I did that. Ran a ridiculous size wire straight from the battery to the pump (guage 4), just to see if that was my problem. Fixed it for a couple of hours. But it came back.

Hey bo. Yes the fuel pump came with a filter. And the other two are kinda like a "just in case" thing. .... ....

Checked the fuel filters and all lines under the car to make sure nothing is bent or kinked tonight (even started the car and woke up the neighbor hood for sure, its 3am btw). Didn't find anything. Filters were nice and clean too. Right now im REALLY thinking its the pump itself. Leaning toward a racetronix unit. http://www.lingenfelter.com/store/rx-f-fpk.html

Well so much for that. The straight battery thing worked for a while. But now its back and worse. Fuel pressure was at 20 and the car turns off. I think this fuel pump is a piece of ♥♥♥♥. Im going to make sure theres no restriction in the lines tonight though. SIDE NOTE: Heres how my fuel system is hooked up. Maybe something is wrong. Tank(fuel pump inside)-->line---->fuel filter one----->hard line----->fuel filter two------>right fuel rail----->line----->left fuel rail------>regulator in----->return out---->line back to tank Seems right to me and its worked for a few mouthes now but im stumped so im starting for square one.

gnose?

Well i had to find out if the voltage was a problem before i spend more money. So i ran a wire straight from the battery to a switch in the cockpit to the pump. Now everything is fine. The fuel is fully adjustable and everything works as suppose too. So that confirms the electrical issue. Could it be the relay?

Thanks Bart. So you think that kit might help?

11.5 is apparently to low according to some research. could this help? http://www.fullthrottlespeed.com/itemdesc.asp?CartId={AC359D11-A679-4B32-B26F-CC7EA836AF96EVEREST}&ic=717LS1HOTWIRE&eq=717LS1HOTWIRE%2D1&Tp=

Voltage at pump is 11.56 Both the pump and the reglator were bought from summit. So im pretty sure they are the real deal.

No suggestions? anything? Ill even take stupid guesses at this point.

Im using a reworked camaro harness. The pcm controls the fuel pump.

Hey guys. Theres a recent issue with the ls z car. About 2 months ago the stock fuel pump died on me (using an ls1 gas tank with the stock fuel pump at the time by the way). So i changed it out to this unit (http://store.summitracing.com/partdetail.asp?autofilter=1&part=GRN%2DGM722%2D2&N=700+4294836951+4294908216+4294908198+115&autoview=sku). The car ran great for about a month. Now theres another fuel issue popping up that I cant figure out. Theres a ridiculous wining noise that started just recently to come from the pump now (you know that sound when the fuel pump sounds like its dying?). I took the pump out to see whats wrong. Everything seems fine. Put it back in and it starts to make the noise within 5 mins of idling. I was looking at the fuel pressure at the regulator. It reads 45ish which is horrible (suppose to be 58 range). So i try to adjust the regulator and it wont go above 48psi. When i do try to go past 48 the needle on the regulator pressure just moves back and forth in the 48 range (45-48-45-etc). The pump is brand new, and was fine so i don't think its that (plus i threw away the box because im an idiot). Ive also checked around on ls1tech and sometimes if the battery is low for some reason the symptoms i decribed are present. I checked my battery and it was fine though. Could a clogged fuel filter do this (only have about 2k on the whole swap and with those filters)? What else should i check? Sorry its so damn long.

Btw I'm not the seller. Just though it was interesting and should be discussed.

Guess i got lucky. I didn't buy a motor from them though. Just adjustable shocks.

Speaking of "minimalistic" engine bays. I was thinking of relocating somethings in the 78 engine bay. One Of these things was the carbon canister (behind one of the front wheels is what i was thinking). I know Cali has a visual inspection. Anyone know if its ok to move that stupid thing? Its not like im removing it. It will still be hooked up, just not out in the open.

Do we have 10% mix in cali? I didnt notice if we did. I usally have no choice anyway. When i need to fill up i need to fill up. Always put in 91 octane in all my cars anyway.

Depending on the price, I might want one for an l28 as well.

And it will be for a while....

Thank you. You should see the idea i got in mind for my 78.

i will also be waiting for that write up.

Man. I want that car. I love how the tail lights look and the car blinks. Amazing.

Thats awesome.

Due to the response I guess no one has broke them........
