[DeTomaso] Three steps forward, three steps back....

<<< by installing a mongo-sized fuel filter in line with the standard filter >>>
   
  1. Is the "standard filter" the old one that's had the debris tapped out onto the bench, or a new one?  
  2. And is it between the pump and the mongo-sized fuel filter, or between the mongo-sized fuel filter and the carb?
  3. Can you rev the engine when you got the 0-psi reading on the fuel pressure gauge?
  4. Do the symptoms show up only under load, or do they show up when revving the engine with the clutch in too?
   
  If your filters are new and the big one is between the pump and the standard filter, then lets 
  take a different approach...  It sounds like it could be spark related (although that doesn't 
  explain the 0-psi on the fuel pressure gauge, although at idle the pressure may be too 
  insignificant to register on the gauge). Maybe your coil or the ignition module is cutting out.
  Are you running an electronic ignition?  If so, which one? These items are often temperature 
  sensitive when they have problems. 
   
  I've heard you could try to lightly spritz some water (as in spray bottle to mist plants, etc) 
  onto the coil to see if the problem is magnified, but I've never tried this myself and make NO 
  REPRESENTATION about how safe it is for your ignition system. Do this at your own risk. 
  You could try swapping your ignition module and/or coil if you have spares. Or see if 
  someone else nearby has a known good module of the same kind that you could try before 
  spending $6-$100 for a new one.
   
  Cheers!
