I’ve gotta 93,4.0 anyway, the fuel pumps not running long enough, just runs for like half a second. Also, it you cycle the key, the fuel pump turns on twice and that’s all.
wait a couple seconds and try it again then it runs but only twice again. I even let pressure off the fuel rail and no difference

I’ve literally checked everything I could think. I’ve checked relays. Switched out relays, checked fuses. Checked Power at the pump.

Could this be a security issue

I have the yellow and purple wire grounded out inside the drivers door and passager side door.

Is it possible that the security system is still on.

but the lights aren’t flashing, and there’s no security light on or anything.

Also the fuel pumps new.
