If a 1990 dodge 150 has computer problems can you bypass it?

No, you cannot reliably bypass the computer system in a 1990 Dodge 150 to the extent that the vehicle will operate safely and properly. While some very basic functions *might* work without the computer, the 1990 Dodge 150's engine management system relies heavily on the computer for fuel injection, ignition timing, and other crucial aspects. Attempting to bypass it would likely result in:

* Poor engine performance: The engine will likely run rough, have low power, and possibly stall frequently.

* Poor fuel economy: You'll get significantly worse gas mileage.

* Emissions problems: The vehicle will likely fail emissions testing due to excessive pollutants.

* Damage to the engine: Incorrect timing or fuel mixture can lead to engine damage.

* Driveability issues: Other systems controlled by the computer, such as the transmission, might malfunction.

Instead of trying to bypass the computer, focus on diagnosing and repairing the computer issue itself. This might involve:

* Checking fuses and relays: A simple blown fuse or failing relay could be the cause.

* Inspecting wiring harnesses: Look for damaged or corroded wiring.

* Testing the computer: A professional mechanic can test the computer to determine if it's faulty.

* Replacing the computer: If the computer is bad, it'll need to be replaced with a compatible unit.

Trying to "bypass" the computer is generally not a viable or safe solution. It's better to address the underlying problem. A qualified mechanic specializing in older vehicles is your best bet for diagnosing and fixing the issue correctly.
