2002 Chevy Express 5.7
Starts and dies fuel pressure 50-55 sometimes goes to 60
Security Light is not on it starts and does have changed spider injection and lots of others things
back to the story I purchased this van got it home on rollback started it and drove it down the road then it started acting like it was running out of fuel made it back home and won’t start every since just starts and dies please help

 

Such as? How long ago? OEM parts?

Is the air filter clean? Run diagnostics?
try an exhaust backpressure test.

 

Yes oem parts and that was today I switched everything I’m just curious what all has to be connected to complete the circuit to start I don’t know where to start have tried everything

 

well you need to be more specific than "everything". I just gave you a bunch of suggestions where to start.

 

Yes Air filter is clean have run diagnostic fuel pressure seems to be good 55-60 Psi
changed spider injection
Changed distributor
Changed ignition control module and coil
have not done a exhaust back pressure test how do I pursue that test and any other things you can possibly lead me to than what I just listed

 

Will run if I pour gas on air filter so definitely makes me think is fuel related I’ll wait to see what you think and what direction to go

 

You can do a preliminary poor mans cat.con. test by simply removing upstream O2 sensors and see if it still dies.

Some more info would be helpful, like under what conditions the engine dies....

 

Sorry lol did not mention this when I purchased this van the converters have been cut so don’t have no O2 Sensor you will probably say that’s the cause but why was I able to start and drive it one time then all of a sudden this happened?

 

I agree, that does sound fuel related. Under what conditions did you record that fuel pressure? Did you try to continue monitoring as you drive down the road under various accelerator pedal positions and loads?

 

It fired each time I crank it starts and dies will not take no fuel
