Just won a retro-fit kit to change-out the points on the 4a032 to electronic on E-BAY for cheap money ($17+ shipped). Box was unopened with all parts still in the bags, but no instructions. Figured that it can't be too hard so installed on Saturday. Now engine only runs on #1 & #2 cylinders, but has spark on #3 & #4. Anyone have any ideas? How about the instruction sheet? Even tried the old rotor for the coils, no change.

If it is a bad controller (which I assume is the little black pod inside the coil case, one per side), why would I have spark on the two cylinders that won't run? How did you correct yours, and did it take two controllers?

Got a new module. What happens, is they will still show spark, but its either too weak to fire, or timed wrong. I had bought mine from saturn... and they hooked me right up.

Ace can flog me with a wet manual!!

Since I did not have any instructions with the new kit & did not download the manual yet, when the coils are marked "top" I installed them that way. WRONG!! Per the manual, the righthand coil must be installed with "top" down and wired per the manual!! Right coil controls the left mounted secondary coils and must be the source of the problem. Will know better tonight.

Well, last night I reversed the right hand coil per the manual. Engine started on third pull and after clearing the lazy cylinders from before, ran great. Next time something is labeled "top" don't believe it!
