Sounds like it wants to start but backfires through carborator instead. I have installed new plugs, new coil, new wires, new gas filter.but it will not stay running. You can start it by poping the clutch and it will run for a while then just dies. any thoughts?

 

It sounds like it could be the fuel pump. I would check the fuel pressure to see if it is pumping the minimum pressure needed to open the fuel injectors.

 

Oil under distributor cap. Replaced distributor car runs great.
