90 FORD F150 PICKUP STARTS HARD, THEN DIES
 

it's a ford f150, '90 302 EFI engine. truck starts hard, runs for
about half a minute, then dies. then it won't start again. if i do
get it going again it runs very rough and dies again

changed the fuel filter, changed air filter, cleaned the IAC

tested fuel pressure on the rail i get 22psi whether i turn the key to
engage the pump or the starter.

looked at the vacuum lines didn't smell/see any gas.

any ideas what could make it so hard to start and cut out like that.

I believe 22 psi for this engine is low, check those specs.
