This is a post to say thanks to all of you that posted regarding fuel pump issues, just wish I would have paid attention to the suggestions sooner. First off, let me say that I have been working on cars of all types for at least 40 years and during that time I had thought I had seen it all. I purchased a 1982 corvette last November, (my first), from a gentleman that had done a lot on the restoration side but the engine was a dog. After going thru the list of receipts of items that his mechanic had put on and going thru what I know about timing, sensors, etc., the car still was not running right and that made me feel that the motor was just living on borrowed time. I was beginning to put together a list of items needed to put a carburated engine in it as I had went thru everything I knew and then some. Rough idle, bogging down on take off and surging out on the highway This Cross Fire was getting to me!!! One of the items that had been replaced on this car by the last owner was a new fuel pump and even though some of the threads on here say check your fuel pressure I just couldn't see how the pump could be a part of the problem. This was a NAPA branded pump and their stuff is usally a cut above the other chain auto stores. As my last effort a few days ago, (after becoming so angry I was ready to strike a match to it), I finally purchased an in-line fuel pressure gauge at my local Autozone and removed the fuel filter and installed it. Guess what? 6 1/2 pounds of pressure, I couldn't believe it! This was the problem. I ordered the AC Delco EP 241 for the 1985 Corvette and installed it this afternoon. Upon starting the engine and checking the gauge there was 15 pounds of pressure! I have just returned from driving for two hours and this feels like a new car. The rough idle, bogging down on take off, surging on the freeway are all gone. Check the pressure before you do anything else.
