Got a chase bays harness ages ago. Just now getting around to using it. I’ve heard nightmares about their wiring harnesses and people having lots of issues. Probably why they don’t make them anymore. 91 si crx. OBD1 tucked harness. Turn the key on but the fuel pump doesn’t come on. Motor turns over but I’m not getting fuel. I’ve got the wires hooked up per the instructions. Anyone have a similar experience and find a fix?

 

I'd go ahead pull the rear seat/carpet whatever and put 12v to the pump and see if it works to rule out a bad pump, then check the circuitry from there, main relay, fuses, etc.

If you end up having a bad engine harness, then I've had really good luck with an eBay harness... I think the seller/manufacturer was Motortech or something like that. I'd have to check the tag in my engine bay. It's not a tucked harness, more like the OE style, but it's thinner and easier to work with for sure. But i'm not sure if the engine harness would cause problems with your fuel pump.

 

^^^ Mono Tech if I'm not mistaken

 

That’s pretty much what my plan was. It’s a new fuel pump but guess it wouldn’t hurt to check though. Thanks for the input.
