Agreed, and as an add on and was mentioned earlier but not in this post, you will probably still have to replace your plugs as they are most likely fouled anyway. So even with the temporary 12v hooked up, you may still not get it to fire until those plugs are changed also.
Sounds good. Thanks again. Ill upload a pic of this wire tho for the sake of it. In case anything visual can tell you anything in the meantime
Yeah that was my takeaway from it. Fair enough. Well, while everyones here... Suggested plugs and gaps? There's ngks in it currently.
NGK (6630) UR-4 gapped at .045 https://www.rockauto.com/en/parts/ngk,6630,spark+plug,7212 Yes, if you open up the harness and trace that pink wire back to the firewall, you should see where the yellow wire from the starter solenoid joins it and extends to the firewall. You need to replace that wire with 12 gauge wire. You can eliminate the yellow wire from the starter.
Ok. Battery freshly charged. I may have been testing the ignition in the wrong position yesterday like an idiot. So however its reading 12.4 in "run" and drops down to 9 before getting back to 11 under cranking. Ill pull the plugs here shortly and report my findings
Havent torn apart the loom yet but could the wiring have been done correctly than? Had a feeling we tied everything in as it was when we installed the new harness tbh.
Well they say Carquest on em so couldnt be original, lol. Yeah... I suppose ill swap em out tho. Tryna save some money. Never happens.
8 outta 8 like that. Some worse than others. Had to persuade em out w the jack handle. I was careful tho. Had liquid wrench sittin for like 5 or 6 hrs. Anyway! So. New wires ya think? Those boots or whatever were separating like i photo'd but can always stick em back together!
Stick em back together for now, but if the problem doesn't go away, there's only a few things you can change after you fix the resistance wire and get new plugs. Like Larry said, get a wire and jump it from the positive of the battery to the ignition hot side of the HEI with your new plugs. It should run like a new engine after that. You could even put in an inline "on-off" switch if you wanted to get fancy while testing.
Fair point. 12g? Also, anything i had ought to do before i put the new plugs in? Theres still a good amount of liquid wrench around im gonna wipe w a rag and ive heard not to put anti seize on the new plugs.
