Finicky Starting

[Yellow Rose]

Last November, the car was idling not too well as I was rolling down the driveway at home. As I engaged into first gear on the street and let out on the clutch, the engine died. When I tried to start it, you could tell it was trying to fire, but it sounded as if the engine was getting flooded. (I thought it is impossible to flood an engine with electronic fuel injection?) I let it sit for about twenty minutes, as if to allow excess accumulated gasoline evaporate, and the engine fired right away.

It did it again this past Monday and again on Tuesday. It is as if I have to pay close attention when cranking the engine, so as to focus on the first instant the engine wants to fire, let off of the ignition key and give it a small blip on the throttle to ensure the throttle body valve opens to allow air in.

Is this "normal" or am I whacked out of my gord? The engine has 16k miles on it and is BBSC'ed. I think the supercharger is a moot point because cranking the engine clearly involves no boost. To those familiar with e Split Second controller, I ensured the all-important four cells at key-on have 13.8 in the fuel map.

I have the same problem but not to your extent. I have yet to have my car die on me. If I park my car at a incline or decline for a hour or more I have problems starting it. It will actually take about 2 try's before it turns. weird.....

by the way my car is completely stock and has bout 26,500 miles on it. Should i be worried?

I thought I saw this problem before so I did a quick search and *BAM* here it is: It sounds like the main relay is not allowing the fuel pump to function properly ---see Larry Bastanza's response...

Remember ther are a few possibilities for the problem discussed in that other thread. Do not learn the hard way, like, you know who.

I checked the other thread as well; however, I do not think my situation is related to the fuel pump and / or resistor for two reasons.

1.....I have removed my resistor permanently.

2.....At key-on and while cranking, my fuel pressure is a steady 53 PSI.
