99 villager no injector pulse
 

some other guy was working on it and he couldnt get it running for two months so they bring it to me. i check spark, got it. i check fuel, have everything but injector pulse. so i spray starter fluid and still wont run so i check timing, its right. so i set it tdc and pull dist cap, way off. so i set the dist to number one with eng at tdc. spray starter fluid and runs like a champ. when i first got the van i notice alot of grass and leaves under hood like critter nesting. pull intake and voila, critter chewed up injector wire. seperate injector wires and unplug all non essential sensors and pulse comes back. repair wire with wire laying around( not sure if it has to be certain kind of wire) but pulse goes away? switched pcm with known good pcm from another van, even put pcm from this van in other and it works. pulled harness in engine bay and checked continuity and thats fine. its got me kinda baffled????????
