ok guys, heres the lay-out. Had my gp for 12 years now, rebuilt it twice. recently the rebuild has left me speechless and dollar -buttsore. Have replaced everything under the hood sensor and wiring wise. internally new timing chain and sprockets. Had injectors tested at a most reputable local phoenix speed and custom shop. I was sticking which i replaced. new fuel pump, replaced it a second time, fuel filter. cleaned the gas tank thoroughly. new alt. After everything said and done, i got a slow/ no-start condition. fuel pressure is only present at fuel rails sporadically. checked fp reg. no gas present or odor of gas. fuel pump relay checks out ok. only get 9 volts back at fuel pump. wiring checks out to both cpu and fp relay. usually after 3 to 4 long cranks , car will turn over and run, but only shortly and then sputter and die unless i keep my foot into the gas. help please
