If you have the spider fuel system, that system is noted for problems. Fuel pressure, key on engine off, 60--66 psi. Once it's started it will run with less pressure. In the past have seen service bulletin about fuel poppets sticking on a cold engine, usually after the first start up in the morning, it will run fine the rest of the day. The fix was a cleaning procedure, the procedure was a shop procedure.
