OK here we go.. I bought a 89 crx with a B18a with grs trnas swap in it.. I has a 91 integra ecu and harness.. It ran and started great some one in the past moved battery to trunk and was not good at hiding wires and so on.. I removed battery Install a box and taped up wiring that was showing wire.. It sat for about a week with no battery I got it done but now it will crank, it has spark, and is getting fuel to rail.. I found that there is no injector pulse.. It will start on starting fluid so theres something else in harness or ecu I would guess.. I checked all wiring I touched and its fine.. can anyone help me out I need to know how to trouble shoot the harness to ecu.. or even the ecu.. is there anything else it could be to cause this..
