with the oxygen sensor unplugged it still ran for about 5 minutes and
stalled.  the fuel pressure is right where it is supposed to be, according to
the gauge.  The temp. sensors are new.  i will have my friend who is doing
the work on it check the valves but they are not rapping.  i ordered a new
oxygen sensor anyway because it can't hurt to have a new one.  i now think
that maybe the sensors is at fault(?) but i would like to pass the info on to
him as to what has to be done to check the proper reading of the temp sensor.
 Most of the good people on the list have said it is the temp ll sensor.  i
will check it out in the near future and forward the results.

Thanks,
