The 04 lives again. Replaced the entire VREF circuit along with every pigtail attached to the engine and the ICP sensor. Hooked up the batteries and fired instantly. Let it warm up to operating temps, smoked the tires down the block and all is well........for at least........well till the next time I try to drive it.
Have no idea where the problem was at, found the ICP and EBP sensors had both had the pigtails replaced at some point. A little oil from the ICP so I replaced everything and all is well for now.
Good to hear you back on the road again.
Thanks for posting what you had to do for the fix,
