I changed my water pump on my truck and pretty sure I now have timing issues after changing it. The truck idled fine before working on it, and seemed to have more power; now it idles roughly. It was stalling on its own (after changing the pump), but then I turned the distributor some and it would no longer die (but still idle rough). When I put the belt back on I didnt crank it over a couple times, so one of the cams may be of a tooth or so? I'm going to tear it apart and check the top dead center marks after a couple of cranks. After I check that what else should I do, anything with the distributor? What degrees should the timing be at after all is done and checked with the timing light? If any body has a timing guide from scratch on this engine that would help also! Any other suggestions? Thanks in advance.

There's a good change you're a tooth off on the belt... I did one 3.0 timing belt and their marks you have to line up to suck. Pull it apart and see what's up. Do some searching here, there has to be a V6 timing belt thread....

How should the distributor be adjusted before I check the timing? What degree should I be at when checking the timing with the light after all is put back together? I've searched up and down for this info on the forum, and can't seem to find it. Thanks for the welcome also, I've been lurking for a while.
I only have the crummy books, none of them had anything reguarding timing specifications. The under hood sticker may have it somewhere. There are two pins on the diagnosis plug that should be jumped before timing (TE1 & E1 I think) for things to work right. Other things can make the idle funny. I had a combination of air leaks and poor mounting of the airflow sensor. The trap door on the airflow sensor is almost completely closed at idle. If the bushings (or brackets) are crummy or missing the engine vibrations shake the trap door shut intermittently.

My theory on distributor placement (When you have pulled it out...) Is to find the #1 spark plug plug on the dist. cap, follow it's path to the electrode inside. (Sometimes where the plug is and where the corisponding electrod is are not right under each other...) Set the truck to TDC on the number 1 cylinder on the compression stroke, then do the guess and check method, slide the ditributor in, and see where the rotor is pointing, look in the cap and see if it looks right... if not, try a tooth one way or the other. Once you have it in on the right tooth, put it all together and fire it up and adjust timing.
