yeah im sorry, i missed that. i read "icm changed and same prob." i missed the cleared part. whoops.
but any way...fuel pressure is good. and you added water to the crank sensor? how exactly did you add water?
and when it dies the engine has no spark at all. is the ses light still remaining clear? this has to be a loose connection. if you got a faulty sensor out of the box, why would it do the exact same thing as the old sensor? i would guess that its a connection problem on one of the pins,maybe.
first i would check the harness on the crank sensor for corrosion if looks good, you could check the pins from the sensor plug to the icm harness. and then from the icm harness to the pcm harness.
crank sensor to ICM
pin A ----------------- pin H (sync sig in)
pin B ----------------- pin G (cs sig in)
pin C ----------------- pin M (sens ground)
pin D ----------------- pin N (sens feed)
ICM to PCM
pin C------- pin D6, grn harness (spark ref)
pin D------- pin C11, 32 pin blk harness
all should be close to zero ohms
here is a schematic for the icm and cps.
***please note this is for the W body project in my sig. Ignore the pcm pins. the icm pins are the same, but follow the pins stated above for the pcm! ***
