I am having a crank no start problem. The car died while driving on the hwy. I towed it home. I have compression, and spark, and fuel pressure with key on is 51psi. I found some information that at idle it should be at 37, but that seems high for TBI. So I guess what I want to know is what should fuel pressure be with key on not running?

 

you can only check the fuel pressure while its running, with the vacuum line removed it should have 40-50 psi.

it sounds like fuel probably isnt your problem.
are you getting any CEL codes?

 

Nope no CEL light. The injectors ohmed out ok, and I have spark. It ran for like 5 seconds when I tried to start it today. I am out of ideas.
