[Monkey Wrench]

easy enough to siphon your gas and refill, you can check the fuel delivery rate by extending a hose and put that in a gas can, run the pump to make sure you have enough flow. the rate is documented. you can observe the fuel injecting and that it shuts off from the injectors with fuel rail removed BUT be very careful, no one wants to prompt you do unsafe things. Know the risks, have appropriate extinguisher at the ready.( not a water hose) take the car outside..

I have a friend that drained gas tripped on a trouble light he created a serious fire ,lost his shop some nice cars and now his face is badly scarred and he has basically PTSD from that too.. No car is worth all that.


I think you can choose various fuel maps but Others can advise on that. You can read the plugs for wet gas or carboned up etc. see if one is bad.

at idle there is only so much air entering , if it can find way past the AMM into the engine by a loose cracked hose or manifold leak then the engine wont inject enough fuel because this air wasn't measured by the AMM.

the pulse from the computer gets amplified by the power stage ( amplifier or transistor) before the coil's primary winding. , maybe if that failed it could have a weakened or intermittent spark. I'd clean those connections and check grounding in that area too.

If you attempt to change multiple things at once and then have issues that can be confusing so maybe you can revert back , Not to call the whole thing a fail, but just to verify everything except the mod you are working on is functional and verify that you aren't off on some troubleshooting tangent due to some unrelated issue.
