Hi, I too am having the same issue with my 89 ranger 2.9. I have replaced the relay also and if I put power on the red wire that is coming from the eec relay to the wot cutout relayand then to the fuel pump relay, according to the schematicit closes the relay and the truck will start and run. The red wire should be hot with the ignition switch on, but mine is not. I do'nt know where the eec or the wot cutout relays are and auto zone shows these relays but they are not available.I need to know where these other 2 relays are so I can continue testing.Can anyone help me? All of my fuses are good and I have replaced the ecm , the ignition coil and the module along with 2 out of 3 relays that are under the fuse block on the pass fenderwall,and since the replacement relay from auto zone works in all 3 relays , I have rotated the 2 new relays thru all 3 positions to make sure the relay that I did'nt replace is good. The truck truck originally stalled on 2 different occasions, but started back up a while later and the last time it stalled it would not re-start.Has anyone changed the ignition key switch and solved this problem? I know someone has already suggested doing this ,but I think the guy just got rid of the truck.I really like my ranger and will continue to search for the problem,please respond if you have gone thru this. I also dropped the tank and put power to the pump and it works fine and the fuel filter is not restricted.I ran the truck for 10 minutes
with the relay powered closed as I stated earlier thinking that the new ecm might store a code ,but it did not.
