Common 1990 Isuzu Trooper ii problems

The Isuzu Trooper II, produced in 1990, is known for several common problems that owners have reported. Here are some of the most frequently mentioned issues and their details:

1. Warm Start Failure: This problem is often caused by failed fuel injectors. The Trooper may lose power and fail to start again while the engine is warm or hot. Injector replacement can be challenging, but there are online tutorials available to guide the process.
2. Engine Oil Light Illuminated: If the engine oil warning light is lit after filling the oil levels, it may indicate a leak in the differential. This issue tends to occur around the 55,000-mile mark. Replacing the differential can help resolve the problem and save on high mechanic fees.
3. Excessive Fuel Use and Rough Idling: High fuel consumption and rough idling are often signs of a damaged intake manifold gasket. This part is usually available for the Trooper, and installation is relatively straightforward.
4. Ticking from Valve Train: A ticking sound from the engine valve train area is likely due to varnish build-up in the hydraulic lash adjusters. Using a higher quality oil can help resolve this issue.
5. Oil Leak: A faulty front crankshaft oil seal is the most common cause of oil leaks in the Isuzu Trooper II. A revised design is available to address this problem.
6. Rattling from Front of the Car: This symptom is often caused by timing chain tensioners wearing out faster than in other vehicles. Replacing the tensioner can help eliminate the rattle.
7. Power Loss and Check Engine Light: Power loss and the illumination of the check engine light can be indicative of a failing catalytic converter. This issue cannot be repaired and requires replacement with a new catalytic converter.
8. 4WD Indicator Staying On: If the 4WD indicator stays on even when in 2WD, it may be due to a faulty vacuum hose, solenoid, or engine valve. Replacing the faulty part can help resolve the issue.
9. Differential Leak: Oil weeping or leaking from between the two rear wheels where the axle meets the prop shaft is a sign of a leaking differential. Replacing the differential can stop the leak and resolve the issue.
10. Fuel Pump Failure: Fuel pump failure can result in starting problems and higher fuel consumption. Replacing the fuel pump can help restore the Trooper's performance.

In addition to these common problems, potential buyers of a 1990 Isuzu Trooper should also be aware of rust issues, particularly in the frame and body. Regular maintenance and inspections can help identify and address these problems early on, potentially extending the vehicle's lifespan and ensuring safe and reliable operation.

Unfortunately for Isuzu, mid-size classics like the Honda CRV and Toyota Rav-4 essentially cornered that market before they could find footing with their oddly conceived Vehicross and other compact models.
