oh right on. yeah we tried swapping conversion harness.still same issueOBD2a and OBD2b ECU plugs are the same, just the pin outs are different.
These are the OBD2a and OBD2b ECU plugs:
This doesn't answer the question. What type of conversion wire harnesses have you tried? OBD2a or OBD2b or both? If both harnesses that you swapped were the wrong type, you would not expect the problem to be fixed, right?oh right on. yeah we tried swapping conversion harness.still same issue
obd2b-obd1 we tried 2 diffrent onesThis doesn't answer the question. What type of conversion wire harnesses have you tried? OBD2a or OBD2b or both? If both harnesses that you swapped were the wrong type, you would not expect the problem to be fixed, right?
Yeah just looked at it again, it is black w/ blue on the iacv.I wanted to verify that no sensor connectors were swapped. They look fine, though you probably misread the IACV, which has Yel/Blk & Blk/Blu wires.
yeah using obd2b to obd1 jumper and no modifications.no tune up due to it ran 100% in the teg the day we drove it into garage to rip it out.plugs are all right ronj and us tried it yesterday but we ll swap them for testing sakes. yes its p75 ecuJust because it worked for someone else doesn't mean that it will work for you. I had a B18B in my Civic DX using the Civic's harness, OBD2A, to an OBD2A P75 ECU without any problems. The ECU doesn't care what the engine is just as long all sensors are present. You mention that you are using an OBD2B harness so I'll assume that you have an OBD2B to OBD1 jumper harness although you failed to mention that bit of critical information.
Are there any modifications done to the engine? Did you do a tune up before you dropped it in? Did you check it's compression? Check that you havne't plugged the TPS plug into the MAP sensor and vice versa. They're the same looking and easily mistaken for eachother. And yes, I'm telling you to go to your car and switch these 2 plugs around for the sake of testing. Is it a P75 ECU that you are using?

lol let me know if u get it going... ill do the same if i get mine fixedbump for the same problem lol
whoa thanks for heads upIf the wire colors in connectors match the sensors, don't do any connector swapping. otherwise, you risk frying the ECU.
jumper is not bad since ive tried a knowing working one.and still runs the sameAny possibilities of you removing the jumper harness/OBD1 ECU and using the OBD2B P75 ECU? Could be a bad jumper harness too.
