'92 400E no start
400E No Start
o.k...here 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. H..E..L..P! |
