Default Why me !!!! Help help




Here once again for help, 96 lt1 , im having some issues with my girl, when ever i crank her up she sputters for a very brief second
then clears up,almost as if it was carburated and loading up..
a couple of times i came to a stop and it sputtered dead..as i was
trying to start her back up acted as if i were out of gas,after sitting
bout 20 minutes or so im able to get her started..my car has
bout 130,000 miles on it,going to change out fuel pump and filter.

Anyone with suggestions on this matter feel free to leave a comment.

Oh yea anyone done this work yet, if so you can give me an idea
to what it involves..Thanks Guys

ok how about the question WITH WHAT LITTLE INFO I GAVE YOU
WHAT WOULD CAUSE MY CAR TO SPUTTER WHEN YOU CRANK IT?
THE TIMES IT HAS STOPPED ON ME, IT SPUTTERS RIGHT BEFORE IT QUITS, AND ON OCCASION HAS NOT STARTED BACK UP RIGHT AWAY
WONT START AS IF IT WERE OUT OF GAS.after about 20 minutes
i've been able to start it right away..im very confused ,not sure
what it could be..

During the times that it won't start is when you must test for spark and fuel pressure. That will narrow your search.

First take it to AutoZone or anyone that does a free scan and see if you are getting any codes. Next do a fuel pressure check. Put fuel pressure gauge on it (right side rear of engine there is a fitting for this). Turn on key without starting, pressure should jump to about 43PSI immediately. start and run it for a few minutes, note the pressure and then shut it off and see how long it holds pressure.

I am betting on at least one leaking injector. But that is purely a guess at this point.

To own a C4 and not have your own scanner is just not being prepared.

My Auto X-ray 2000 was the best money I ever invested.

As for your probs, I have a '95 LT1 that had the same symptoms. The codes showed it was a bad Opti. It saved me a lot of time and money in just replacing parts.

If it's the Opti, pay the extra $$$ and get a MSD unit - they're almost bullet-proof. Change the sparkplug wires, waterpump and all the hoses at the same time. You'll be glad you did.

the opti is located right under the water pump and is prone to failure.
it causes the problems you are describing.

If your car was in a hurricane, your opti probably got wet.

If money is tight then go with the AC/Delco from an autoparts store, stay away from reman and ebay. Are you sure it is the opti?

For once I agree with you. Since it fires up right away, I would say the FP relay in this case is fine.

If the fuel filter has not been changed in a while, start with that. That is a maintenance item that needs to be changed at a regular interval anyways.

If it starts immediately but chugs, I would start with checking for leaking injectors.

You need a fuel pressure gauge to do a leak down test.

thepartsladi on ebay has them...
I got mine from ebay for $99.00...and it was a GM part, but, NOT from thepartsladi.

Joebuck (the one I am am quoting) changed it over the weekend...he was well fed, and I was entertaining guests.

My opti went bad because when my car was transported here, the car hauler had the nose in the air and coming from Ga. to here... the driver encountered massive rain storms, forcing all the water up under the engine and pooling everywhere.

that was Feb./08, the opti lasted a month or two with approx 70 miles put on it in those couple of months.


Thanks again Joey!!!!
(ps. yer dad never did call me back).


Joey can change the opti in about an hour....though; the plug wires take 4x that time.....go figure!
