While driving all the light on instrument panel will all light up then the transmission will shift hard. The car will not crank at times and when this happens its a guarantee the transmission will shift hard. The evap sensor is faulting because when I put fuel in the vehicle seems like it does not want to crank. The evap problem does not seem to be related to a possible computer malfunction. We have had the fuel pump replaced by a local licensed mechanic.
The dash message says power steering. As I was excellerating in the on ramp of the highway, the rpm jumped up to 6,000 all on its own and now it will not shift gears, does not read any mph, and can barely go more than 20mph. This was unexpected and had no warnings prior to. Although it still functions (turns on, runs, has all power available, has reverse) it is ultimately disabled. Also, the fuel lines/ fuel pump failed causing a gas leak, making it a challenge to start the vehicle. I have patched the fuel line as a temporary fix. I have already replaced the lower control arms and the timing chains at my own expense.
Power steering went out while I was driving at a speed of 45 mph. I checked fuse and it was blown. I then but new fuse in and started car. The second I started the car the fuse blew again. The strang thing was that even tho the fues had blown the power steering continued to work until the car was shut off. Also my radio started changing stations by itself and airbag warning came across the dash then a couple days after that started I went to start the car and it wouldn't. Radio, outside lights and blinkers, interior lights, and dash lights would all still work, but it seemed that no power was getting to the starter nor the fule pump. At this time the car still won't start.
