Ok so my car has this problem *92 EG* I shut down my car last nite parked it,This morn Solid CEL and cranked but no dice.

I thought it was a bad ecu so i put my hondata unit in and it did the same thing.

well now i wanted to know if my hondata was broke.so i took the hondata unit from my roomates car *delsol LS-V* I put in my po3 ecu runs fine ok..that ecu is ok..i put in my hondata ok that works fine too..go to put my roommates hondata back in and solid CEL..so i put mine in SAME THING.

So now the Delsol is in limp mode and solid cel with both hondata ecus, but runs fine with the po3

I swapped the chips on both ecus and tried every combination Solid CEL and limp mode.

Im sorry is this is somewhat confusing..But any help wold be AWESOME

 

so i fixed brandons car the rom got eraced some how..

now mine has some sort of main relay problem..when i plug it in the CEL dims.
