Question about 1998 Jeep Grand Cherokee
Engine light on can be a lot of different things. But first, fid the gas leak! The fuel line is a combination of steel and in some places rubber lines. It is likely that the leak is in the rubber part of the line. The tank is usually protected under the vehicle by a steel plate that first must be removed on Jeeps. I don't know what part of the car the gas is leaking from, but if it near the tank at the back, its is probably where the line comes from the tank or where the filler pipe enters the tank. You will just have to get under the vehicle with a flashlight and look to see exactly where the gas is coming from. You may have to remove the bolts holding the tank cover on, it is heavy, so you might want to have a floor jack under it with a 2 by 2 foot piece of plywood between the steel plate and the jack. That way you can lower it to the ground safely. Do the same thing with the tank. You will have to disconnect the fuel filler hose before you can let the tank down. There is a clamp at the tank that hold it on. Look for leaks and replace the hose that is leaking. This is a critical issue. Gas and hot exhaust pipes can set this off into an inferno. Now back to the engine light on. A gas leak can cause the light on because it may show up as an evaporative system leak. It's like leaving the gas cap off. If you want a better idea of why the light is on, drop by an Autozone or Advance auto store and they will usually hook it up to their code scanner for free. Without the code readout you have to just guess at the cause for the light.
