01 Civic LX Auto

Problem:
1. Car cranks and idles from 1000 to 2500 rapidly for a few times then drops to zero and just dies
2. When shifting, each gears shifts hard
3. P, R, N shift selector lights is on. Drives is not on.
All fuses is good.


-One morning, when shifting into gears, car shakes hard.
-Check engine light came on
-Tried to scanned it with two different snap on scan tools and neither could not "detect any communications"
-I changed the main relays and it didnt fix anything
-I read up online and find out it can be the ecu
-I orded a ecu and had the immobolizer programmed to the ecu at a honda dealer
-Car cranked and idles fine,a few days and the problem happened again
-The checked engine light came on again and I was able to pulled these two codes (P1298 and P1324)
-This morning I went to pull the codes again and neither scanners could not "detect any communications"
-I read up online for more info and found out the P1298 (Electrical Load Detector Circuit High Input) was pretty much a common problem. So I ordered a new ELD (electronic load detector), installed it and went to crank the car and the problems still exists.

What should I do now?
