What should my ignition timing advance be at idle in closed loop on a 2000 S-10 4.3 SFI?
I'm pretty sure timing is all done by the computer. It pretty much does not matter where you turn the distributor to, the computer will compensate. The Lean codes you have are typically fuel pressure or MAF sensor. Since fuel pressure is apparently good, you might consider the MAF. It would be worth checking fuel pressure regulator. I have also seen O2 sensors create those codes as they have a lot to do with fuel/air mixture.
Hope that helps.
How do I bypass security passlock 1 on a 2000 chevy s10 ?
It may be simpler to fix the problem than to bypass it. The GM vehicle security systems typically use the black oval dot embedded in the shank of the ignition key to verify that an honest key is being used rather than a lock breaker or a pick. They rely on making good electrical connections to the metal strips on each side of the dot. Skin oil on the contacts can rub off onto the contacts in the lock and eventually build up to the point that the system cannot accurately read the key.
The fix is to clean the key with rubbing alcohol, and clean the lock contacts also. To clean the lock, cut a paperboard (e. g., from a dry cereal box) strip the same width of the key at the shank, as long as the shank plus enough extra to use as a handle. Cut a strip of fabric or a strong paper towel to the same width and twice the length of the paperboard strip. Dampen the middle of this second strip with rubbing alcohol, wrap it around one end of the paperboard strip, then slide this into the lock (as far in as the black dot on the key goes) and work it back and forth several times to wipe off the lock contacts. This should take care of the problem if it is dirty contacts.
If you have a lot of stuff attached to the ring on your car keys, the weight swinging back and forth may have caused excess wear on the lock and damaged it. This is behind the recent recalls; many GM locks are not sturdy enough for that kind of abuse, and some have failed while the vehicle was being driven, leading to unexpected engine shutdown and possible accidents. The security section of the lock may be affected by this problem. Check whether your vehicle is affected by the ignition lock recall, and be sure to mention your security system problem to the dealer if it is.
As a last resort, I have developed a relatively simple means to bypass the system, but I'm reluctant to share it in a public forum because I don't want to let potential thieves know how it's done. If you still need this information after trying the steps above, post a comment on your results and I'll send the method to you by e-mail.
