Inside the truck just under the dash

What is your question?

I have a 1991 S10 trying to install a switch commatateur interrupter. Also if you have a diagram that's where it is and how to install it.car turns over very easily but will not fire or start I check all fuses that I could find Thank you Best Regards

What makes this problem better or worse?

it wouldn't start hot and it won't start cold

How long has your 1991 Chevrolet S10 had this problem?

I was driving it and it just quit running and wouldn't start again to have it towed home
