i have a 09 race gas push turbo. the sled will fire but the fuel pressure bounces from about 2-12psi for a few seconds then the sled shuts off. if i hook a small battery to the pump, the pressure goes right up to 38ish psi and the sled starts fine and runs good in the garage. my fuel pump is getting 16.4 which seems awfully high to me. the stator all checked out good with ohms and volts but i changed it anyhow to one i know is good. it still does the same thing. also i'm getting 19.2 volts off my charging coil(yellow to brown) when running. which is in specs but my headlights and accasory plugs are not getting any power.i though maybe it was the ccu, i put it on another sled and everything works fine. are the fuel pump circuit and headlights some how connected through the ecu??? or do i have a bad harness that doesnt actually look bad....i need help!!!!
electrical problem, please help!!!! confused and frusterated

another question.....does the ccu supply power to the ecu??
do you have anything hooked to your fuel pumps dc circuit? If you have gauges etc hooked to the same circuit you are more than likely pulling too much amperage away from your fuel pump and it cannot work properly!
i don't believe there is anything else wired to the fuel pump circuit. i do have a few extra guages but only the air/fuel ratio gauge has power going to it. i have headlight deletes so i have that gauge and a small light on the hood(with a h3 bulb) hooked into my high beams(which are getting no power right now). the push box is wired into the accessory plug, which isn't getting any power right now either.

That circuit will supply enough current (amperage) until the fuse blows. Everything on that circuit will work fine until then.
there's a fuse on the fuel pump circuit? where would i find that. i've had this sled torn down to about nothing and never saw any fuse.....
