No start when hot

Good morning,

When it will not start, I would check the fuel pressure. Chances are the fuel pump is failing when it gets hot.

The pressure specs are below for you. You can rent a tester at a parts store.

FUEL PRESSURE
1. Ignition "OFF" for 10 Seconds.
2. With ignition "ON," engine "OFF" and fuel pump running, pressure should be 385-430 kPa (56-62 psi).
