I run a fuel boss only setup, no check engine light but I get a P0130 (and its 1693 companion) code if I go looking. I need to get a smog check this week so I'm preparing for that.  Is there anything I can jump, remove, connect that will make the computer think a electric pump is present? 

 

Otherwise ill strap the old junk electric pump back in there and plug it in just long enough to get smog don't. .

or even just a resistor

I think you're on the right track there

Did me resetting with my scan tool un set the monitors? 

Anytime a code is set, a code is cleared with a scan tool or the batteries are disconnected the monitors will need to reset.

So on this. what wire from the ECM? 15 or 35? I saw your drawing on the other page, but it looks like both 15 and 35 run to 86 and 85 on the relay

The two wires are joined together in the wire harness at S160 (splice) and go to the lift pump.  You could add a resister between the power led and ground to mimic the fuel pump.

Simple enough. Any size in particular? That won’t damage the ECU will it? If I could get the code to clear tonight, I should have the monitors reset for an inspection next week.

 

honstly that’s assuming this fuel pump code is even a problem. Monitors are likely reset because I cleared the code recently to see if it comes back. If the monitors clear without mimicing tue electric pump I’m golden. 

@IBMobile thanks for the tip on the relay is worked beautifully. I used the plug from my fuel boss Hobbs switch I was no longer using to make a clean “fooler”. I just think I’ll measure the resistance in the relay sometime and make a less bulky plug. I think Rich from GDP should have this as an option for his fuel boss kit. 

 

Once plugged in in the code and monitors reset Immediately on their own, looks like I’m ready for my smog check.

Boom! Ca smog passed. He skipped right over the BHAF, likely because it’s attached to a k&n tube.

 

That's great to hear.   I like the relay set up, that's what I have but in the PDC.  The power draw between pins 86 and 85 of that type of relay is .15-.18 amps with a resistance of ~80Ω.  So it doesn't take much to fool the EMC and turn of the light.
