Hi all, I have been transferring a complete B18C4 engine and LSD box into my EK3 and seem to have hit a small snag. The engine is installed and works fine except for the fact that the fuel pump won't activate without a constant feed from a battery lol OK let me try to explain, I have a P28 ECU from the donor car.... This works fine, however what we can gather is that the fuel pump relay isn't connecting properly to the ECU so therefor not telling it to prime the pump and feed the engine. This is the lead that goes from my cars wiring loom to the ECU, my original connector has all the right wires but it seems that the engines loom is missing the required wires to connect it to the ECU? I have an OBD1 ECU with a wire harness, notice only 2 plugs connected, this is also a worry as the engine ran in the donor car and this is the same harness? Now if i supply the fuel pump with constant power from the battery it runs fine (apart from no rev counter) however we don't want to run it this way in case we come across problems..... So has anyone fitted a B18C4 to a Civic EK3 and experienced any of these issues?? Any help would be gratefully appreciated as I am totally stumped lol. Thanks all.
