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

Perform the tests in the link below:

Thanks... could u tell me where the map sensor is located?

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:
