11 volts ? thats literally a dead battery. Im sure the car battery should stay b/w 12.5 and 13.8 . Im not planning any stereo for this car, Really been there did that, considered it again , and frankly dont need the pain of frustration 
So to answer buddy will the Gen 3 fuel pump be ok ? |
I have seen as low as 9.3 volts go to the fuel pump on a variety of cars, heavily modded ones, near OEM etc. Anywhere from idle to WOT. Could have been ground leaks in some, others its the other equipment that saps the volts, sometimes its the wiring to the pump just being too thin.
Running your own wires direct from the battery on it's own relay(s) etc will do quite a bit for you....I would just for curiosity's sake check what volts run to the fuel pump on MR2's, I have never had the chance to check those yet....ACC on and have your volt meter plugged into the terminal where the pump connects. If you have peak/hold functions on your voltmeter, then give those a go and see what the range is during just startup, idle after warm up, idle after a good run, perhaps if you can have a buddy check the volts while going full-boogey, LOL.
that tank is located in a messed up place btw
