injector pressure?
what should the injector pressure be at idel on our trucks. hooked mine up to the obdII today and the only code i got was cps intermintent. pressure was verying from 850-880 psi. been having a lot of white smoke since i bought it and wondering if it was injectors. unfortunatly the geniss wouldnt do a buzz test.

I guess your talking about ICP. lol. ICP at idle should be anywhere from 650-850psi. Never looked at ICP on a stock truck before, but have seen those numbers range like that on tuned trucks. Your ICP is good. Is your tach moving on startup? CPS would be a good thing to change either way since they are cheap and you need a spare anyways.

yeah i was looking in the glove box and theres two in there. go figure! its not a bad truck just smokes like hell at start up for about 5 min. its a old vol. firetruck. figured it be one hell of a pull truck. 4x4 with a zf5. seems like it has so little power but it may just be the fact that my truck isnt so stock and im used to it.

An old fire truck may be a clue.
Most times the actual miles on the odometer are fairly low, but the engine has many hours running but not moving while at accidents and fires.
Depending on exactly what it was set up to do, the RPM's could have been anything from idle to rather high the entire time it sat there.
The local volunteer fire department runs in the station, starts the trucks, 30 seconds later wide open throttle on a rather heavily loaded truck till they get to what ever incident they are responding to.
Not exactly the ideal way to warm up the engine.
