Like the heading says after the engine was swapped out with another 4.3 engine the light has been on ever since. Took it to a chev dealer and said they could not time it because it was to far out of time. They call chev support and they were told to pull the distributor and turn 1 tooth. They pulled the distributor, noticed that my gear on distributor was worn, scoped the cam gear said it was worn also. They told me I need a new cam gear and they would sell me one and installl it for the low,low price of $2600. They never even tried what chev support suggested. Turning it one tooth. I suggested maybe just changing the distributor gear and they said it would not help. Seems to me like they are trying to Bend me over and drive me! Everywhere I read in various forms say that the distributor was installed wrong. Can anybody verify this? I'm now going to another Garage on Monday and am changing out the distributor gear. If this does not get the light off I'm going to turn distributor 1 tooth. This engine has about 100,000kms on it. It is sluggish and misses a little when cold, but when warms up runs fine. Do I advance it or retard it? Clockwise 1 tooth or counterclockwise 1 tooth?

first of all, turning the distributor (1) tooth really isn't going to do much to solve this-unless the distributor is already turned all the way in one dirrection or the other.if u set the timing when u did the swap, there should be no isssues with how the truck runs. question, did u change the cap/rotor/plugs/wires/etc. with the swap they could cause some hesitation with a cold engine. 100,00K is not that much to worry about.i recently swapped an enginge from a '94 Astro, (that i had removed from an '86 Astro, and installed in the '94) and put it into my '94 Jimmy. it has been runnin' for about 6 weeks, no problems at all so far. the engine's milage i feel is preety accurate (i bought the '86 from the origional owner, my neighbour, and installed it in my dad's '94) and it currently sits @ just over 379,000K. doesn't burn any oil, still has plenty of power, and no hesitation. clear the code, check everything i mentioned above and see where it leaves u with cold running. what is the code p1345 for any ways?

P1345 = Cam to Crankshaft Position Correction fault

Everywhere I read says the distributor is put in wrong. The engine was changed at a Gm dealer. I just got the blazer and am trying to get the light off. I'm going to change the Gear on the distributor( as it was worn) and see if this other mechanic can put it in correctly. P1345 code can be erased and then comes back on immediatley. The code is the correlation between cam and crank position. Really my problem is not related to the one you explained. Thanks anyway.

I would say move it over one tooth. You could do it yourself cause it's really not that hard to do.
Also make the sure the cap, rotor and the distributor itself is tight.
