Need Startup Help
91jeep, the instructions provided in the box explain in detail how to do initial startup and set the IAC. I assumed you read those and followed the steps.
What box?
Today's Update
Last night, I screwed the idle screw in about 3 turns and it cranked up and idled at about 1100 rpm. TPS at 5.0. Waited till the idle came down to about 800 and the temp was up to 170. Backed off on the screw till the idle came down to about 700. TPS at 3.0. Shut down the engine and let the tune save. Turned the switch back on and checked the TPS. It was at 0.0. Cranked the engine and started well. Idled good and when the idle settled out at about 700, the TPS was at 0.0 to 0.3 and the IAC was at 0 most of the time and periodically it might show a 1.
Now today, going to try a cold start without any mechanical manipulation and see how it goes.
You don't have the installation instruction that came in the box when you bought the unit?
Fyi. IAC should be around 15-20 steps when at idle and warmed up....
Yes, and read it at lest 50 times. It is very lacking. The only thing is says is put this part here and this wire there and crank it. That's all.
Like I said, I did all of that according to the instructions in "The Box" and it would not start. Had to remove ALL the wiring to get back to only what is required for the engine to crank and start from there. The instructions do not have any trouble shooting steps when the engine does not crank. Does not say anything about checking the coil harnesses to make sure they are on the right side. Nothing about crank sensor, nothing about how many rpm should be seen on the handheld during cranking. That is where my recommendations for a flow chart start. When the engine does not start. All of the issues that individuals have had and their solutions could be added to the chart over time, and eventually, almost all possible things that could go wrong would be in the chart for the next person to see.
The way I understand it, the idle screw was the problem the whole time. Am I missing something?
