i got fooled last week, the car had a no start, v6 ford had fuel and a weak spark i just used a screwdriver to check the spark against the block, changed the moduel no luck same thing ! got my spark tester out( u can buy one at any parts store,) tryed that no spark! changed coil varoom! just a weak spark from a tyred coil/pickup coils will also get soft and mushy and or poor connection where the moduel pushs in. u could do a ohm meter check on the pickup coil, but it's nice to have a good one with you to compare it too.
