Have you checked compression? Obviously it should be good, but bad things can happen to new parts.
just looked at it and my spark starts at 10, then jumps up to 24 after it starts(follows rpms), then drops to -4 until it goes into closed loop.
One thing I thought was strange on my car, is the fuel pump voltage spikes to 25 volts during cranking. No one ever did explain that to me.
Thank you for checking.
My fuel gauge goes to 80lbs when cranking. Compression is still good.
Crank and cam sensor good. Throttle body good. Maf good. Voltage good. Have fuel pressure. Injectors are pulsing. Cop's have 12 volts. No cop pulse.
Stinks, but I think the only thing it can be is the pcm...
I was trying to work out a transient fuel issue and I was loading tunes one after another.
Maybe the pcm overheated?
Ended up doing molding today instead of driving the car. Blah
