Problem when starting

[rousie13]

When my car has been sitting for a day or so, and I go to start it, it doesn't want to start. It cranks forever, but won't fire. If i pump the gas a few times it will start but run rough for a few seconds. After this it runs fine and starts fine after that. I just put NGK Iridium plugs and Aurora wires on it. Any ideas on why it would do this, because I have no idea?

Come on people, someone has to have some idea.

I have the same problem. My car worked fine until I changed to the 300zx MAF. Then it has trouble starting when it is cold or been sitting for a while. I think I have a bad ground somewhere, or my MAF is dirty. Is your timing correct? If I figure my problem out I will let you know, I dont know if it is the same problem because I know mine has something to do with the MAF.

i had this prolem last week, i even bought a bew battery because of it, my problem was because of my batter cables, try cleaning all the acid on the end of the cables with sand paper until completely clean, then make sure your ground is good...hope this helps a lil...
