hi first my car is getting no oil pressure on the gauge i just changed the oil the oil return line gasket and the oil filter and now i get no oil pressure. The thing is i use to get pressure before can any bodi tell me where to look.

Oh and when i start my car it dies unless i have my foot on the gas then it finally hold a idle when the car warms up. this wasent a problem before but now that its getting cold i need it to start and warm up by its self help please.

 

You probably disconnected the clip on the oil pressure sender. It's the mushroom shaped thing right underneath the oil filter. It has a single wire (yellow/red I think).

Does the car have the stock coldstart components? BAC, thermowax, etc...
