Now I just bought a 97 1500 with the 5.9. I realized that when the number 1 cylinder is at TDC, the rotor is actually pointing to number 8 cylinder.. so I had to change my wires on the cap just so the truck will actually run. Now my question is, I understand the ecm controls ignition timing. So if I move the distributor so everything lines up correct, what are the issues I'll have with my fuel sync and ignition timing?

 

The pcm adjusts timing. Moving the dizzy adjusts the fuel sync. #1 cylinder needs to be on tdc of the compression stroke. Adjust the dizzy like this...

 

But is moving the distributor gonna mess up my fuel sync?

 

Absolutely

 

Do you think it's possible that somebody never got the fuel sync reset when they moved that distributor?

 

Entirely possible. You need to reset everything so it all lines up properly. That will get you in the ballpark. Any shop with a decent scanner should be able to set sync for you.

 

No need to resync. It runs like a dream! Way better than when I bought it last week. Moving that distributor did wonders honestly. Now I have to fix my p0443. And then I can take it to emissions and get her plated!

 

Still wouldn't hurt to have sync checked..... Just to be sure. You get a total window of 14 degrees.... (+-7)

P0443 Evap Purge Solenoid Circ

Purge solenoid on yours is at the back of the intake manifold, drivers side. Make sure it is plugged in, and all the vacuum lines hooked up.

 

My buddy had a snap on. I'll Def get it checked when I get it plated just to make sure. As for the purge valve. I threw a new one on along with the canister already because the charcoal was all in the lines. Cleared the lines. Code came back. We'll first time it was a p0441. Now it's the p0443 for the circuit control. I just popped the new one off, stuck open again.. so I made sure nothing else was in the lines and no they were clean. So I got it swapped. Gonna throw it on and make sure I'm getting voltage at my harness. Hopefully all goes well!😊
