1992 4runner sucking the life out of me!!!! Please help!!!!!
      07/05/07 10:14 PM

I am working on a 1992 4runner that my father and i purchased a few months ago. When we bought the truck, we knew it had a blown head gasket. We had the heads reworked and pressure tested by a local machine shop and put the beast back together. when i tried to start it for the first time it fired up and immediately went dead. I started by checking timing first, then checked the fuel circuit. That is when i found that my injectors are not pulsing.(I determined this by using a noid light) From that point i starting chasing the ground circuit. I can manually ground the injector pin on the ecm and make the injectors pulse well enough for the vehicle run. I then replaced the ecm, and it does the same thing!!!! I have checked every ground that i could find and they all seem to be good. I also replaced the air flow meter and still nothing. I have checked the efi relay and fuse and they are working properly as well. I am thinking that the distributor is the last link. If anyone knows anything or has had a similar problem please help! Thank you for reading this, sorry for being so long winded!
