I recently acquired an 88 CRX w/ a 95 D16z6 motor.

Fuel pump is not getting a signal from the main relay.

ECU from 95 civic si was recently fixed by Neal Sutton here in tampa...ecu was from auto...was switched to 5spd.

Main relay is clicking, sometimes car starts, other times it doesn't start. We've tried several main relays, will be pulling a main relay from another crx we have to verify that its not a dysfunctional main relay...although we've tried several that we pulled from a junkyard and all seem to be acting similiarly.

Any suggestions would be great.

Thanks.

 

This might help you in finding out if you have some sort of electrical/ground issue. Hope this helps eliminate the main relay as being the issue.

By the way, all your grounds for your fuel pump are by the passenger side taillights. ~9 grounds there for the fuel pump as well as all your taillights.

 

thanks

 

ECU is the problem, jumped ground and the fuel pump primed.

Now I need to get the ecu fixed.
