I recently got a 92 honda accord ex in trade. Its got a f20b with a 5 speed trans. The old owner sent video of car running just rich and after video it sat for almost a year. So no it wont start at all. I just changed and cleaned all fuel as in new pump,filter,fuel lines. Then i started to dig into the car and found the ecu is out of a 93 prelude so is intake and the block is f20b. I'm trying so figure out why its now back firing when trying to start? I was told i should just get a tuned ecu for it, but how am i supposed to tell tuner guy what i need when it all seems Frankenstein ? The wiring dont look bad i dont see any cut or spliced wiring?
