I have a 1993 Camaro Z-28, and I was running it a few days ago and the motor stop functioning when I was running. I was thinking it could be the coil or the fuel pump. There's any way to verify the car with the OBDI with out the scanner, or anyone could help me with this???? Thanks a lot

 

First thing you need to do is test if it is getting spark at the coil and at the plugs, then what the fuel pressure is.

Do a search for pulling codes on OBDI, you can do it with out a scanner.

 

I use a digital meter but I don't know how to get the codes.

 

Since you have a 93, you can flash the codes on the SES light, by shorting the pins in the ALDL connector. Shoebox has a guide:
