Not sure how to put this question but here goes.
I have taken the engine and "all" the wiring harness out of a 90 model Sentra and put it in an 87 model Sentra. The 87 had a carb. The 90 has TBI. The problem is not getting fuel to spray thru the Injector nozzle. Getting fuel up to Injector but won't spray. Have checked Injector for ohms and it is within specs.
Chilton doesn't give the voltages that are on the Injector plug in on TBI.
Just says check with specs. but none are there in the manual. Knowing the voltage there would help as then I could check it. Have cleaned Injector also.

90 engine, I guess it is a GA16i. Have you also changed the fuel pump? My guess you do not have enough pressure on the fuel line. Also, the 16i injector is low impedence and the resistor box is usually on the firewall(it is a silver box) . Check to see if your donor car still have it and wire it accordingly.

That is the engine # and changed the fuel tank as well so fuel pump there. Already changed the whole wiring harness so resistor is there also. Just need the voltage going to the injector, I understand it is a pulse voltage but would like to check it to make sure it is within specs.
Thanks for the suggestions but already done.

Why didnt you upgrade to a GA16DE? Was it just you had an old 90 doner sentra with a good ga16i and you were bored? How many miles is on the ga16i?

[color=blue] Had an 87 model in good shape with blown engine, found a 90 model , beat up but good engine, just rebuilt. So decided to swap the engines out. Little did I know the trouble I got into. Had to swap all of the wiring harness and fuel tank. Few troubles there but got it handled after a few modifications, such as headlights are different hookup. Finally got it running now the transmission isn't working like it was, only have 1st and 3rd gears, so have adjusted the shift arm, now have 1st thru 4th but no reverse, lacks just a little more adjustment.[color/]

I wish I had a donor car like that. But I already have enough junk in my yard.
