ecm problem?

[southernblazer]

I have a 94 chevy blazer (full size k1500 5.7Lengine). I think I may have fried my ecm while installing a blower motor. When you turn the key the service engine light doesnt come on, and it just turns over, wont start.

any way to tell if ecm is working properly?

Thanks.

OBD1, that's the initial check, see if the light comes on.

Could be the bulb burned out (wouldn't that be nice) but if it won't start...

Did you check the fuses?

yeah, checked all fuses, I'm going to check the fuel pump fuse & relay, and the injectors next.
