Did it run fine otherwise? If so I would suspect injectors but before I replaced them I would remove them and physically view them working or not working while your car is running. If you have good spray pattern then good if u ha e a stream or drip of something then at least u know u have to replaced that one or two or three.
LT1 Problem
The car: 1995 trans am w. auto trans
The problem: I let the car run out of gas, got it to a gas station, filled it with gas just to find that it would turn over but it would not start. I figured I clogged the fuel filter so i changed it but now the car will not stay running unless you keep revving the engine and even then it sputters/misses.
I checked my fuel pressure, it is around 41-42psi before I go to start it(which is just a tad low but that shouldn't cause it to not stay running right?), when I start it it drops to 38ish and then goes back up to 41-42 but right as it goes to idle it just dies unless i keep revving the engine.
My only thought was the injectors could be clogged as well? Anything else I should look into before I go off buying injectors?

Did you change the fuel filter?
Yea it worked 100% prior to running out of fuel, im gonna pull them tomorrow and check them out.
Yep, was hoping for an easy fix :x.
Just backing up usmc's answer, it does sound like the injector's at this point.
I know its to late ,but running out of fuel in a fuel injected car is really really bad news,and with the LT1 it seems even worse,my bet is dirty injectors.Depending on if you have a second car,you can remove yours and get them cleaned and recalibrated. Dont run out of fuel any more. good luck,ed
Ya i have a second car, i pulled them today and to be completely honrst they look like they have never been changed or even pulled and cleaned for that matter.I know its to late ,but running out of fuel in a fuel injected car is really really bad news,and with the LT1 it seems even worse,my bet is dirty injectors.Depending on if you have a second car,you can remove yours and get them cleaned and recalibrated.

I was thinking about buying the ebay ones that are used in mustangs as well but i read somewhere that i need to get heavier injectors if i buy those because the flow rate is different on them. Any thoughts/experience with these?
Edit: Around 150k miles..
I have never used him ,but I have spoken to him on occassion,
and that's Dr. Injector. He runs a service that rebuilds and recalibrates
GM throttle bodies and injectors,from what I understand he can turn
around injectors and throttle bodies in a couple days. He is also very knowledgable about fuel injector systems ,so if you were wanting to do a mod in the future he could direct you. good luck. ed

The fuel pumps don't like to run dry.
Ya know, most of my fuel pump problems happened after letting tank run dry. I recall running out while in line at costco and having to push it to the pump - up hill. The usual hard to start fuel problems began after that. Funny, my battery died once at the costco fuel pump too (same pump i think) - but i don't suspect costco has anything to do with it.:lol: But my fuel problem from this was hard starting which doesn't match yours.
Yours sounds more like the fuel filter. I would replace this first as injector cleaning is more work and $$$. And the dealer can clean the injectors includling the throttle body for like $150.
BTW always scan your codes before spending and repair money.
Good luck,

Letting your tank run dry in these early fourth gens tends to be really hard on the fuel pumps. Often they can just stop working. For future reference try not to run your tank below even 1/4 tank. The fuel helps keep the pumps cool and the dirt at the bottom of the tank. Do you have any answers yet?
Not anything other then reinforcing my thought on it being the fuel injectors. I pulled them and they are just filthy. As is the inside of the fuel rail. Any thoughts on cleaning the rail? I have it pulled completely out.Letting your tank run dry in these early fourth gens tends to be really hard on the fuel pumps. Often they can just stop working.

Do you have air available to you? I would just clean it with a good cleaner i.e. brake clean, carb clean, sea foam etc. You may have sucked up fuel tank debri into the injectors maybe not all but some. I wouldn't know how to clean the injectors. You can find some cheap at Texas Speed, WS6store and a few other places. I would give you mine but I just gave my old ones away...sorry!
Can you hear the fuel pump prime when turning the key? I would hate for you to spend money on cleaning / replacing your fuel injectors.
On that note check out this site lol ^_^

I also changed the fuel filter.
Thanks for the website it might come in handy
.Thanks for the info, i think i have some carb cleaner lying around and i have air so ill be taking care of that.Do you have air available to you?

I think im just going to buy new injectors and call it a day.
Would it hurt to get 30lb injectors if i am going to get it tuned soon?
Would it still run in the mean time?
