fuel pump error Help

Riceball777 · 04-29-2016, 08:01 PM

So i install the fuel it stage 2 fuel pump about a month ago with the aftermarket fuel line and ethanol sensor and the car runs great. The low pressure fuel pump never drops pressure at all and the high pres sour is always over 1000 psi when the car is at WOT. Before with e30 in the tank the low pressure would dip in the low 40's but not any more with the new walbro pump.

But about once a week i get this fuel pump error on the screen. The error is only there for about 30 seconds and it will be gone. This only happens once a week or so and the car drives fine. When I log the fuel pressure seems to be fine. Whats up?

It's completely normal. Almost all of us with iDrive have it. If you look up my old threads I went into detail talking with Wedge about it. Also I talked to Steve @ Fuel it about it too...

If you log your fuel pressure it will be perfect. Only theory I have left is that the 450 is overdriving the stock regulator

We get it to with the Walbro 450 installed in the tank. Nothing to worry about I'm told.
