AboutDavid Scott Expertise Questions regarding the advisability of different kinds of modifications to Samurai/Sidekick/Tracker or various kinds of off-road usage. I will not attempt to do more than provide links for questions about other Suzukis such as Vitara, Grand Vitara, etc. I may or may not give generalized advice for newer models, but have no experience regarding newer models, and will not attempt to give more than the most generalized answers for questions regarding vehicles later than '93 manufacture. I will however, if possible, provide a link that will help you contact a professional in your region.

Expert: David Scott Date: 7/28/2008 Subject: Suzuki SJ losing Power
Question Hi
I own a suzuki SJ JX 1987. The car is losing power on long runs which requires that I stop the car before almost complete loss of power. The loss of power is often accompanied by a strong smell of petrol. The problem does not happen when the fuel tank is completely full but starts again when the fuel tank goes below half full.
New and replaced parts:
Coil
Leads
Cap
Rotor arm
Fuel Pump
Vacuum hoses
Fuel filter
Rad and Fan
Plugs
Please can you help me diagnose this problem?
Thanks
John
Answer I had a similar problem on my Samurai. It turned out to be old fuel hoses between the body and the pump. Two years later old hoses on the top of the fuel tank caused similar symptoms. They were permitting vacuum leaks, and reduced the capacity of the pump to raise fuel from tank to pump level.
