I have a 2001 chevy s10 and it was running good. Then all of sudden it died out.I found out that one of ecm fuses (20amp) keeps blowing out as soon as I turn the key towards on. Is there any way you could guide me in the right way towards fixing my problem.

Hello,

This is likely due to a short in the wiring. Check the wire for short to ground. Look for any melted part or exposes insulation.

Here is a helpful guide on how to check wiring:

I have attached the wiring schematics for your reference.

Please let me know of any questions.
Thank you.
