weird electrical problem..need help fast
 

i have a 92 civic cx with a b18b motor. i reused the stock civic harness. car is boosted but hasnt been driven..has about...20-30 miles on the new motor. ive had no problems..i drove it to the exhaust shop and home with no problems. then it sat for a week or so as i waited for misc small stuff. it would start and have no problems. then 2 days ago i get my new ecu and basemap..my last ecu was chipped and had a basemap but made my car run horribly..like i couldnt even get over 30-40. i drove on the new basemap with zero problems. car drove fine..i pull into my driveway,go inside for about 20 min. come back out and try to start the car and its dead..it just kept clicking and wouldnt turn over. i had a pretty new battery and alternator and starter on the car..about 3-4 months old. but i replaced the battery and alternator and it fired right up today. drove around town..broke it in because im supposed to get tuned tomorrow. i drove on the highways and local rods. stopped at a friends house and sheetz. i then go home but stop at mcdonalds for a friend. as im going down the road my tach and speedo go crazy and then just stop working..i park into a spot..turn the car off, then try to restart and it wont start. we go inside for a bit and wait a good 15 min as he eats and i call around asking what could be wrong. we go to the car and it starts right up. as i pull into my driveway again,my tach and speedo stop working but the car still runs. now im stumped and have no ------- clue what is wrong. id appreciate any help guys

Where are your grounds? The only true ground is the engine block. Nothing else. OEM's are cheap and run grounds to the chassis which is fail.

Your problem is going to be a ground and/or connectvity issue. The multiple symptoms suggest improper ground though.

i have another problem tho...when i decelerate or im cruising....or accelerating to around 2000 rpms theres like a clanking..but if i get on the throttle or the cars under load theres no clanking issue or noise..its makes the gas pedal vibrate...like somethings knocking it..ca runs fine..car doesnt shake but has that clanking/vibrating
