fuel pump dying?, timing off? or....?

[wishuwerehere82]

You know whats funny though, the oil pressure gauge always shows good, i have read bad things about original gauges...hmm now I know why
off for 5 qts and filter.....
ps does anyone think this might have something to d owith original isue?

As you said, first things first. Try it after you get some oil in it and then start checking for puddles. If you cavitate the pump, the first thing that is going to be affected is the lifters. if they don't have pressure, all kinds of performance problems can manifest themselves.

I hate to think it's the ignition module; I have a new Petronix HEI I installed about a month or so ago. But, I am thinking it.

I took the carb out and cleaned it up this morning--a 1yo Edelbrock Quadrajet. Checked the fuel filter and everything else I can think of--to no effect.

It went down hill so fast (2 days) that I'm going to change the ignition module next--I can always return it.

Check your battery voltage, that can cause it go slower and slower if the alternator is not charging.

It was the ignition module! I put the new one in and the car is happy again!

I called Summit (where I bought the distributor from in November) and they said to return the old module to them and they'll credit me for it. The also said that I should have been told to install a ballest resistor because the Pertronix units are very susceptable to power surges.

All's well that ends well...

Man! You don't waste any time, do you?

Of course I'm in a hurry! It's 65F and not a cloud in the sky! I hated to waste a day like this! I'm off...

Yet another POS pertronix unit bites the dust story. When are people going to wise up and stop buying that cr*p?

Put your stock unit back and be done with it!

go ahead and rub it in photovette, im still here changing the oil ,(insert pic of me crying) it appears I had a bit of oil (looks about three quarts), I hope this was the issue as I dont have a timing gun and even if i did I wouldnt know how to use it

mike

 

[woobie1966]

changed oil, checked for leaks, took for stress test drive,....no issues for now

could low oil have been the culprit all the time?
will drive this eve to superbowl party, let you all know outcome

Super Bowl party? Yeah, if I drank and drove a 454, I'd probably pop in a Leonard Skinner tape and do donuts in people's lawns just for old time's sake...Let me know if you need a DD.

 

[woobie1966]

Party was fun, vette drove ok, no booze for me though. I am still holding my breath to see if problem re-occours. I hope i have seen the last of that problem.

Timing by Bubba

Here's a quick and dirty way to set "basic" timing for $0:

Remove #1 spark plug. Cover plug hole with end of finger. "Bump" engine over until piston comes up and air pushes on your finger. Verify by looking at timing mark on balancer-should be at or near "0".

"Roll" engine back by hand (grab belts/pulleys/balancer) counterclockwise until timing mark on balancer is at about 10 degrees BTDC. Connect spark plug to ignition wire, ground spark plug itself to intake bolt or bracket. . Loosen distributor clamp. Turn ignition on. Rotate distributor until plug fires (spark jumps gap). Tighten distributor. Your timing will be at or very close to 10 degrees BTDC-assuming points (if applicable) are set correctly. Bubba lives!

well, put about 100 miles on the vette since the oil change. The problem seems to be gone. Could the stuttering have been caused by low oil? I am no mechanic but I cannot see the connection between acceleration stumble and low oil, any ideas....

If there was no oil on your crankshaft seals, they will burn out and it will start leaking on your front and rear main seal...Glad to hear that you found out the problem with your dist.
