Ok so Im confused, maybe someone can clear this up. I have a 91 silverado w305sbc Im having trouble as in no spark,no start etc. The book says when you ohm the pickup module it should read 500/1500 mine reads 880, this is a new pickup coil, the old pickup coil reads the same. Now I read that the pickup coil should read infinity on the high scale if not, its a bad pickup coil. Now what gives, is my new pickup coil bad or good with the readings I have, thanks for any help.
