I've never had any problems with this car...

Went out to start the car, started right up and then died immediately. The car just cranks now. It has spark, and it has air flow. I cleaned the mass air sensor and it started for half a second and died again.
I took apart the whole air intake system looking for any clogs, nothing.
I checked all the injector wiring just in case a rodent or something chewed them up (happened to my truck more than once).
It has a about a full tank of gas.
It's not the timing chain unless those can magically break by sitting out in my school parking lot for 6 hours.

Perhaps it could be the fuel pump? If so, do any of you think this replacement pump would work? --> Replacement Fuel Pump

Like I said, this is my daily driver, so I kinda need this back on the road yesterday. It's sitting up at my school for now... So all/any help is very much appreciated!
Thanks!

 

can you hear the fuel pump come on for a couple secons when you first turn the key on? try sprayin a little starting fluid in the tb if you have any to see if it is lack of fuel. you would most likely burn that fuel pump and regulator up in short order. all that pressure and volume will create heat if its run through with a small amount being used. as it says its intended for a 600 hp motor. check to see what rockauto has and use the code provided somewhere on here and save more bucks. be right back

 

I bought my fuel pump from RockAuto for like $90 I think. Also you can check your fuel pressure by opening the valve on your fuel rail. It's right behind the y-shape on your upper intake manifold. Easy to find. It may have a cap on it. Get in there with a screwdriver of a key and push it like you would a valve stem on a tire to see if there's pressure. If not, you likely have a clogged fuel filter or a bad fuel pump.

 

here is the sticky, its in the vendor section, good for 5% off https://camaroforums.com/forum/vendo...nt-code-69023/

 

This is the check valve on your fuel rail. Like I said before, it's like a valve stem on a tire. You can push in the middle of it to see if you have pressure. You can also rent a fuel pressure tester at your local Autozone or Oreillys for pretty cheap to see what kind of pressure you have, whether it's too much, not enough, or just right.

 

you might try unplugging the maf. should run in open loop and ses light should come on. have it scanned for trouble codes if you can

 

Update:
I ran throttle body cleaner through it several times; it started up for a second then died. Just burning the cleaner more than anything.
I put an automotive stethoscope up on the fuel tank and flipped the key on. I didn't hear a thing...
I just got the notifications from this page today so I'll try these ideas out later and keep you updated.
Thanks for your help!

 

Craby: the 3.4 doesn't have a maf.

 

That fuel pump says it it adjustable from 0 to 140 psi... It also says it will support up to 650 HP...

"140 psi high pressure fuel pump supports up to 650hp"

"JDM adjustable Fuel Pressure Regulator from 0-140 Psi for maximum fuel capacity"

Am I just interpreting that wrong? It sounds like I can tune down the PSI from the 140psi it comes at to the 41-47psi that the Camaro pumps are supposed to kick out...
I'm just trying to figure it out. I have never worked with fuel systems, I've never had a problem with them before.

 

yes and when you turn the pressure down the extra gas goes through the system, lots of it with a high volume pump, even more with a motor that burns very little fuel. im not saying it wont work, if the fuel pressure regulator fits it should work. im sayin its overkill, maybe to the point of causing the pump or fuel pressure regulator to fail sooner rather than later.
