Where is the ecm on 89 chevy s10

Truck still won't start It is getting plenty of fuel

Here is a list of things we have replaced on the truck

1 starter
2 alternator
3 distributor
4 fuel pressure regulator
5 halls effect switch
6 fuel injector
7 spark plugs
8 spark plug wires
9 fuel pump
10 battery
Now we are looking for the engine control module does anyone know where it is located.

The truck is an 89 chevy s10 2.5L 4 cyl.

I believe the ECM lives up behind the glove box: you remove the glove box and the ECM should be right there.

Need more info. What engine. Why all the parts?

Check inside your distributor there is a little chip that has a couple wires going into it.. mine got wet and rusted out. 20 bucks later and the truck was running. I did the same thing you did sorta replaced the wires plugs, coil and then took it out and replaced it..
