o.k., so i finally got rid of my 99' and am ready to "refresh" the old 94' and add a few new parts. My questions....
1. can i put a obd 2 pcm out of a 96' or newer tk in place of my stock pcm?
2. what are the needed changes to do so?
3. Will my obd 2 style port be useable with an obd 2 code reader if the pcm is changed?
4. It is a 5 speed, 4 wheel drive...what pcm codes will work?
5. i also have a fuel leak somewhere in the engine valley...bad enough to cover the clutch and make it slip occasionally...any ideas? (i just replaced the hpop and lines a few months back)
6. one final thing...i kept my super chips programmer out of the 99'...will it work in the 94' if i change pcm's and how much difference can i expect as compared to the 99'

Use a PCM out of a 96 or newer 5-speed truck. You'll be good to go.

If it's a 1700 or 1705 programmer, then it will work just fine with your truck.

well...i ordered a 96' ecm this a.m....should be here tomorrow! Now i can get that superchips up and running.

now, i have encountered a brand new set of troubles...when i crank the tk after it sits over night, it runs a few seconds and then dies. When you try to start it up again you have to spin it for a while (10 or 15 seconds). I think i may have a fuel drain back issue. Any body else ran into this before? Funny thing is...it doesn't always do it.
