Cranks does not start

Hi,

The P0455 (large EVAP leak) won't prevent it from starting. Have you checked for spark and fuel to the engine? The easiest thing to do is see if it starts for a couple seconds using starting fluid. If it does, then we know it's a fuel related issue. If it won't start with starting fluid, then it's likely ignition related.

If you feel uncomfortable using starting fluid, here are two links that show how to check for spark and fuel:

Try this and let me know what you find.

Hi,

No, the oil won't affect a large EVAP leak. Did you check for fuel pressure? I noted you ordered a new pump. Did the engine start with starting fluid?

Let me know.

Joe

Yep, it needs replaced. It should be between 50 and 60 psi. The fuel tank needs removed to replace it. Here are directions for tank removal and replacement and pump replacement. All attached pics correlate with the directions.
