1993 s10 2.5L the aldl not responding and code reader says module not responding
Now you need a wiring diagram & work your way back on all
of the ALDL Pins or wires, to see if their good end to end
Then you need to see what data some of them are supposed
to have at the connector.
21 years -- most likely some corrosion in the wiring, where somewhat exposed to the road,engine bay, etc
The ses light,idle,& such are another issue to work on.
I think the codes, if any, are less help than component testing
the vehicle sensors & wiring
The OBD1 Systems had common sensor wiring or grounds shared,
so grounds & failed sensors can effect other sensors & send
you all sorts of places, rather than walking down every wire with
a wiring diagram to see what's what

1993 s10 transmission slips. Need to know what to
Get it up in the air - pull the driveshaft, the linkage and any sensor wiring, pull, drain and cap the cooling fluid lines and then just start unbolting everything around the bell-housing. I forget if mine had a cross member stabilizer bar bolted from side to side of the chasse? but obviously that will have to come off also.
Afterthought: If it's not slipping that badly and you don't feel like tackling this big job right away. Drain the fluid and replace it with (I can't think of the name) but they make a fluid to help stop slipping tranny's. I'm sure you can get it at Advanced auto. If you have never changed a tranny, even if you are good with your hands turning a wrench - and you are outside without a lift and working off jack stands (DON'T DO IT!!!) Also, if you are alone? You will need a floor jack when it comes time to slide the tranny back and drop her down. Do you plan on fixing the tranny yourself? or going to a junk yard? Junkyards will guaranty there products, but they don't guaranty the one your getting doesn't have issues, because they don't know. they just pull them label them and wait to sell them to a guy like us. What if you spend the whole weekend pulling and installing the new/used one and it too slips. There goes next weekend back under the vehicle while the wife/girlfriend stares at you from the window yelling things like: "You almost done? I want to go to the Mall! Or worst of all!!! Then her mother comes over and they both stare at you from the window. maybe she brings her husband who leans over and talks to you from the engine compartment with his own tranny war-stories. As you can tell I'm thinking back at my own nightmares. But, I'm fifty-one now and all three of those people are now dead. Today when I have car issues I use the money from their life insurance to pay for them... So don't despair it all works out in the end.
