Ok so similar problem with not firing on my original ecu, injectors 1, 2, and 3 had no pop so except for higher rpms since my tach doesn't work I have to assume around 4-5k. Stripped that side of the harness, ran it along the firewall and rewrapped it replace all the connectors and injectors due to corrosion and brittleness, and replaced the ecu as well. Now I'm getting no start at all, power to the drop resistors, ecu, and coil. The timing seems to be working properly however I'm going to be going back over everything I've done on the harness after I use the original ecu to test it. I may have missed something when I was rewiring the harness. I updated all the components using 94 villager relay and fusible links, and a 91 sunbirds fusebox. I'll be posting again sometime tomorrow.
