Fitech fuel pump problems. Just make sure it maintains pressure. I would suggest you get a fuel pressure gauge. If power in orange wire during prime it is not the unit. Test the fuel pump fuse for power when priming. A standard mechanical fuel pump can. It is something to do with the pump or ground for the pump.
I will be filling a. You set your prime to a longer period of time. One common problem that many car builders have when installing efi is getting the fuel pump to provide a constant supply of high pressure fuel to the injectors. Fuel pumps etc spent hours with tech support and nothing. Fitech fuel injection new auto parts. Hopefully your installer used the fitech orange wire to go directly to the pump without a relay.
If pump is really loud it is most likely working too hard. If so you can use pwm to slow the pump and reduce the noise. Replaced the in tank with a fitech pump and put in a fuel pressure gauge near the throttle body. Still having a lot of problems running lean and backfiring when rpms get over 3000. Carry a test light. Then the handheld seemed to fail.
I have mine set to 20 seconds some times. Well i finally got a hold of fitech. After leaving message after message to 3 different techs facebook messages facebook page posts and emails i finally got a hold of a human being.
