I'm in what I was hoping was the home stretch of my 302 rebuild but the damn thing will not start. After final assembly I powered it up and tried to start it however it wouldn't turn over so I replaced the starter and solenoid and it started trying to turn over but wouldn't start so I tried to manually turn the crank and felt too much resistance so I pulled the spark plugs and fuel came flowing out so I killed the power. I pulled out all the injectors and tested them they all had 14.4 Ohms of resistance and all had fuel in them and clicked and released it when jumped. So I checked and the 4 that were open shared a ground so I found the short and now the excessive fuel flow stopped. The crack was spinning freely before I put the spark plugs back in however now with the plugs back in it will no longer turn over. I'm wondering if I have to much compression or if anyone knows what the issue could be?
