I posted this question yesterday and hope for more suggestions today. I have a 1997 9000 CSE manual trans. Several months ago I noticed the cranking time became noticeably longer before the engine started. I would guess a cold start takes about a three to four-thousand count, where before about a two count. I have a strong battery, new plugs and new engine intake air filter.I've noticed that if the ignition is turned to ON when the engine has been off for more than twenty minutes, the instrument lights come on and about two seconds later the fuel gauge will initiate to show fuel level. The fuel pump can be heard and continues to Run regardless of how long you leave the ignition in the ON position. However, if you turn the ignition to Off after three or four seconds and then back to ON position, the pump does not restart. I'm assuming my fuel system loses its static pressure after engine is off for more than twenty minutes. Is the fuel system designed to remain under pressure? How long? Is it under pressure from the pump to the injectors or just from the fuel regulator on the fuel rail to the injectors? The slow starting seems to be related to not having fuel for the first few seconds of cranking?
