I found one of my fuel injectors to have an ohm reading of 3.8, so I am figuring I should replace the whole set while in there. What is the recommended injector to go with? Any other recommendations that be done while in there? The vette is street driven, autocrossed and track days. Its...
Well, no one including myself guessed this one correctly. It was a simple and common problem which a true corvette expert diagnosed over the phone in less than one minute. I was amazed at his accuracy but thank God for it!!!!!
I also pulled off each injector's electrical connection one at a time and ran
the engine after each was disconnected. My thought was that if it was a "bank
fire" system and if one shorted then they may all be shorting. Unfortunately it
didnt seem to make a difference at all.
Am I correct in...
Well, if I am checking my injectors correctly for an Ohm reading here is what I got: 13.9, 13.3, 12.7, 16.3, 12.9, 16.3, 15.3, 12.6. So do I have injectors going bad? I read 16.0 as the cut off to stay above on this reading.
however, while I was on the injector near #1 cyl, I saw a little...
So, finally have a fuel pressure guage that works. At key on, but engine not running I had 40 psi. Running at idle I had 37-38psi. When she started to slow her idle like she was dieing the pressure would increase to about 40psi. I would then give it a blurp of the right peddle and she would...
Ok, So I finally got a chance to mess with the vette today and here is what I have found out. Fuel pressure relay looks to be good as a new one made no effect. All fuses are fine, gas is less than 2 weeks old.
While I was checking and trying things I noticed that when I turned on the...
Played around with a fuel pressure guage. the first couple times I tested it I got no pressure at all. Either at key on, or after at as I ran the engine. (She still ran the same, hard to start but would then die shortly after.) Since it was a loaner I bought my own and tonight only hooked...
Thank you for your insight & direction. I went & picked up a fuel Pressure gauge , DVM, found my old hayes manual too.
I was also looking at an Actron cp9185 elite scanner, its said to do both obd 1&2. Is it a good scanner to buy?
Also, I had no fuel pressure on the guage when I tested the...
I hate to admit it again, but being a backyard mechanic I have no idea how to check for a vacuum leak. However the vette was given a complete tune up in the last 4-5k miles which included plugs, wires, cap, rotor.
I am starting to wonder if its a fuel pressure issue? If so where do I start...
Just installed a new ignition module, no difference she is still dying on me & running bad. I did the jump a-b wire and still no codes thrown.
Any suggestions as to the next area or how to diagnose from here?
Point well taken John. Yes, for now I plan on using standard replacement parts since I am having a driveability issue. That way I can at least figure it out & get it back going down the road again.
It is frustrating sometimes how you think your improving things with an aftermarket item and...
That sounds like a good place to start. What suggestions do you or others have as to performance upgrades to the ignition on the currently stock vette engine? I was using an MSD coil but had problems with the tach reading correctly. Should I use the MSD again and if so what does one have to...
Hello,
I have an 89 Coupe 6 spd, I drive about 6-12 times a year and while this year I have driven it quite a bit more. The vette is all stock with 71k miles & have owned my vette for over 10 years. Recently had an issue where it is dying, cutting out, rpm dropping, rough idle and when racing...
I have an 89 vette with the same problem. However I put the MSD coil in about 4 years ago and went through months of back and forth with MSD. They sent resistor after resistor and nothing fixed it. Finally I got a RGA authorization but never pulled it out to return it.
Problem still exists...
