Hi guys and thanks so far there`s a forum for anything!!

I have a Isuzu rodeo 1997 ,2.6L manual ..

I`m very happy with this car as toyota hilux should be.. but in the past two week every time the car begun to start very hard( I will go to the bottom line) I checked everithing :fuel lines, fuel purges valves, gas lines and relays, well until I turn the switch to the ACC position and heard that sound of the fuel pump working, anyhow the car started and I shut it down again and purge the gas line that goes to the injectors, switch back agian to ACC and no noise was heard .. my question is how hard will be to replace it ???? which ware house has it?and which one in the market is best?? I have a 8 years experience with air cooled engines so I`m familiar with this things..

Guys,people,fellas. thanksss a lot for your advise....
