200 ZJ fuel pressure???
 

4.0- 6 cyl,,,,what should the fuel pressure be at the injector manifold?

32psi for the 93ZJ 4.0 Yours should be similar but since they changed in 2000
can't say for sure.

50psi +/-2,3psi should hold 10 psi overnite if not then something is wrong

The older 4.0 spec'd 40 PSI w/o engine vacuum, 32 PSI with vacuum but
what ever the number I'd like to know where the 10 PSI overnight leak
down value comes from. I KNOW I've seen it somewhere but the FSM I
have only says no more than a 10 PSI droop sitting off for 10 minutes.
Even with the older unit I have I still have 15 PSI or so after
sitting for a day but I would sure like to find the source if that is
a spec for overnight leakdown.
