Slow Start

[1gentalonfan]

Ok this isnt really a problem i was just wondering on this but when i start my car i always have to crank it for a few seconds and i was wondering how to get it to start right away like all the otehr cars ive driven. i replaced the plugs and wires today and thought it would help but it didnt. ive also replaced the intake filter nothing so far has helped. could it be that there isnt enough fuel pressure there right away, ive been told that might be the case and that if i leave the key sit on for a little bit before starting it might build up pressure. is this true? also the plug from piston 2 was completely covered in oil like gunk, is this because it wasnt properly tightened before or could that have seeped down there when it was refilled with oil, because under the little plastic piece where the wires go down there was some water/oil sitting there off to the sides.

could just be an older battery causing it to crank slower?

nope just replaced the battery about 3 weeks ago

Check your gas cap for no air leaks seal (replace gasket?). When you turn off engine (after running awhile) you should hear air rushing in when you open gas cap. Also check your FPR to hold pressure (for hours) after turning engine off.

how do i do that i didnt even know these came with FPRs i thought it was just the pump would only go so far as to not bring in too much fuel.

You may be right. My book doesn't show a FPR for a 1g NT. I was looking in the wrong section. However the guy in this thread claims they do: http://www.dsmtuners.com/forums/showthread.php?t=199947. You may want to look as he talks about low FP and where the FPR is (that's where it is on my 2g turbo but you can look at your engine and tell us if a 1g NT really has one or if he just made an invalid assumption). A clogged fuel filter and fuel pump are listed as possibilities of low fuel pressure. You can try holding the key to on for a few seconds before cranking but I know on the 2g the fuel pump doesn't run until you crank so 1g may be the same.

ok, so i looked at where there is supposed to be the fpr and there is something there that looks kinda like the oil pressure sending unit but a little smaller, it had 2 hoses on it like it said one went towards teh tank/pump, and the otehr went under the intake manifold somewhere i didnt follow it very far. could this be a fpr and if so would replacing it help my car start better

Yes that sounds like it is the FPR. Replacing it may help the car start better if that is the problem. Unless you actually measure the pressure at the fuel rail when you turn the engine off, you won't know if it is. Unfortunately you may just have to replace it to see. Keep in mind there are dozens of other things that may be the problem like injectors, vacuum leaks, etc.
