Hi all, new to this forum thing.
I have a 1992 cherokee larado, 4.0L, Automatic 4X4, all stock. Has lots of miles on it. I have been having trouble with it now for over 3 months. I have read everything I can find on line about these problems, so to make a long story short, I have replaced PCM,CPS,TPS,Fuel Pump,fuel filter,ignition coil,disteributor,rotor,cap,wires,plugs,battery,ba ttery cables,took the MAP off and cleaned it reinstalled. Unrealated, I replaced the valve cover gasket. Air filter is new I installed a fuel presure guage on the rail (a copy cat move from a forum paste). My pressure reads 31lbs constant before during and after the problem occurs. Problem...It will not stay running. It will die just like some one shut off the key,at any RPM in gear or not, going down the road or sitting in the driveway. After further reading I am looking now at the possibility of KNOCK SENSER, IAC, or re..replacing the cps. Anyone have any other ideas?

Mine is around 75 when cold, 40-60 when driving, and 20 at hot idle. From my experience this is the normal ranges

I'm not entirely familiar with '94 Cherokees but, since the headlamp switch is a multi-function switch (which also controls dash lights), then you might want to replace it.

no that sounds about right - maybe a little high. Spec is no less than 13psi at HOT idle, 37-75psi above 1600 rpm. Oil pressure should (and will) decrease as the engine oil warms up to operating temp - "HOT" idle in this case means engine oil fully warmed up (15-20 minutes of driving).
