What to check next
Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.
Identify the engine and obtain current diagnostic codes before deciding which component to replace. Have the starting-and-stalling behavior assessed and the proposed fuel-delivery check performed using the correct equipment and vehicle specifications. Return with the codes and measured results so the next step can be based on evidence. The thread does not establish a failed fuel pump or another specific cause.

Do you have access to a scanner? They are around $20 on Amazon and should be the first step in tackling the issue. It will help inform of any trouble codes in the memory. Next step is that we need to check that fuel is being delivered to the rail and is pressurized. Please let us know.
