Hello. My name is Tan.

We must start with a compression test to eliminate any kind of compression issue.

Have you done and fuel filter changes yet? Then finally if we find these are good then we must be able to put the engine on a scanner if this is a MPI fuel injection engine.

Can you do these checks?
