What would cause the fuel to fill up the central port for the injectors where the main wire connector plugs in when I try to crank the engine to start the truck? It's like the gas is going in reverse in the spider injectors and the connector pops off and fuel is left in the port.

Hi,

It sounds like a fuel pressure issue. Have you checked pressure? If not, do this first and let me know the results.

I attached the directions below specific to this vehicle for testing. They include diagnostics and fuel pressure specifications.

Let me know what is found.

Take care,

Joe
