When you say it doesn't start, I assume it cranks but does not fire. If this is the case, then we need to check spark and fuel. You also need compression but let's start with spark and fuel.

If you take starter fluid and spray it in the intake, does it start? If so, we need to monitor fuel pressure and see if you have any pressure.

If it doesn't then pull a spark plug and hold it against the block with it hooked up and see if it sparks when you crank the engine.

Let me know what you find and we can go from there. Thanks
