Hey out there sorry about my other post on "Oh now what" it is vague. A few days of research and tinkering and I am down to something is making my ASD relay cycle. This means everything is powering on and then off again in a flash. If I leave the fuel pump relay and fuse in it fills my cylinders with fuel causing hydro-lock. I have un-plugged and re-plugged every sensor I can think of, and I un-hooked the coil. The only thing I have not done is replace the computer. I can try one out of a 2000 but it is different I think. I have a 99 with the 5.2 the 2000 has the 4.7. I can't even hook it to a scanner because it turns the scanner on and off as well. Any help would be much appreciated I am at a loss, out of ideas, and burned from wracking my brain!!
