The engine starts in the start position but dies after 3 seconds in the run position consistantly. I have cleaned the maf and that code did not come back but the problem is the same.

Hello,

It sounds like a fuel issue. The engine is likely not getting enough fuel.
In order for the engine to run the fuel pressure has to be adequate. You can have fuel pressure issue if there is a restriction in the fuel line like a dirty fuel filter or the pressure regulator is not functioning properly.

Check the fuel pressure, it should be at 37-46 PSI.

A dirty fuel filter will restrict the fuel flow to the injectors.

I have attached diagrams for your reference.

Please let me know of any questions.
Thank you.
