Is there anyway to get a p pump conversion On a 24v and still pass a Cali smog check? Cel light is the problem. You can take the light out yes but they still scan and check for codes so how would one go about fixing that?
 
what causes the CEL to go off? just the pump being unplugged? i would think that maybe you could find a way to make a dummy plug and use wires along with resistors to make the code go away.
 
Nope. Basically, a newer engine would work (common rail) but anything that could be considered older is a no-go. Of course, there's no assurance that the smog people will actually know what they are doing.

This is true but I would need a 12 motor from 98, 98 harnesses, manual ecm and pcm, ect...... Compared to just p pumping what one already has

No ecm, but a pcm and wire harness should do it. It kinda depends on how smart the smog guy is, but there wont be any codes.

My smog guy is dumb as a box of rocks but does infact check for codes hence my topic lol. He passed my twin turbo vp with 7x12s no problem lol

Thank God I don't live in Cali. I don't think I own a vehicle that would pass smog there.
 
I moved here this last winter, I'm up in lake county. I have been wondering this same thing. Quad box has all but toasted the vp, so I would like to p-pump. I can take the truck back home and we can do it at a friends shop no problem, but I don't want to end up with a truck I can't drive out here.

If you start the swap keep me posted on how it goes! Maybe let me know what shop passes it. I'm close to 5 hours from you but it would be worth the drive if it makes it pass.

You got it my friend

So I would use my 24v ecm, and 24v engine harness but use 12v pcm? What 12v harness are you guys referring to and would I need a 98 12v fuse block?

No, use ONLY A 1998 model 12v engine harness, sensors, and PCM. You would reuse nothing from the 24v system, electrically that is.
 
Or does the 98 12v even have a ecm? This is making my brain hurt lol. OK 98 pcm, 98 fuse block, 98 engine harness, I will have to figure out the tach since I won't be using the cam sensor any more. What else would I have to do to eliminate the check engine light

12v balancer and crank sensor... To go with that harness.. Tach will work
