I'm dealing with an issue on my 2003 BA turbo manual where the fuel pump relay is not getting a trigger signal from the PCM. The car is tuned with an SCT flash tuner, but this was done years ago, this issue is only recent. The fuel pump does not get a signal from the PCM to prime or run. Sometimes disconnecting the battery and letting the PCM reset will fix it, sometimes it won't, but eventually it stops working and won't work again until reset. The fuel pump and all its wiring after the fuse box is fine, the car runs without issue if I bridge out the fuel pump relay with a jumper wire. I have swapped and tested multiple relays and changed the inertia switch, didn't fix it. The wires between the PCM and the fuel pump relay are fine (<1ohm), and all the PCM pins and connectors look fine, so I'm convinced the PCM isn't opening the ground signal to open the fuel pump relay (it does have 12v on the coil side). When it happens it throws code P0230 fuel pump relay primary circuit malfinction. Has anyone encountered this before and has any idea where to look next? Is my PCM dead? Any advice is appreciated, thanks

I have a GU Patrol with a Barra Turbo swap. Its FG gas bottom and BF head. Got a few things done making 400rwhp running about 20psi. My issue is that when you realy put the boot into it in 2nd gear at around 3500-4000 it looses all power instantly, if you let off it kicks back in. Its backfires and makes some horrible noises when it happens. Only happens in 2nd. Already replaced plugs and coilpacks. It has to be either fuel or boost cut just dont know why its happening or how to stop it. Cheers for any help.

Ok I’ve read page after page after page.... heres where it starts.... bought a ba xr6 turbo Automatic and it came with a x3 flash device that has custom tunes, base 4-5 psi - 8psi - 10psi. Car drives great no weird noises or anything of the like. The problem I’m having is to do with a overboost/limiter issue. This is the 10psi tune. Car accelerates great but once it hits the 10psi mark it either goes to 12psi or it hits 9-10 and it’s like a rev limit and the exhaust makes an almost ‘flame’ sound? And the boost gauge flickers up and down 1psi. Mostly this happens with WOT. Especially does it when just in Drive and going WOT, not so bad in sport mode because I can shift before it gets to the almost misfire stage and goes weird. Most times regardless of in drive or sports mode it’s around 4000rpm. Sometimes though in drive and sports mode it will rev out and hit boost perfectly and have no issues but it’s very short lived and then it’s back to ‘missing’ 2 minutes later. Now when I put it back to stock it hits 5 psi steady as can be at WOT but as it hits 5000-5500rpm it makes the same weird flame limiter noise. Heres what I’ve tried. •New plugs gapped to 7.5 •New boost control solenoid •Clean throttle body •Tighten all hoses that I can access •Run turbo hose straight to wastegate (hits 5-6psi and goes great •Disconnect battery for 10 minutes and then drive WOT New coil packs will be here by the end of the week as there about the last thing I can think of that I can do myself, there still originals and car has done 170,000ks. So if anyone can help me that would be AWESOME! I’ve read so many threads that seem to be my problem and they either never come back with the solution or I’ve tried what they’ve done to no avail.
