The JBE (junction box electronics) has failed. This has caused the fuel pump to stop responding. I'm not sure if my mechanic still has the original part. It did this in the street after backing out of the driveway. It could have been deadly had it happened on the interstate at 70mph. The unit has been inspected by a third party electronics repair shop and cannot be repaired. There were no warnings until it stopped working in the street. Vehicle has not been repaired, because available parts are diverted first to warrantied vehicles.

pre-purchase inspection list. Back to the
