so I took my car to a garage and they fixed the problems I was having before and I have had for like a week with no problems. Now today I went down to move it and it started fine and then I parked it. I later about an hour after I went to leave and it wont start. There is no crank and the starter isnt engaging. I used a jumper wire to the starter and it cranked fine and tried to start. But I still get nothing with the key. It has a new vats module, key cylinder, and matching vats key. Cant figure this one out guys please help. And there is one more problem. When the car gets up to temp it runs fine till I come to a stop light the oil pressure drops and it stalls out. I thought it was my oil was bad cus its due for an oil change.i changed the oil and it still does it.

 

 

IT was an electrical shop and,they said it was my nuetral saftey switch. They also added a inline fuse wire to the starter. I checked that fuse and all the other fuses and they are all fine. They also took a ground wire and put it to the body of my ecm and then to the frame which makes no sense to me.
