It does try to turn the engine over....but it’s almost like it don’t have the power! I put new batteries and heavy duty cables on it and it does the same thing. I’m pretty sure that there’s fuel in the oil again because the oil is REALLY thin and I use ROTEX oil! I’m like you though...it may be starter is just too weak to turn that engine over. Gonna do more troubleshooting on it todayDoes the starter turn over the engine. If it does not check the starter to make sure it is all okay. If it is don’t try and start the engine. Remove all the injectors and then roll over to expel any fluid. Then figure where the fluid is coming from and fix that.
If there is fluid lock and the engine starts it can cause serious damage.
