The engine light came on in my daughters car. We put it on the computer and it was the EGR solenoid. We replaced that and the EGR valve. The car would crank and run fine until it warmed up. When it gets warm, it dies and will turn over but not crank. We plugged off the vacuum on the valve and the car ran just fine for about 6 months. Now it is doing the same thing. Is there anything else we can try?

It is not showing any codes. The fuel pressure is fine.

fuel pressure must be 38 psi minimum wvacuum and 47-50 wthout. if no codes check cam and crank sensors for resistance if fp is up to specs.
