    I see a tech section for Gen 2. Is a there a tech section for the Gen 1? It's strange it seems Gen 1 forum is inside the Gen 2 forum and there is no dedicated top level subforum for the Gen 1.

    Something we can take up with the mods? Doesn't seem like it'll be hard to do.

    No, this is (see picture) Taken from under the car in front of the passenger side back tire.

    If you have bad gas in it, it is not going to combust. ICE will run like garbage. I tried running straight injector cleaner fluid in mine. injector fluid will not run an ICE by itself. it needs new GAS.

    P3191 always means the engine does not start.

    You know you put bad gas in it. Get the bad gas out of it.

    cheapest and easiest thing to try is: Clean mass air flow sensor.

    Here are some help full pics 20200611_094545.jpg 20200611_094523.jpg 20200611_094454.jpg 20200611_094429.jpg I found on the web

    I thought you said the engine was not running. This will let you see if 1. the fuel pump is working ( you are correct, gas will not get to the engine if it comes out in the pan under the car.) 2. you can inspect the gas in the catch pan under the car for water and flammability. ( i wouldn't be smoking when you do this).

    Jet fuel is kerosene. Or, did you mean AvGas aka 100LL?

    I was thinking it might be easier to disconnect the fuel line from the front of the car then engage the fuel pump somehow. I think it can be done by shorting the C Opn relay based on what I've seen.

    So I think I found the quick disconnect line. It's surround by the different components so I couldn't really get a grip around it. I also didn't want to put too much pressure and break something. Is it supposed to disconnect at the red line or blue line in this pic?

    Not sure why they put it there. Can't really fit my hand in there to disconnect it. Might need a special plier to push and pull and the same time.

    Also pulled the EFI relay. Not sure if I'm supposed to short the orange or yellow leads to energize the pump.
