I just hit 160,000 miles on my camaro yesterday and as I was driving home traffic came
to a stop on the freeway my car started idling real low and died. It would crank over fine
but wouldnt start. No ses light either. After about 5 min it started and managed to get out
of the lane. I just wont idle and if i gas it it stumbles then it revs. Im thinking fuel pump.
Any ideas?

alternator?

If you were running your original fuel pump, id look at that first

Ya fuel pump and alternator would be my first guesses.

Yep check the Alternator... & Fuel pump.
The very first night I picked up my car I got stranded in the middle of I-15.

(I live in Utah and I was moving it from southern Utah to Northern, needless to say nothing is in Central Utah)...

So I had to hitch a ride with a rice burner who was kind enough to stop by.. lol

Yeah it was horrible.
I spent an extra $300 bucks that night, for towing to a city I had never heard of and a hotel room -__-

The damn alternator went out, luckily the seller felt bad and paid to get a new one in

Sounds like an IAC valve issue. They tend to gum up on high mile cars. Remove (from the throttle body) clean with carb cleaner, and reinstall. May fix the problem, may be an actual part failure. My experience is that dirty IACS will cause stalling when the RPMS fall to idle. This may also be accompanied by a smell of fuel.

that was going to be my guess. if you can crack the throttle a bit and it starts right up, then i would say IAC

(Just reading your post) & I definitely have the smell of fuel in my engine bay after its gotten to operating temperature..

Would you say that could be the IAC? (110k Miles)

Well my exhaust had been smelling little richer. I started it up yersterday morning and
ran fine for about 3 mins then it just shut off. After that I didnt bother anymore. Gonna
clean IAC when i get home.

Don't take this the wrong way but you just need to start running some diagnostics on it. I would say if it starts after sitting for a while that the fuel pump is fine b/c the hardest time a fuel pump is on initial start up where good pressure and volume is required. However, have seen them fail once they get warmed up. Put a pressure gauge on it when the car stalls and see what numbers you get.

Cleaning the IAC is easy and basically free. Make sure you clean the throttle body blade edges with some carb cleaner as well- the edges where it actually touches the throttle body itself because they get carboned up.

Lastly, you need to scan for codes. The fact that you say it ran fine for 3 minutes leads me to believe it is having trouble once it goes into closed loop like possibly a failing o2 sensor.

No codes,02 sensors replaced in Jan. tb Was cleaned but not the iac about
3 weeks ago along with maf, Spark plugs. I never had a fuel pump go bad so
i dont know what the symptoms are. Anyhow i ordered a walbro already,now
I wait for it to get here.

Did you fix your car yet? If not, reach behind the intake manifold and see if your MAP sensor popped out.

Not yet brotha been getting out of work late. Got my fuel pump
in today though gonna swap it saturday along with the spark plugs.

Man that pump's a lot of work, I sure hope it's the problem. Did you do a pressure check on it? It's easier than cleaning the IAC in my opinion...

iTrader: (26)

^^^ Was planing on swapping the pump anyway i even did the trap door mod awhile back lol.
Still gonna clean the iac. I got my fuel selonoid mounted on the fuel rail so its doesn't
have the schrader valve can i still check fuel pressure without it?

myk

iTrader: (4)

Wow man you got me. There's gotta be some other way to check the fuel pressure even with your 'mod in place. Anyone?

with a scan tool yes. pressure gauge, no

cut the fuel pump access panel, piece of cake
