Thaks for all your good advise!! I really appreciate your patience with me..One last Question..So if i didnt mark the harmonic balacer..It has to go to the far left? Is there a mark on there to help me with that? Does it just slide over the tab inside the cover when I do that? If so it should be pretty easy to tell when its on there right? If it does not fit on a tab..What makes that throw everything off? thanks again for your help...

I had a problem like that with my pathfinder..It started getting worse where it died more often..Even when driving..I turned on my truck..Kept the radio on with the windows open and began moving the wires that went into the positive on my battery..Sure enough one of them that came into the positive was loose..I pulled the wire out of the clip, cut the wire back a bit and exposed more of the wire eposing a new part of the wire,and made it snug in the clip..Never had a problem since..Maybe this could be your issue also..good luck man..I know its annoying..

Thanks for your help..My first problem might be that its too tight..I thought the tighter the better so it wouldn't skip a tooth..And my friend thought with it being tighter it might help the performance..Sounds like not so much..With it being too tight would that make it run poorly and shift at a higher rpm because of the strain of the belt being too tight? Also I marked the top two wheels, and the bottom crank..When i took the timing belt off i heard the gears dropping,shifting, when they moved..But it looked like the crank on the bottom didn't move at all..Is this normal? Or could it be it spun a 360 on me? also when i look for the tdc..I do this with the belt on correct? with a wrench on the crank? and just doing that I will feel air coming through the # 1 spark plug? If its off a couple teeth do i get one at tdc and then count off the teeth to get it right? Sorry for all of these questions..When my roommate and I did it the first time there were no problems like this when we marked everything..Quess i must not have noticed one of the wheels turning more than I thought..Or belt too tight..With the Harmonic balancer pulley..Does it only fit on there one way on a notch? Or does it just go on there and tighten the bolt..Sorry for all the questions..Last time I had help and it went smooth...Now my friend is kinda busy to help out..I parked it though so I dont mess up my truck till I get it right..Thanks alot for your help..this has been a huge learning process..

So I have a 93 pathfinder se 4wd..When it runs i love it..But within the last couple months I have had some problems and I am looking for some advice..Hope someone can help..First of all it had a weird noise that was kind of loud..I took it to a mechanic and he said it was the oil pump..My friend listened close to it and he didn't hear any noise coming from there..Is there any other way to trouble shoot if it is the oil pump? Also i changed the water pump thinking it was that because it had a weird noise when i spun it by hand..Well with changing that I had to take the timing belt off..When i did this i marked the wheels and bottom crank shaft, i guess its called where the harmonic balancer sits on..Both top wheels moved slightly but the bottom one did not..After changing the water pump I put the two wheels where they went by the marks I had..Now the truck runs pretty bad..It shifts at like 3000 rpm's or a little higher and it does not have that much power when I press on the accelerator..Not at all like it had before..One of my friends mentioned it sounds like i didn't match up the harmonic balancer pulley over the tab..and Its not sitting on there correctly..Would this cause the power problem..I changed the water pump once before and put it back together and everything was ok..But I did have a friends help that time..or could this be because the bolt was not tight enough? It does seem to vibrate a little..Just looking for some advise..I have taken it apart more than a couple times and am just a little frustrated now..Also, I read a earlier question and saw you could use a chain wrench..It worked taking off..But broke the second time I took it off..So I know I sound unexperienced with this,but I am so close and dont want to have to get rid of my pathfinder..Any advise would be greatly appreciated..Thanks..
