Perplexed by timing situation - Page 2 - Infamous Nissan

Should I have disconnected the TPS as part of the timing chain replacement process to begin with? Could the ignition timing being off cause the engine to shake?

My problems didn't start until I replaced a guide and put the chain back on off by a tooth. When I took the timing cover off, the chain was indeed off a tooth on the crank sprocket. I would be shocked if the issue wasn't timing related.

Should I have disconnected the TPS when putting everything back together? Could ignition timing being off cause the engine to shake? Makes the whole truck vibrate.

My issues didn't start until I replaced a guide and put the chain back on a tooth off. When I took the timing cover off, the chain was indeed off a tooth on the crack sprocket. I would be shocked if the issue wasn't timing related.

You just need to disconnect the TPS while you’re adjusting the timing with the timing light. Warm the engine to operating temperature, turn it off, disconnect the tps, connect the timing light, crank the engine and adjust

So that probably explains why I can't start it now...

I had rotated the distributor slightly without disconnecting the TPS to see if it would settle the engine, but no real difference, I then went to try to back the truck up a little, it stalled and died. Now it won't start. I thought maybe the new spark plugs and wires I put in were faulty so I changed them out for the old ones, but that made no difference.

My oil level is good, but I'm now smelling gas in the crank case....

Was getting a choppy exhaust and white smoke coming out of the exhaust pipe and from around the exhaust manifold. I did spill a little oil on the manifold.
