Ok lets see i put in new starter new alternator and changed out the main relay car runs fine but heres the catch once i turn it off it wont start back up without a jump and when i jump it starts right back up like litteraly within seconds so what could be the problem im low on cash and cant afford to take it to the shop so any help all advice is considered good/bad

 

service the battery

 

Also brand new battery

 

check all of your cable to and from the starter and alt. make sure none of the wires look broken/loose/or corroded (green or swollen at any points. Sounds to me like you're dropping some voltage somewhere in your starting circuit and it's only getting better once you kick up the amperage. Check all the elec. connections over really well in your starting system.

 

So good news checked all my connections and got it to fire up great took it out for a run came back let it sit and started right back up so thanks for all the help
