There seems to be no end to the problems.

After replacing the opti, coil, alternator, battery wires, ICM, plugs and wires, it worked for one weekend (and I won the event). Last weekend it broke two pushrods and I installed a new set on Friday afternoon.

Today I drive to the track in the rain, and go to the gas station two miles down the road to fill up (I'm 99.5 miles away from home), and the car refuses to start.

I do not hear the fuel pump turning on. My guess is it is the relay and not the pump. Anyway,I have been replacing relays and pumps annually. Seems like most people do not have to do this.

Fortunately for me Triple A Plus tows 10 miles and it started raing again so the event ended up being cancelled.

Where do I start to look for a cause for an annual fuel pump and/or fuel pump relay?

Uncle Ted,
Sorry to hear of your misfortune.

Seems like us New England guys either have bad luck or no luck at all

Have you thought of running one of those racetronix fuel pump wiring harnesses? If interested contact Lonnie Pavtis as he is a distributor www.westol.com/lpavtis "E" mail lpavtis@earthlink.net

I had a similar problem with my Z not starting and it turned out to be the aftermarket alarm that I had to have replaced.

Thanks for the advice Marc. I just have this nagging feeling if something keeps taking out the stock, (lifetime warranty) pump that the problem will just be more expensive with an aftermarket product. Something must be causing the pumps to burn up in the first place. Heck, 47 pounds of pressure isn't that much...

Please enlighten us common folk as to how you get a lifetime warranty on stock(I read OEM) electrical parts?????

The only place I know of that has a lifetime warranty is the cheap S@#T auto parts stores like Advance or AutoZone and I wouldn't be caught dead buying crap from them so please tell us.

Pump came from the dealer. They installed it. I am on my third pump in three years. They like it because there is a hatch opening in the back so they can change pumps in about 1/2 hour and get to bill GM warranty for about six hours.

Do you consistantly run your tank empty and then fill it up????

TedH

Yank is always full. It is the only way I can keep exactly the same weight in the car because I have no fuel gauge.

So what's the rest of the story? You claim to have a 383 that you race and have achieved 11.86. But the stock pump could never keep up with that demand. So what else keeps the fuel to the engine? Do you have more than one pump?

something doesn't add up.

My only guess, that something is adding load to fuel pump. May be it can be bent fuel line, bad luck with filters. It can possibly be clogged drenage tube in tank, so there too much vacuum happens in tank in process of sucking fuel from it (I am not sure whether f-body have smth. like this...)

Racetronix

It could also be that there is a large amount of sediment or rust in the tank. The other reason could be that the factory in-tank wiring is burnt / terminals corroded. These are two very common reasons for pump failure in the F-LT1 cars. They are simply getting old...

I would not waste anymore money on a stock pump. I am very happy with my Racetronix setup. Well thoughtout and professionaly crafted.

Customer service was top notch.

Thanks for all the suggestions.

The stock pump should have more than enough ***** to handle the flow of a normally aspirated 383 with 30 pound injectors. What I am trying to figure out is why I keep blowing the fuel pump relays, then a couple of months laterI will blow the pump itself, and the gas gauge hasn't worked in two years (always stuck on full).

I will checl out aftermarket pumps. I would feel better about it if the stock pump wasn't able to handle the load. I do not know why an aftermarket pump would not burn up like the stock product.

I emailed acopy to Ty to have him send you a response as well. I'm thinking bad ground or power source. I went through two pumps back a few years ago my friend at Woolwich Chevy Then Brothers! Found I had a bad ground burning out the pump! I don't know I'm thinking wiring if your going through pumps like that. Good luck i wish you well!
