Just about done the 20v swap and the only way it will run is without the MAF. I went to the junkyard and got one out of a 90 corolla I think and tried that and it stilld doesnt run with it plugged in. The one out of the corolla was a newer looking one and didnt have a toyota part number so I couldnt check to see if it was the right one but it was the same shape and had the same pinout as the one that I had. The fuel pump does turn on when I push the flap in when its plugged in but I wont get spark. Should I get a new maf from work or is there something else that could be the problem?
