Random starter trouble

Question has this car ever had a aftermarket security system added ?
I ask because a girl friend of mine had a similar problem with a little Nissan pick up truck. She/we never knew the remnants of such a security system was still wired in under the dash. It wasn't discovered until after I installed a new starter.
Funny thing is.. For a couple years She had got out and rocked the truck. All she really needed to do was open and close the drivers door again. Cycling the dome lamp circuit was resetting the security unit.
I really don't think your turning the engine by hand is having any effect on the electrical operation of the starter.

No, not to my knowledge and I have been under the dash several times but have not seen any wiring of that sort. I have to turn over the engine sometimes because the starter has engaged, but not fully, and then it wont snapp back. It's a little hard for me to explain, english not being my language. Thanks for the input!

If all the electrical dies when this happens its likely an issue with the positive or negative cables and or their associated connection. Look at both battery connections ( also actual battery posts. One may be loose), negative to engine and chassis etc...

Thanks, I will go through everything again thoroughly. I have been wanting to buy a mini starter because I thought it was the starter, but it's unnecessary to spend the money if it really is the wiring of course.
