98 Sportage won't start

[jenoes]

Well the problem with mi sporty is that after a timing belt change, it was running without problems for a couple of months then suddenly the main pulley came apart of the crank and broke the plastic covers on the timing belt it lost the woodruff key. replaced the key set everything accord the intructions for timing and adjustments , the engine circle freely without any obstacles, check the battery charged for four hours to a full charge. after all this, when i try to start the engine spins freely like there was no gas o power, afriend a mine tell me that i need to replace the head on the engine.

can you guys could give me any advice on how to troubleshoot this problem.

thanks

A little beyond my experience with Kia's, but since no one else has answered:

Are you sure the cam(s) were timed correctly when you replaced the belt? Was there any damage to the crank or pulley when it came off? Did the pulley hit anything electrical? Check spark and fuel pressure. Maybe it knocked a wire or 2 loose somewhere.

I would make certain the valve timing is correct and then do a compression test.

you point out that the engine spins/cranks freely with the starter motor, which makes me think that you have no compression.

After cranking it pull one of the spark plugs and it should be wet with fuel, if not then you have a fuel delivery problem.

Crank the engine with the pugs removed and connected to the coils and wires to confirm theres spark.

well today I took the day off to check my sporty, timing belt points checked ok, gas rmove a plug it was wet, test plugs for spark ok, tight everything back together, tested with a different ECU the engine turns freely and you could ear like internal backfire.

this the second timing belt did you guys tink is the engine head that went bad?

thanks for your info, I really like my truck, and I need this scond car.

Are you sure that the timing belt was not damaged ?

If you are certain you did the timing belt gear allignment correctly (see below in italics), then, at this point, you really need to get/borrow a compression tester (maybe $30 at AutoZone) and test each cylinder -- pop out all four plugs; then test each cylinder in turn.

The key is to confirm that all four readings are approximately the same (+/- 10%) -- the actual values don't matter so much, though I'm guessing that they should be somewhere between 135 and 150.

7. After installing the belt make sure your alignment marks are set, the "I" on the intake ( left cam ) at 12 o' clock and facing the small dent on the timing cover backing plate and the "E" on the exhaust ( right cam ) aligned the same way as well and your crank cog marking ( woodruff key ) aligned to 12 o' clock and facing the small notch on the front of the block immediately behind the crank cog. There is also, most times, a small plate on the back of the crank cog that has a beveled notch in it and should be aligned with the woodruff pin, the two parts ( cog and plate ) are one part and move together so if you align the woodruff key at 12 o' clock, the notch should be aligned as well. Now might be a good time to disconnect your battery to allow the cam sensor to reset, it may not be necessary but its better safe than sorry.
