92 camaro rs tbi 305. I have checked for fuel pressure and it's perfect, I have great spark and every ignition component is new. The fuel pump filter regulator relay are all new and the tank and sending unit. Had a mechanic looking at it and he told me there are no vacuum leaks or anything. So I'm stumped trying to figure out the problem. The car turns on but as soon as it's given gas it dies. I was told maybe the iac but the car runs off of starting fluid. So what could be the problem ? The mechanic is still diagnosing but i would like some help from anyone that can give me input at what to look at.

Has he checked the tps ?
If it is the iac sticking open the vacuum leak causes high idle, stuck closed lo indie.

Yes, he said it was working fine I had replaced it a while back.

Check the 2 Injector fuses. If it runs on gas you spray, Injectors my not be spraying. HTHs

I replaced both of them but I didn't do the reset procedures. Another memember told me if the car is running off of starter fluid that the iac should be fine. Mentioning I didn't reset or fix both correctly could that very well be the problem. And if both were off would I be getting exactly the symptoms I am right now?

@Bob88GTA both injectors are spraying, but when you start the vehicle and give it gas they cut off. So I know I'm getting fuel with the right pressure but it cuts off once running

Could be a bad map, it would need to be tested.
Any codes ?

Anthony0128

The car has a map sensor not the maf & nope none at all

I'll ask him to check it but wouldn't I have a ses light on?

A faulty MAP sensor can cause some fuel delivery problems and not turn on the SES light 33,34 malf .
A faulty Icm can cause odd issues as well.

Anthony0128

Well I'll make sure to check it out, I'll let you know if I find anything or if the mechanic does. What would cause this to go bad though ?

Anthony0128

So I spoke to another mechanic and he said it might be the vats not letting the car run. That I would have to reprogram the key the computer or something along the lines of that. Is it possible?

If it was VATS the starter wouldn't work and it couldn't even try and start. You would just turn the key and get nothing and the security light would stay on

Anthony0128

So what could it possibly be then?

redneckjoe

sounds like a fuel delivery problem. i'll vote/guess a bad TPS.

Anthony0128

But the tps is brand new and it's not adjustable on a tbi. Mechanic checked it said it was good

redneckjoe

when you look in the throttle body with the car idling, if you give it any throttle it stops spraying fuel?

Anthony0128

Yes sir, it's like something cuts it off as soon as the car starts. Giving it gas just cuts it even faster. Which is why I'm confused because it has the spark and fuel pressure. Pump is 3 days old and sending unit in it is about a week old. Filter is new and regulator is too. Which is why I'm going nuts cause what more could it be
