Well i got it to start up it to a few times turning the switch on and off for the fuel pressure to raise up past 50 which will allow it to start. i gently rev'd the engine a little, left it alone to idle then the fuel pressure dropped, engine shut off and now there is now fuel pressure or fuel pump action at all. i tested the voltage going in to the pump and it hit 12 volts for the 2 seconds after ignition turn on and off. SO I Figure it is likely the fuel pump. I probably didn't need to replace the regulator but i did clean out the fuel system and throttle body and intake mani while I had it taken apart. And the cleaning was badly needed. time to get a good quality fuel pump now. I have a 1 year warranty on the pump i bought on ebay, it may cost me shipping to get it replaced through there. A friend's wife has a 98 s10 and had to replace her pump 7 times in a 4 yr period. If i can get a good discount I may just buy one from a local store.

 

Do yourself a favor and do not follow in the footsteps of your friend's wife. Get an AC Delco pump. No substitutes.

 

As far as the spark plug goes listen to swartlkk simple swivel extension will get her out with a little trouble but not much leave that rod alone
