This car had twin DW300’s. They were a couple years old and could’ve used some heavier gauge wiring. Filters were looking sketchy too. The ECUGN was watching and protecting! Low fuel pressure fault code was activating frequently. Turbo is a 6466 on a healthy 109 pushing 800 flywheel. She’s...

This however.... well this definitely will not do..... (this was before installation of the twin hellcat pumps) This was activating the fuel pressure safety system.

That'll do pig.... that'll do.... SMP 160Lb injectors, twin hellcat pumps, -10 feed and -6 return. twin 10 gauge power feeds to alternator with twin 10 gauge grounds to the battery.

The Buick power source book (aka "how to hotrod your buick v6") has build sheets for many different V6 applications. That's my go-to source when I have questions like this. It can be downloaded as a pdf file from somewhere, break out the google. Or hit ebay for a copy.

An air/fuel ratio problem doesn’t necessarily indicate a fuel pressure problem. There’s lots of different reasons for being rich or lean. A stock ecm with a powerlogger can accept a fuel pressure sensor which you can look at. An aftermarket ECU like ECUGN can accept a fuel pressure sensor and...

Beef that stuff up with some new wiring. If you need to swap polarity it's no big deal. Just de-pin it and swap. https://www.racetronix.biz/p/blt1-fuel-pump-wiring-harness-hd/fpwh-018 https://www.racetronix.biz/p/blt1-bulkhead-wiring-assembly-hd-tyco/bcwa-blt1 fpwh-018 has a grounding ring...

Spring is here! Getting the wagon out of storage this weekend. Plans include an ignition upgrade to a Cruz 12-1 trigger and a fresh fuel filter.

New switch too. Might want to put new seals inside too. If it's leaking down internally, you'll be able to tell if it cycles the pump while it's just sitting there doing nothing (key on ofcourse)

I'd be interested in the re-wound motor rotors but that's probably about it. That's what caught my attention. I rebuild quite a few powermasters locally, I always use seal kits from Pete Hoffman / Richard Clark. Along with new delco switches and hydac accumulators from where ever. I have an...

Nope. Just came across it recently when looking. My buddy just called them, no answer......

I think it’s the same car. Can’t be many like it lol.

Not positive but looks like my buddy ended up with that car? Or a really similar one

installed one last summer in our station wagon. Works nicely and it dropped right in.

Which ECU are you using?

Check for 12V power at the ignition module, and check out this little video.
