'92 400E no start

400E No Start goes. '92 400E was/is having problem with ABS/ASR lites coming on after rolling a few feet.

started to try diagnosing wheel sensors, etc. and pulled all computer modules out of module box to check contacts for corrosion, etc.

got readings from sensors, ( had to move connector blocks a good bit), sprayed contacts & put modules back in box.

now, in addition to same fault lites, the car will not start. starter cranks, but no start. fuel pumps do not power-up when key is turned on. checked pump relay ( under rear seat) and extremely faint voltage there. jumped pins & fuel pumps work fine.

also, at diagnostic connector on module box, no voltage at pin #3.
