You have had the car for 1 month. Not is ruled out.
Start from the beginning.
First what is your mechanical and technical background on working on vehicles?
I needed a scope fast and this was cheap (was less then $30). It read the cmp on the other car fine. Unfortunately it is just a single channel so you can't compare ckp and cmp on the same screen. I'm looking at getting a multichannel one...
pull down design. Read up on it.
Plus did you check what I posted?
Don't bother with the gas pedal to the floor. Vehicles are engineered to have a 'flood clear' mode that cuts fuel on cranking when activated by WOT on crank.
You can check the ground pin on the MAP or throttle position sensor as they are easily accessible as they all tie to the same pin on the PCM as the ckp and cmp. The ground signal for all of them is on the same circuit. It is NOT chassis ground but PCM ground. There is a big difference hence...
Just making people who stumble on the thread to be aware the PCM has the voltage regulator.
There is a procedure in the SM about testing it at the output post.
