evinrude spark issue

[oldboat1]

Should have full continuity on each plug wire, spring clip to spring clip. If not, rebuild the wires (replace the wire and the spring clip, and check again for continuity.)

must use an open air adjustable spark tester, not the inline type. The engine has to turn over at 250+ rpm to fire up the engine. You may have a weak battery or a starter that needs to be cleaned/rebuilt.

the starter is fine as the battery. i can take it to the lake tomorrow and run all day on 2 cylinders. it starts and cranks fine./ its no longer a spark issue. its cylinders 2 and 4 not detonating. ignition system its all new.

as in post #2 swap 1&3 spark plugs plug wires power packs coils and wires may help good luck with the 2&4 that are not running

the coils and pack in 2 and 4 is new sparking fine. i swapped 2 and 4 just to check but was a no go. they are not reversed. i was very careful not to swap when i replaced coils. i tried it to rule it out. backfired and wouldnt start when i pulled 1 and 3 wires and isolated 2 and 4.
