My 2004 Range Rover HSE was parked for a year and a half and was running fine when I parked it. Went to crank it after a year and a half and it’s turning over but won’t get no fire. I’ve changed spark plugs I’ve cleaned injectors I’ve checked all fuses and relays I’ve gotten a new key cut but the locksmith that cut the key couldn’t program the new key to my truck could that be the reason why it’s not firing? Please help!!!!
