Need help with a 2002 virage 800i

[Jonyota]

Any help would be greatly appreciated. I bought the ski knowing it needed the emm repaired. I have had the emm fixed The problem is the ski starts and immediately stalls. I installed Kawasaki inline fuel pressure regulator. New tps. I have proper voltage to injectors. Fuel pressure is around 25 psi. Compression is 150 psi on both cylinders. I can get it to run with fuel down the throttle bodies. I do not know if the injectors have been swapped out. Any thoughts or suggestions would be great. Thanks

So its pretty clear you probably have spark and are not getting fuel. First place I would look is the stator output if the emm is known yo be good. Check the voltage at the injectors and see what you get. Should be around 20 volts cranking and around 45 volts running.

Welcome

Does it stay running if you first disconnect the TPS and then start it?

If still not stay running, put a multimeter red probe on the White/Red injector power wires (black probe to engine ground).

Do not unplug an injector, find some other place to tap into the White/Red wires. Voltage should jump up to around 45 volts as soon as the engine starts and remain fairly stable.

[Jonyota]

Voltage is 45 at injectors when it starts.

Not sure if this is an issue or not but the ski cranks without the lanyard installed.

[Mr. Matrix]

That very well could be the issue. I bet you have a bad start stop module.

Not sure if this is an issue or not but the ski cranks without the lanyard installed.

See my previous posts for how to bypass the LR-503 Start/Stop module.

[Jonyota]

I bypassed lr503 module and still cranks without lanyard and does not run without start button pressed. With module bypassed it will crank but no start. Does not wake up instrument panel until lanyard is in.

This is expected when Start/Stop module is bypassed.

and does not run without start button pressed.
This is with module bypassed?
If Start button is held down then it 'runs'?

With module bypassed it will crank but no start.

Does not wake up instrument panel until lanyard is in.
This is normal behavior.

I am wondering if the engine is only 'running' on one or two cylinders.

When it starts, does it respond to throttle?
Can you keep it going by apply throttle and then letting go of the Start button?

[Jonyota]

It is running on 2 cylinders. Does not respond to throttle. I can keep it going by dumping fuel into the intake.
