1990 Gmc G30 problems
The Chevrolet Van or Chevy Van (also known as the Chevrolet/GMC G-series vans and GMC Vandura) is a range of vans that was manufactured by General Motors from the 1964 to 1996 model years. Introduced as the successor for the rear-engine Corvair Corvan/Greenbrier, the model line also replaced the panel van configuration of the Chevrolet Suburban. The vehicle was sold both in passenger van and cargo van configurations as well as a cutaway van chassis that served as the basis for a variety of custom applications.
Produced across three generations (1964–66, 1967–70, and 1970–96), the model line was sold under a wide variety of model names under both the Chevrolet and GMC brands. The first two generations were forward control vehicles (with the engine placed between the seats); the third generation adopted a configuration placing the engine forward of the driver. The second and third generations shared powertrain commonality with the C/K pickup truck model line.
After the 1996 model year, GM retired the G-Series vans, replacing them with the GMT600-platform Chevrolet Express and GMC Savana.

Common 1990 Gmc G30 problems
The 1990 GMC G30 is known for several common problems that car owners have reported over the years. This article will discuss some of these issues in detail.
- Leaking Fuel Injectors: Fuel injectors can leak, causing the engine to run too rich. This issue can be identified by observing the fuel spray pattern on the throttle body. If the gas is coming out in a cone shape spray, there are no drips at all. However, if it is leaking, it will cause black smoke and tailpipe.
- ECU Failure: The Engine Control Unit (ECU) is responsible for controlling every aspect of the engine's operation and the car's driveability. If the ECU is bad, it can affect any part of the engine's operation. The ECU cannot be repaired and must be replaced if it is bad.
- Rough Idling: The GMC G30 can experience rough idling, especially when the engine is still cold. This issue can be caused by a blown head gasket, which can occur without causing oil/coolant mixing. A professional mechanic can check engine compression to diagnose the issue definitively.
In summary, these are some of the common problems that GMC G30 owners have reported over the years. Regular maintenance and timely repairs can help prevent these issues and keep the car running smoothly.
