There is a lot to stay on top of in between sessions, end of day, and prep for the next event. A good list can be found in the owners manual which is...

I keep wondering whether I have a similar issue, maybe not due to the starter motor but something else?

Swapping the throttle bodies did not help isolate the problem. I swapped throttle bodies on both cars. The problem car had the same problem -- fires...

I just removed the throttle body from the bad car. I noticed that the injector for number 1 cylinder has about 2mm up/down play in it, whereas the oth...

I swapped ECU from bad car to good car. Good car runs well after the ECU swap, so rule out the ECU. I think I have one or two more obvious items to...

Thanks Charlie for the suggestion however I can no longer get the engine to run without or with additional throttle. Just an occasional brief fire an...

Rule out fuel. I have another SR3 XX and I swapped fuel between the two. The other SR3 runs fine with the swapped fuel, but the problem SR3 still ha...

@rlm-dan Lots of things to try. I have not had time to look at it since a week ago, so I have not checked spark plugs yet. I had not thought abou...

Thanks everyone for your thoughtful posts. @rjbender -- I put 6 gallons of fuel in the cell. When I did a purge the flow was strong. @parsonsj -...

It will start right away. I don't have to cycle the master switch to get it to fire multiple times.

rpm looks right in the data. Thanks, I will look at the spark advance. I didn't know it logged that.

@parsonsj Thanks John. TPS stays the same -- 4.1%. Some new info ... I put a zip tie end between the throttle and idle adjustment screw. This ...
