So you have a bad voltage regulator, want a medal? I've installed an upgraded car stereo in every car that I've owned before the Evo, including the BMW. Every single one of them was 13.8v.

There are lots of things about cars that I don't know shit about but I'm pretty good with stereos and wiring.

Either way, you will end up with some baller wiring. A new alt should produce anywhere from 13.7 to 14.7v (I test on average 2 a day) but it wont matter how much it is putting out if it's not getting to the pump. I see the thought.

Alright bro, I'll take your word for it. I've owned six cars and they were all different brands, every one of them read 13.8 and I've obviously owned quite a few multimeters over the years. Maybe it depends on where you measure it from.

I'd urinate on my trunk if I thought it'd fix my fueling problem.

Just testing theories here guys. At this point most everything else has been tried with no success. And a few things he mentioned led me to think that getting power closer to the Alt may be worth a shot. That and I'm not sold on the grounds being used, but we'll see how this all goes then go from there.

BTW, he mentioned late in our conversation that Buschur instructs to get power from the engine bay for his fuel pump install, coincidence? Maybe not.

If this doesn't work, then it's time to borrow a Bosch 044 from someone local to test. If nobody else has one freely available, I'll take mine out of my gsx and let him borrow it.

One thing at a time..

I'm going to give another +1 to the 13.8 to 14.7 range being fine. I test a few per week, and our test bench passes everything inside that range.

I can also confirm that issue, as I had fuel issues on the dyno this last session, before rewiring my pumps to get power straight from the battery in the trunk. What is Gate's doing? Who else is at these power levels?

Talk to teheodi on here..he's got a bosch 044, unless it was stolen from someone else.

Jesus Lomker, cool your ego when someone mentions something different then your opinion. You say it like it's fact, but it's not. Just try your theory, it seems very unlikely considerig how the BAP made it act before. Re-do your ground just to be sure to begin with.

A lot of these people have done plenty of work with batteries I'm sure. You've owned 6 cars, in the famous words of yourself, want a medal? I worked on everything that has to do with voltage in a car for most of my working life, about 5 years combined. And I would say I see most cars average 13.5-14.2 like it's nothing. Maybe get a more sensitive multimeter?

Wiring isn't glamorous enough to discussed in magazines so I have no idea what Gates does.

You have your pumps right on the battery in the trunk? That's what I have now. What was your setup before?

Like speedfreak mentioned, Buschur has people tap up in the engine bay for his double-pump kit. BlaqOPs doesn't really offer advice but I tapped the positive feed to the fuse box under the dash when I put that in.

The ground I am currently using for the Bosch is about an inch from the battery's ground.

I get sick of typing all this crap since it's almost too much to say, much less type. Suffice to say the pump works 'better' off of the positive feed from the engine bay (the car's relay) than it does from the battery, which is a part of the thinking with running a new positive from the engine bay power terminals (closer to the alternator).

Yeah, sorry guys. I'm burned out on this.

[Kracka]

Good luck...I'd love to see one of these fixes you're trying solve the problem!

[turbotalon1g]

x2 with 311, I was providing more info incase you were worried about any fluctuation.

I was not aware I was dealing with an electronics expert.

Yeah, I believe that.

[mlomker]

Given my budget, I decided to try putting in some wiring that I had on hand. I ran an 8ga wire from the engine bay and a different ground for the Bosch. I'll test that out tomorrow. It started and ran, anyway.

I plan to order a proper 4ga setup but that'll take another week since I need to drill the firewall and will have to go to Dad's for that. I should buy a battery-powered drill one of these days.

[badinblack]

I feel the end is nearing, there isn't much left. good luck agin man.

Thanks man. I ordered the 4ga wiring kit today and I'm sure I'll find an opportunity on the cruise to do a pull and test the current configuration.

I gained 1-2psi at idle just from the wiring change and that's probably a good sign.

[mlomker]

The 8ga from the engine bay didn't change anything so I assume a 4ga wouldn't either.

I have one of those Jay Racing 044's on the way--should arrive Wed. I'll still do power distribution blocks in the trunk (that should arrive Tues) since I don't like how messy it looks right now.

[turbotalon1g]

power distribution blocks are awesome, i love mine.

[mlomker]

Here's the Jay Racing 044. The brand-name on it is Protec. They bench test every pump prior to shipment so swapping this in tonight should answer that question.

[TheBlizzard]

Good luck man, if it doesn't work burn it.
