Kiaracer--I sent you a PM

Kiaracer,

It seems my description is lacking.
Both of the timing belt cam sprockets are totally the same in all makings etc., but they have a slotted hole that the cam bolt goes in the center of. Since that slot goes equally out from the cam bolt it allows them to be installed on the cam pin in 2 different ways. That means that one (or even both) of the sprockets could be 180 off of it's original position. Will that make any difference in the timing? Or is it that the cam will give the exact same lift order if it's sprocket is on 180 from original? It doesn't look so???
Again i don't know of the relevance to their question but can it be a possibility effecting firing?
How would you determine the correct possition on each one?

i see what you're saying now and yes it would throw the timing off by 180 degrees. i've never had the cam pulleys off of the cams on a sportage so i'm not too sure how you would tell. i've never had a good look at them to tell either. any time i've had cams out, i've left the belt pulleys on them. unless they've had the pulleys off of the cams i doubt that would be the issue with their problems but you gave me something to look into that would be a good thing to know especially if the problem ever came up. i'll be sure to post what i find when i find it out.

How in the world do you accomplish this with that stupid tin plate for the belt cover between the sprockets/pulleys and the head?

I haven't checked but i think that if both the sprockets are installed 180 off it might make it come back into time??? One of them off seems to be a big error. tomorrow i have to put mine back on. I will diliberately turn both to 180 off and turn the engine by hand to see how that effects relation to TDC. I did notice that it really doesnt matter which is I or E as long as you have one of each when installing the belt. One is TDC intake and the other TDC ehaust no mater which you start with. I want to turn this crank by hand at all max valve openings any way to insure that there is still no piston interference.

When you only have 4 cylinders it gets less complicated but more confusing???

I wonder if i have a big enough shoehorn to get a pontiac 400 in there...LOL
These same cam issues, and starter location, are why i hate ZR-1 (LT-5)and Northstar.

alright i did some studying and from what i can see the dowel pin in the end of the each cam (not counting the dowel pin in the end of the exhaust cam for the cam sensor) should be pointing to the letter on the pulley that the came is used for. the dowel pin on the intake cam should be in the hole in the pulley closest to the "I" and the dowel pin in the exhaust cam should be in the hole in the pulley closest to the "E". this is what the picture of the ends of the cams looks like on KGIS:

in other words, turn the cams so the dowel pins are at the TDC position and put the pulleys on just as you would if you were lining up the cams to set them at TDC, put the bolts in and tighten them down.

Un-plug your relays under the hood I have a 1999 there are two 1 EGI 1 Fuel Pump relay they are both the same switch them check where they plug in for corrosion ( slam them flat on a table to on stick the internal reeds (perhaps frozen) when you plug them in hold your hand under the block then firmly plug in. This fixed the problem completely(I was thinking faulty Electric fuel pump or computer not sending a signal). Good luck, Van...

Hello again and thanks for all the info guys.Here is the latest info.Cam timing is perfect But the car will still not start!!!!!!.Hooked up fuel pressure gauge and fuel pressure is fine but discovered that when i swing the car and leave it on ignition fuel pressure drops to zero bar???.After further investigating by unplugging injector harness to no 1 injector.Fuel pressure does not drop ,somehow the computer in giving a constant earth to inj 1 and when i switch the car off there is no "earth" on the injector plug so there is defnitely no short in the wiring.
Will try and get hold of another computer box.

if it was getting a constant ground the injector would be open the whole time and it would be dumping fuel into cylinder one which means fuel pressure would drop. ground to the injectors is being controlled by the ecu. the injectors are getting a constant +12V to them from the fuse box under the hood. if an injector isn't opening it's either a broken wire, bad ecu, corroded connector, or possibly a bad injector.
