1990 Gmc 1500 problems
The fourth generation of the C/K series is a range of trucks that was manufactured by General Motors. Marketed by the Chevrolet and GMC brands from the 1988 to the 2002 model years, this is the final generation of the C/K model line. In a branding change, GMC adopted the GMC Sierra nameplate for all its full-size pickup trucks, leaving the C/K nomenclature exclusive to Chevrolet.
Internally codenamed the GMT400 platform, GM did not give the model line a word moniker (e.g., "Rounded-Line series" for its predecessor). After its production, the model line would informally become known by the public as the "OBS" (Old Body Style), in reference to its GMT800 successor. In starting a different tradition, the model line overlapped production with both its predecessor and successor; the model line again shared body commonality with GM medium-duty commercial trucks.
Over nearly a 14-year production run, the fourth-generation C/K was assembled by GM in multiple facilities in the United States, Canada, and Mexico. After the 2000 model year, the fourth-generation C/K was discontinued and was replaced by the GMT800 platform (introduced for 1999); the C3500HD heavy-duty chassis cab model remained in production through 2002. In line with the GMC Sierra, Chevrolet subsequently adopted a singular Chevrolet Silverado nameplate for its full-size truck line (which remains in use).

Common 1990 Gmc 1500 problems
The 1990 GMC 1500, also known as the GMC K1500, has been reported to have several common problems by owners. This article will discuss these issues in detail.
- Stalling Issues:
One of the most common problems with the 1990 GMC 1500 is stalling. Owners have reported that the truck will stall when idling, especially after about 30 seconds. This issue can also occur when the truck is put into reverse or drive without the driver's foot on the gas pedal. The stalling issue can be caused by various factors, including a faulty idle air control (IAC) valve, a malfunctioning throttle position sensor (TPS), a bad ECS module, a failing ignition module, worn-out spark plugs, a bad distributor cap and wires, a failing fuel pump relay, a clogged fuel filter, or a dirty carburetor. - Shifting Problems:
The 1990 GMC 1500 has also been reported to have shifting problems. Owners have complained that the truck will jump or jerk when shifting into reverse or drive. This issue can also occur when the truck is in second or third gear, causing it to chomp and shake a lot. The shifting problem can be caused by a faulty throttle position sensor (TPS), a damaged transmission, or worn-out transmission mounts. - Starting Issues:
Another common problem with the 1990 GMC 1500 is starting issues. Owners have reported that the truck will start and run great one minute, but then refuse to start the next time the engine is turned over. This issue can be caused by a faulty crankshaft position sensor, a bad camshaft position sensor, a weak battery, loose or dirty battery connections, a damaged starter motor, or a clogged fuel filter. - Fuel System Issues:
The 1990 GMC 1500 has also been reported to have fuel system issues. Owners have complained that the truck will experience a high idle, run poorly under load, or stall when the throttle is applied. These issues can be caused by a faulty fuel pump, a clogged fuel filter, a restricted fuel injector, or a dirty fuel pressure regulator. - Electrical Issues:
The 1990 GMC 1500 has also been reported to have electrical issues. Owners have complained that the truck will experience intermittent electrical problems, such as the engine not starting, the headlights not working, or the dashboard lights flickering.

In conclusion, the 1990 GMC 1500, also known as the GMC K1500, has several common problems that owners have reported. These issues include stalling, shifting problems, starting issues, fuel system problems, and electrical issues.
