Jeep Backfire Problems

A backfiring automobile is certainly embarrassing, but a bigger concern is that it can also be a sign of problems with the engine. Backfiring on a Jeep can be caused by a number of malfunctioning parts that could disrupt engine timing.

Excess Charge

If your Jeep is backfiring, it could indicate a problem with your ignition. The ignition is responsible for sending an electrical current to the spark plug, which then allows the cylinders operate. Backfiring can be a result of excess charge being relayed to that spark plug. The plug creates that spark at regular and specific intervals so the fuel-air mixture in the cylinders combusts properly.

Fuel Injection

A primary culprit might be your fuel pump. The fuel pump moves fuel from the gas tank to your Jeep's engine. This must occur at a specific and consistent pressure level. If a malfunctioning pump allows the pressure to drop, backfiring may well occur. The solution is to replace the fuel pump.

Other Possibilities

One of the chief reasons for Jeep backfiring is a clogged fuel filter. Make sure your fuel filter is clean and replace it if necessary. It is also possible that the Jeep's distributor cap has been subjected to moisture, which could be causing the backfire.
