Hi,

I am reaching the end of a turbo build on my jap import 1.8L 1996 Eunos Roadster using the ME442.

The car will only run with FP connected to GND in the diagnostic box, bypassing the fuel pump relay.

I have tried setting the HB OUT + pin to Fuel pump in MEITE as suggested online. However, this has not resolved the problem.

The fuel pump does not prime when the ignition is switched on.

Any suggestions would be massively appreciated.

I have the same issue, had you got anywhere with this?

Hi,

Yes I got it sorted by setting each pin to the fuel pump and listening for the fuel pump priming. From memory I set the fuel pump to LS13 or LS19. I'll have a look in MEITE tonight and tell you which pin worked for me.

I have the same issue on my 1991 NA after installing an me442 and setting the hb out +, when I bridge the FP and gnd pins the FP primes and the car starts. I tried setting LS1 to LS18 to fuel pump one at a time but none have worked.

I got on the ME and the solution they gave is to wire the FP pin in the diagnostics port to the T2 pin of the ECU connector. They confirmed I can instead wire the FP pin to one of the LS pins on the Aux connector which will be easier as I have a plug I can plug into it.

I am not sure the best way to wire something permanently into the diagnostics port. Maybe into the back of it, I'm guessing there is a good way to do it that cannot come loose while driving?
