I have a 1995 honda civic dx. It won't start. I checked the main relay and there seems to be no current to the gas pump but the main relay works because I tried on another honda and it worked. Could anyone help me please

Along the firewall, just to the right of the fuel filter. If the CEL comes on and goes off after 2 seconds, when the ignition switch is turned to ON (Position II), the ECM is likely fine.

The light stays on.. do u think it could be the ecm?. could it be the ignition?

Yes, it could be ECM failure, but run these tests first:

. Test all under dash and under hood fuses with a test light or multimeter:

Be very thorough, since it will save a lot of time and money. Pay particular attention to the ACG (ALT) (S) fuse, located in the under dash fuse box.

. Perform the K-Test on the ECM.

If the CEL still stays on, check the ignition switch for wear, pitting, or melting:
