1.6 to sr20de b13 swap

[junkyardogb13]

i swapped a sr20 into my sentra91.the motor is installed and will turn over and fires with starter fluid.the problem is that im not getting any power to the e.c.m.,and the fuel pump doesnt come on when you turn the key.do ineed to swap out the entire under dash harness that runs from under drivers side of where the engine harness connects to the three plugs mounted on body.the motor is from 92 93 g20 low port the throttle body is under the intake manifold. i have two different e.c.m.s one from 91b13ser and other from the g20.the fuel pump is good also.PLEASE HELP

If the throttle body is under the intake manifold, then the motor is a low port motor. What year is the g20 ecu? If it's 94 or newer, you can't use the ecu anyway because it will be OBDII. You will need to use the 91 ser ecu. Did you use the se-r harness for the motor swap?

yes i used the ser engine harness.is there any way to wire this up without changing the entire underdash harness.the only difference i see with the motors is the sr20 from the g20 doesnt have the a.i.v . valve.thats why i thought using that ecm with it.also the motor is obd1 so is the g20 ecm.
