what is the PSI for the fuel pressure? Also my truck shut off on me while driving on the freeway. When I got home from towing it, it started right up. About 5 minutes later it would not start. It turns over but does not start. I have changed the fuel pump twice already. Any ideas?

Hello,
The fuel pressure should be 55-62 PSI with key on and engine off.

It sounds like you might have a faulty crank position sensor.
When a crank position sensor goes bad, the engine can stall without any warning and usually you won't be able to start it back up. Sometime it might start when the engine cools down some.

On this vehicle you will have to remove the starter to access the crank sensor.

I have attached the replacement procedure for your reference.

Please let me know of any questions.

Thank you.
