This group successfully solved the mystery as to why I could hear my injectors inside the cab of the truck (a fuel line was sitting against the seam of the cab). now I'm hoping you can help me with another issue:
the last time I was home, I backed the truck out of the shop (after looking and looking and looking for this noise). after about an hour I went to move it, and it wouldn't start. 3 hours later, it fired right up? my truck has been the most reliable vehicle on the road in the 12 years I've had it, but then this last April it broke down on a cross-state trip. turned out to be the ICM. a month later, broke down again and turned out to be the pick-up coil. a month later, intermittent injector problems so I replaced both injectors and the ECM (with a gasket set for the TBI including a diaphram for the regulator).
any ideas on this last issue? you guys nailed the first problem!
thanks.
