Fuel pump driver module symptoms6/20/2023 I replaced my AVO pump with an Aeromotive pump and it did not fix the problems discussed in this thread. Not sure if you have read the whole thread or not but really the pump is not the issue its the voltage getting to the pump. The problem with the legacy, near as we can tell, is you never get above 11.7 volts out of the fuel pump control module, even if a wire is direct to the module from the battery. Im sure everyones aftermarket pump, whether it be, Aeromotive, Walbro, AVO etc all are tested at battery + alt voltage which is generally 13.5 volts and above. Im not really sure why the discussion on the pump. but this is the interesting bit for other owners (and later gen cars!!) was on reading up i found this on the internet. The solution should be fairly straightforward (by replacing the module and maybe the pump). Martin put me on to it when i described what was going on and said that the module was buried deep in the rear passenger side boot area. I can get the car running by uplugging the pump and 'resetting' the control module.so problems somewhere Lots of checking later and it appeared to have a fueling om the fuel pump control module. Ive put a replacement lump in it and had problems starting it. the engine had melted a piston (cause unknown). Been looking into an issue ive had with the bh and thought i would post this up as it could effect other later cars.
