02 v6 issues

[Apexmaster]

hi guys, I have 2002 explorer with 4.0, I can get it to start no issues, after 30sec it just dies. I have brand new alternator, air filter, plugs, wires, thermostat. engine has 200k
any ideas?
no CEL of any kind.
I do have fuel and fuel pressure of 60psi.

You may not have a CEL, but you likely have STORED trouble codes in memory unless you disconnected the battery and cleared them. Did you scan for DTC's using a handheld reader or Forscan?

After it dies do you recheck the fuel pressure? These fuel pumps have a check valve in them that can get stuck in the return position. '02's have a return line from the fuel filter and after the fuel pump senses enough pressure in the line it opens a check valve that may be sticking open.Just a thought.Lack of fuel pressure does not set a code on '02's either.
