Alright, another update time.

the MAP sensor is also shot.

I tried getting a spark, connecting a sparkplug to the ignition bar to a ground and starting, no spark, so must be ignition problem.

starter, crankshaft position sensor, camshaft position sensor, battery, all work. so ASD (auto shutdown) relay or pcm?
is this a good test on the relay?

i guess it is down to those 2 because i believe oil pump drive and drive gear have nothing to do with spark...
