To check the MIL (Malfunction Indicator Lamp) codes on a 1990 GMC Suburban, you can use an OBD-I scanner or a paperclip for a manual method. Locate the diagnostic connector under the dash near the driver's side. Use a paperclip to short terminals A and B on the connector, then turn the ignition to the "On" position without starting the engine. The check engine light will flash a series of codes that indicate any trouble codes stored in the vehicle's computer.
very carefully
Yes it will, I own a 1990 GMC Suburban 2500 (3/4 ton) and it came from the factory with a 454 motor.
Disconnect the Battery. Negative prefered. Wait a couple minutes and reconnect. This will clear codes on 1994 and older. If the light comes back on, check the trouble codes and a repair may be needed.
You need to have it checked for codes to know what the cause of the code is.
If your 97 GMC Suburban won't start when it is hot outside, check the distributor cap to ensure it is clean. You should also ensure it has plenty of coolant.
Just follow the top hose, from the radiator, to the engine block. It will be at the end, on the engine block
You can disconnect the battery for about 5 minutes and this will clear the check engine codes stored in the computer. If the problem that caused the code has not been repaired the check engine code will just happen again. The only way to get the check engine light to not be on is to repair the problem then clear the codes.
