SOURCE: 2002 Jeep Liberty Prolonged Cranking problem

Fuel pump: The engine may crank several seconds before starting due to loss of fuel pressure caused by a bad check valve in the fuel pump assembly. (2002 models)

Have you tried replacing the starter? I know starters can go bad if the car is not started or run for a long time.

I am getting the same car, with the same issue.. it sat for 2 yrs and won't start.

My mechanic told me it is probably a starter.

Do you have the "firing order" correct? In other words, is each spark plug wire going to the same cylinder it was on before you changed the plugs? If you have done nothing else but changed the plugs then this is the most likely problem.
If when you try to start the car it backfires through the exhaust or backfires through the intake. Then this " IS" the problem. Good luck.

This def sounds like a fule pump issue ...it should be located in the gas tank its self although i would check the fuses first before getting into the tank.
If this is in a 240sx the way into the tank is through the trunk.Lift the carpet and you will see on the mid right side a small 6-8" lid with some wires going into it. Unscrew that and your on your way in.
If you do pull out the pump just be careful handling it as to not break the sensor unit attached to the pump.

I just had the same problem with my '02 altima SE.
Took it to Buckeye Nissan in Hilliard OH. and they had to replace the two crank sensors which.
The sensors themselves were about $44.00 a piece, but w/labor about $300.00 was the total. Hope this helps.....Now if I can just get the heater working!
