Ive owned a Grand Cherokee overland 4.7 h.o LPG conv about 4 months, absolutely love the car and love driving it.
Recently i was out and the battery seemed to struggle starting but did start, i went home , took the car out again next day and again the battery started like it was nearly dead, the car would not start the following day. I assumed the battery was naf so bought a new one, charged it to make sure it was 100% and put it in the car. Still would not turn over at all, dash light wearnt dimming or anything and i know the battery is 100% and is the right battery. It is like the car is not in park and therefore will not start or similar. any ideas, i have £100 worth of fuel in and want to drive it
