Cali truck?

[F350oldskool]

is there something special thats obvious you have a cali model or not? manufacturer sticker? vin? just seeing stuff on these and just curious

Cali emissions have a GPCM, not a GPR. Not sure about a catalytic converter.

oh yeah i have a GPR, ya it had a cat too. thank goodness for emission borders. haha it had to come off

California trucks with the split-shot injectors (late 96 and 97's ... generally refered to as the Cali Trucks) still have a CAT, but they will have a shunt on the GlowPlug relay to monitor the glowplug bank current. They will also have a pulse dampener on the output (rear end) of the fuel pump. It's a black disc-shaped piece that looks like the "Starship Enterprise". Cheers!

My late 96 Cali had a standard GPR, no shunt. The shunt was only on the 97 models.

there will be a sticker on the valve cover that states it complies with california emissions on the pass side valve cover, thats a pretty big eye sore of a tell tale, and if you want to go through the trouble, pop a vlave cover see what injector code you have

What if someone changed or painted the valve covers? What if someone changed the injectors?
The fuel pump is usually a dead giveaway if the truck is still stock. A shunt on the GPR for the 97 models would be a dead giveaway too. The only 100% surefire way to know is the PCM though. Or, if you've been around these trucks long enough, you can hear the difference between splits and singles at idle.
