and then it wouldn't start or nothing, long story short we tried to figure out what all was wrong with the car, narrowed it down to the injectors spraying all at the same time, I am so lost as to what would cause this that I have unplugged my emanage ultimate and reverted it back to the stock ecu settings and it still does this. I am thinking about buying a new ecu that works and see what that does. Does anyone have any idea what could cause this and/or how to figure out how to fix it, I would greatly appreciate it.
Injector Problem
Injector Problem
Hi, I have a ka-t with 440's in it and I was out in a race back in June time frame and my car was running hot so I pulled in the pits to let it cool down and noticed that my car was dripping fuel out the test pipe soo I was like and then it wouldn't start or nothing, long story short we tried to figure out what all was wrong with the car, narrowed it down to the injectors spraying all at the same time, I am so lost as to what would cause this that I have unplugged my emanage ultimate and reverted it back to the stock ecu settings and it still does this. I am thinking about buying a new ecu that works and see what that does. Does anyone have any idea what could cause this and/or how to figure out how to fix it, I would greatly appreciate it.

Re: Injector Problem
I would check the fuel injector o rings first. If a lower ring is leaking it will result in a lot of fuel being dumped into the engine.
Re: Injector Problem
I have switched injectors to the Sr's and it still fires all of them at the same time. It has to do with the timing of the injector, is that controlled by the ecu or something different.

Re: Injector Problem
I would be looking for damage to the wiring harness. The injectors have 12v constant too them at all time. Its the ecu that grounds them, for them to fire. If you have a section of harness that is damaged causing the injector signal wires to touch, when one fires, they all fire.
Re: Injector Problem
Try checking you timing yet?
