glad i finally saw fuel flow. But I need it to do what its supposed to. Could this be a direct short or maybe the cpu has an issue?
