My money is still on the cables from trunk, and/or the grounding.
Be careful with that idea. Starters are way stronger than people think. I have seen bent rods and many crushed bearings with lots of battery and interference of some kind. Compression will not break in and if someone set up the clearances that tight, you will have issues after things expand under normal driving conditions. By chance is the coil hooked up when you are spinning it? Is the fuel pump running as well? Are you certain that ign timing and cam timing is right? Spark plugs interfering mechanically?Pull the valve cover and spin the engine over without plugs to see if all valves are opening correctly and in the correct sequence.
I think you would've noticed, but a possibility is if a faulty injector/injector wiring/ecu fills up a cylinder with fuel as soon as you move your key to start = hydrolock with plugs in.
I had this problem once, but the smell of fuel should be noticeable which I think you should have noticed.
Sounds like a great way to bend a rod!

It sure is, it happened twice in a Volvo 245 TIC that I had, the problem was a sketchy megasquirt setup, and impossible to notice since it happened for no reason and you wont hear it from inside the car.
Luckily, no rods were bent in my case! (But would have if I kept bringing more batteries )
thanks just trying to turn it over
