Fuel pump? or something else?

[sawsda]

Lately I've been having alot of problems with getting my car to start.
Long cranks before anything, at points you can hear th engine WANTS to start, but just wont.
We thought it was the fuel pump, promptly replaced it, and were fine, for a while.
Now, we're back to the same issues.
Any ideas?
-long start
-sometimes fuel pump is LOUD (you can hear it over the radio at points)
-sometimes the fuel pump is barely audible when turning the key to ignition

Fuel pump o-ring? I have some issues like that, not as bad. only 3 short cranks and my car starts.

[sawsda]

That sounds eerily close to what im experiencing.

by any chance did you ever loose fuel pressure while driving? that happened to me, i might just have it worse lol

Shot in the dark, but I've been having trouble gettin the 02 to start dude to a bad gascap. Try opening the cap before to turn her over.

[sawsda]

fixed!
well, not really, i just rode it out lol

so far i've had no real problems afterwards so maybe it was just bad gas?

[Revo1]

Better keep a close eye, doubtful it was bad gas. If it were, I have a feeling you'd have worse issues... Hopefully it will keep running well, keep us updated man

i had to change the whole fuel pump on mine. no good.. but the car ran like a beaut when it was all taken care of..

I have same problem with my 94 3.4 manual 5 speed. A lot of my problems went away when I put on a new fuel cap. Some how my car seems to loose fuel system prime. To avoid long cranking I turn the ignition on but don't start. I put my seat belt on to give the system time to prime and usually starts quicker than if I just get in and immediately try to start the car. If the car has only been turned off for less than thirty minutes it'll fire right off. If the car has been sitting for a few days I usually turn the key on, wait then pump the accelerator once then hit ignition and normally it fires right off. My brother says he thinks its an O ring around a fuel injector or maybe the seal on the gas tank. My car never loses gas and I don't smell raw fuel? I don't drive my 94 enough to justify a lot of expense to find the problems but Seafoam seems to help a little if it gets hard to start.

Replace the gascap, and try turning on the AC power for a second before you crank the engine- just to let the sending unit do it's thing before you turn her over. This has been working for me.

I haven't had the pleasure of ridding myself of that absolutely annoying noise yet, by any chance did you replace the fuel pump with another one in your camaro?

I do almost exactly the same thing, but with me i have to:
1. turn it to ignition,
2. let the pump do its thing(its audible all the time now)
3. then crank
I usually have to repeat steps 1 and 2 about 6 times now before she turns over.

If I'm in cold weather i have practically no issues, no noise from the fuel pump, nothing

And another issue popped up, unless i'm filled up to about half a tank, when i idle at a stop light, oil pressure drops pretty alarmingly.

Short Version :

Car not fixed.
Cold weather helps the pump issue.
Hot weather sabotages the pump.
& new issue: Unless i'm filled up to about half a tank, when i idle at a stop light, oil pressure drops.

The hot weather bit causes me to think that maybe you just need to replace the pump. I'm no expert, but I don know that those pump are fuel-cooled, so if the fuel is hot, or worse- you're out of gas they're more prone to burn themselves out. Not that hot weather will ruin your fuel pump, but if it's already on the fritz...

I actually just replaced my old fuel pump because it had burned out
The other one never made the noise, just one day decided it had enough and quit lol

I'm seriously considering replacing it again, through warranty naturally

Yep sounds like a fuel pump my wifes 2000 V6 had this exact issue once he pump was replaced she was as good as new I hope you did the "Trap Door Mod"
