The engine is a 4 liter.The problem is very intermitant
so I cannot take it to a shop. The danged thing finally acted up at my
buddies house so he got to test it. He put
his timing light on it and the timing light did nothing. The
light did come on fine. Later my friend and I met up with a knowledgeable
mechanic friend of his who kindly
balanced his tires on a sunday. This mechanic suggested
several possibilities including a bad eec power relay. He also said I could
bring the truck by the shop and pay $75
to be told " It ain't doing it, I don't know." ;) Where is
this relay located? Any other theories? Thanks.

Could be the coolant temp sensor, or the ECC relay--however the ECC
relay problem usually occurs without any dependancy on engine temp. I'd
put my money on the coolant sensor.

Remember there's usually two of them, one that the computer uses and
one that has 1 wire coming from it that's used for your gauge in the
dash. You want to replace the one with multiple wires, the other
doesn't matter--it's only a sending unit, if it fails your gauge won't
work but it won't affect the way the engine runs.

Good luck, make sure you have teflon tape handy and are ready to plug
the hole quick because coolant is going to flood out all over.
