April 28, 20205 yr Working on putting a donor EA82 SPFI engine from an unknown year model into a 1986 GL wagon 4wd 5mt. Have entire donor vehicle, which is an 88 GL10 4wd which received an engine swap before it was in my possession. Car was running strong before swap. As as mentioned in title, I have a no start issue and the LED on the SPFI control unit is blinking three long blinks followed by one short blink (I’m under the impression this refers to trouble code 31, TPS). I have spark at the coil and plugs, and fuel in to the pressure regulator, but when cranking no fuel is injected into throttle body (just pulled intake off to look in). Between the engine running in the donor and it having this issue I removed the TPS in the process of cleaning the engine. When I reinstalled it could I have done something wrong which is causing both the code 31 and the no start/no fuel injection issue? Any input is greatly appreciated! -Will
