Well for that last little while i have been having a little trouble getting the car to start. Its just been cranking for a while before it finally decides to start. So today i go to start it and it starts to crank, but then it abruptly stops. Go to try and start it again, and it acts like it wants to crank but stops very abruptly again. It almost seems like something its getting caught in the process and not allowing it to crank over. The battery is great and electrical system is all fully charged so i know its not that. Any thoughts on what might be going on would be great. Thank you in advance!

So the car won't turn over, or it is but isn't starting? If you think the electrical is all good, I would suggest first to clean and free of corrosion all your visible connectors, PTU connector ect., make sure your batt. terminals are clean and not loose and check for any breaks in the wire where they could have rubbed or got to hot and melted not very likely but possible.. Also if it starts to turn over and than stops after you check all the connectors you can get too, next step would be the starter. Easy test if you can get to it would be to jump the terminals on the solenoid. If you notice the same type of issue as when turning the key, you found your problem bad starter/solenoid. If you're not careful when doing this test it will sometimes weld whatever tool your using or at least leave a nasty mark on it and whatever it touches when you jump the starter solenoid, use caution.
