right cylinder head is that passenger or driver side right side faceing away from front or right side looking at front of car beneath 6 and 8 plug are those front two or rear two what side?
sounds like i ran across the right person for advise thankyou i will check it out and catch up with you down the road for sure.
hey to broke ,following the line from the fan why is there a connection to ac are you sure the only activation for fan is sensor at 6 and 8 plug?
hey to broke to retire yea the previous arkansas hill billy owner of the car was not so bright, no oxygen sensor, and i got to compare the wireing harness to another 82 for the electric fan, looks like for what ever reason he completed the circut for the fan with the hot wire on the ac compressor so the fan would turn on as soon as the ignition is turned on, what an idiot, so i had replaced the sensor with a sensor switch from mid america now to undo the electric tape to see what all was cut and restore to original oh boy never buy on line unless you get to sleep with it first in person hard lesson learned!
Could that cause it to shut down when engine gets warmd up if not plugged inFront Or Rear and Left Or Right?
The right cylinder head is on the passenger side. All references to which side of a car is made from your sitting in the driver's seat and looking foreword. The switch that turns the fan on is located about 3" above the #6 and #8 spark plugs and is hidden by the heat shield that covers those two plugs. Many years ago I screwed a short 3/8" pipe nipple and coupling into my right-side head to extend the switch out beyond the heat shield so I could get to the wires easily without having to remove that shield.
The wires are joined together by a plastic coupling but my coupling broke (from heat) a long time ago. So I had to remove the broken coupling and crimp two 1/4" female spade terminals on my wires. As the switch is simply an ON/OFF switch it doesn't matter which terminals the wires go to.
Just my 2 cents worth, thak seems to be likely. I had mine (82 Pace Car) doing pretty well, but after I rebuilt the dist. The timing was off a tad. Unfortunately, the marks might as well be on Pluto. Been sneaking it in and am darn close. Starting better but wants to run rich for a minute. Replacing the thermostat now, as someone put a 180 in it instead of the recommended 195.I have 82 also having cold hard starts, I was told by mechanic that the timing was off, can timing cause this?
I dont know how to start my own discussion on this thing but have question for you about my 82. It runs fine but won't get up and go when you put the pedal down? I purchased it in Boise but live about 3000 ft higher and its cold. It vapor locked on me once.But in Boise it Did get on it when the pedal was floored? I think it needs new injectors. The gas they have put in for a long time has ethenol in it.What do you think?1982 CrossFire Injected Corvette
Okay pumper, I have owned my '82 for 23 years and I can tell you most anything you would ever want to know about the Crossfire Injected engine. For starters there is a temperature sensor that is screwed into the front of the intake manifold about 3" to the right of center. That sensor gives the computer the coolant temperature needed to adjust the air/fuel mixture for cold starts. Then on the firewall behind the power brake unit is your MAP sensor. The MAP sensor reads manifold vacuum and sends that information to the computer. Also there is a throttle position switch (TPS) mounted on the left side of the left throttle body. That TPS gives the computer the amount of throttle opening and should be adjusted to .525 volts. Then there is a O2 sensor just ahead of your catalytic converter and that tells the computer how rich or lean your fuel mixture is. As your engine is "fuel injected" you always start it with a closed throttle. The computer will automatically make your engine fast idle when the coolant temperature is low and will gradually slow the engine down as it warms up. There is a 25 micron fuel filter in the inlet line and it's mounted on the right side frame rail right under the passenger's feet. Your electric fuel pump is mounted inside the fuel tank and it will only run for 2 seconds when you turn your key on unless your oil pressure switch reads 5 psi or more pressure. If the pressure is there the fuel pump will continue to run.
Keep me up-to-date and let me know if you have any other problems. I'll be glad to walk you through them.
Check/replace the engine coolant temp sensor that is located on the front of the engine, just behind the alternator. It reports to the computer and controls how the throttle body injectors function, especially when cold (Acts like a choke).This is NOT the one that runs the temp gauge and located on the drivers side of the block. Keni have a 1982 crossfire that is all stock bought the car about a year ago, the car is a work in progress and runs pretty good for being as old as it is. the car has 62k miles i am working on getting it to run good and then i will turn my attention to the cosmetics i rebuilt the tranny replaced the plugs, wires, points and distributer, have put about 1500 miles on it since i bought it only premium fuel two oil changes and for the most part the car runs fair to good once warmed up however, the car is hard to start when it is cold it seems to not be going to a choke start up for the cold start, a couple of times on the cold weather start up the car starts up like a champ with a smooth high idle warm up but that has only happened a couple of times. i am ready to try to isolate my cold weather start up issues but i dont know were to start any suggestions corvette friends i need some help
