2000 Chevy S10 won't start when its cold and
occasionally when it's a little warmer. I have
changed the spider injector, fuel regulator, fuel
pump 3x's, fuel filter twice, coil pk, distributor cap,
rotar and crank positioning sensor. My mechanic
is stumped and I'm broke. I have no idea what to
do to fix this, please help

May be the Ignition Control Module in the distributor, they can be checked. And no mention of the plugs and wires, what shape would those be in?
We changed the ignition control module I think and we did do a complete tune up. Another mechanic said it had to do with the ignition key to start the truck. When he wiggles the key the security light goes out and it starts easier if it's warm but if it's cold, still having problems. Thank u for ur help
Then that sounds about right.

Check oil pressure when you're trying to start. Fuel pump runs for 2 seconds when the key is put in the run position. Then the fuel pumps power is routed through the oil pressure sensor until it receives a pulse signal from the distributor. Low oil pressure would prevent the circuit from changing over.
I have a 99 s10 it will not start when it is cold. However it will start if it is above 35 out side. I put in a new battery and a new fuel pump. It still will not start when it is cold out. I am lost on what to do
