I have a Vitara Diesel that doesn’t start any more. Unfortunately, it has the code keypad installed, so you have to turn on the ignition first to start, then enter the code and then it usually starts. (If the battery is weak, it needs a booster) But the battery was completely full with 12.7V, at the start process it also goes back 10.7. Diesel I refueled when I pulled off the front tube on the filter that goes to the block front, it’s once told me If I pump over the pumpball diesel, it comes out at the filter. Does anyone have any idea what I could do to get it back on track?
