whats up HT im having a weird issue with my 97 ek. been having this issue for quite some time now can't remember when it first started. anyway, my problem is the car wont start without a jump or pop. weird thing is, i ended up buying a brand new battery and the car started up perfectly for about a week and now this again. i changed the starter, car started up first try then after that nothing, back to square one. I had my alternator / battery tested and both came back ok. i noticed when im driving the car my cluster lights would flicker every once and a while and my entire dash would go off including my radio. i tryed taking my radio out to see if that was the problem but nothing. still the same. what direction should i go into next? im really stuck on this and i feel like fixing this once and for all really dont wanna bring it to the garage ive fixed everything on my car for the past 3 years that ive had it i cannot figure this out please help
