I have an 88 pickup and I put a 92 motor in it and used my ecu and wiring harness. I changed the sensors from my old engine to the new one and I'm getting codes 21,22,24,31,41 and 51. I know what the codes mean and I've replaced the tps and the maf but still codes and it won't start. I did cut the plug off of the tps and used the new style but it didn't work so I went back to the 88 style. Can anyone help!!?

Test the ECM/ECU, specificly I'm guessing you're geound isn't hooked up. (E2/E21)
