I'll try to keep it short. I have an 89 22re that i swapped into my 85 Toy last spring. The only part of the efi harness modified was to keep my guages working. It has been flawless until 2 weeks ago. On our last ride, i started blowing the main efi fuse. I went thru the harness trying to find any bad wires and found none. Replaced fuse to try to get back to the trailer and lasted about 10 min before it shut off. This time no blown fuse, it just died. I had 4 codes, all related to afm & tps. I reset the comp, checked codes and only code i get is 51-tps. I have replaced Just about everything electrical on the engine with new or known good parts and no change.( incl. tps, afm, all relays, comp, you name it it got it lol.) all wires have been checked with a meter and i have the correct voltages & ohms at all points on any circuit per the FSM. Still get code 51-tps. 44 psi fuel pressure at the rail, good spark, all fuses good, i'm lost. Turns over fine, tries to start but thats it. Anyone else have this before? Any thoughts or advice? i really don't want to go back to a carb.
