I'm thinking it's something else cause of how slow it cranks, and figured out that the crank doesn't want to rotate by hand only with a wrench, and that's with no spark plugs and no distributor.
it is cranking extremely slow. So I took out the starter and battery and had them both tested and they both passed. I'm not sure what else it could be at this point
Like the title says I need some help getting my 510 started its got a freshly built ka24de out of a 95 240 and everything is wired up correctly to the best of my knowledge. It has fuel pressure and spark. If anyone could come give me a hand that knows these motors it would be greatly appreciated!!! There's some beer in it too for whoever wants to give me a hand.
