96 LT1 Camaro

[Beanmachine7000]

Alright, so I am supposed to sell my Camaro today... I go start it up (been sitting about a week)... Runs fine (takes a while to start), once warm and out of open loop, it starts missing and running like crap (seems to me that it's not getting fuel), dies... Won't start again unless I mash the pedal, and won't stay running unless I keep the pedal down... I don't have a clue where to start... Diagnoses isn't my greatest area...

I'd appreciate it if I could get this fixed today as I really need to get rid of this car... Thanks...

I agree, it sounds like a fuel problem. Do you have access to a fuel gauge to check the fuel pressure? I will assume your regulator has a vacuum line going to it, I would pull that and see if it is spitting fuel out of the port.

the lt1 has a test port toward the back where the fuel rails crossover. it has a shrader-valve (i removed my shrader valve because that's where i tapped into for my wet nitrous kit) you can rent a fuel pressure gauge from autozone for nothing more than a deposit. screw it on and see what your fuel pressure is, and if it changes simultaneously during your symptoms

Ding, ding! This hit me about 5 minutes after I posted this (well, after my dad got home and I was outside the car when he started it)... I'm currently working on putting a new FPR on it... It was spitting fuel out the back running waaay too rich... Good lord, I forgot how hard it was to work on this car... One reason it's going...

Yeah, it's been a while since I've seen under the hood of the Camaro's, but I remember half the motor seemed like it was under the dash. I just went through all of this on my Mustang. It ran "OK" after it ran for a minute or two, but it ran extremely rich. I'm 99.9% sure this is what killed my Magnaflow catalytic converters too, so luckily you found it sooner.

yep, lt1 camaros have 2 1/2 cylinders that sit behind the bottom edge of the windshield

It was pretty obvious when my dad had it running and I walked outside and it was smoking out the exhaust, and spitting out raw fuel lol... I've been chasing around a rich condition for probably 3 months and it's just been too cold for me to mess with it, until it failed completely...

I swear it's the only car you have to unbolt the engine and lift it up to change the plugs... Had to take the fuel rail off to get to the FPR, to get the fuel rail off had to unplug the entire injector harness, half the engine harness and a billion vacuum lines (I swear), lol... Oh well... It's done...

Ahh the good 'ol LT1. I had one in my '96 Caprice. It was a police car. Damn I miss that car.(not as hard to get at the rear in the caprice) Talk about a peppy engine. If I had the cash, I'd buy it off you man.

Had a guy buying it today, backed out, guess I'm trading it for a Heep now... Oh well... It will get me and my stuff out camping

What were you asking for it? Miles? Condition?

 

[Beanmachine7000]

$4,000, 148,xxx, average condition for mileage and age... Nothing outstanding wrong with it...

If you were here, you'd see the "dream bubble" over my head right now. lol

its the only vehicle that the book quotes out 10+ hours shp rate for plugs/wires. and i found that un bolting the k-member and lifting the body off to be the easiest way to do plugs.

HOLY HELL!!!!

 

[cammeddrz]

HOLY HELL!!!!

that is no joke. a basic tune up is something like 10.5 hours shop rate. a guy doing it in his driveway can expect to spend an entire weekend to get it done
