As soon as it starts it shut off

Hello,

This could be due to a weak fuel pressure as the fuel pump is unable to provide enough fuel to keep the engine running.
Low fuel pressure can be due to a faulty fuel pressure regulator, restriction in the fuel line or a weak fuel pump.
Test the fuel pump by using a test gauge. This vehicle should have 43 PSI of fuel pressure.
