try and advance timing it should help with perform
Check for spark and fuel supply. Check the fuel pressure. The fuel pump should run for a second or so when you turn the key to 'ON.'
It's getting fuel.someone told me it could be my starter.
The most common failure producing the symptoms you have described is the Distributor Pickup Plate. It is located within the distributor and can be change simply by removing the Cap and Rotor and lifted out.
