Over heated, no compression either bank. timing belt not broken 03 sorento

1. Remove the drive belt.
(Refer to Timing System - "Drive Belt") 2. Remove the A/C compressor.
(Refer to Heating, Ventilation, Air Conditioning - "Compressor") 3. Remove the A/C compressor bracket (A). 4. Drain the engine oil. 5. Remove the oil pan (A). Insert the blade of SST (09215-3C000) between the ladder frame and oil pan. Cut off applied sealer and remove the lower oil pan. • Insert the SST between the oil pan and the ladder frame by tapping it with a plastic hammer in the direction of arrow. • After tapping the SST with a plastic hammer along the direction of arrow around more than 2/3 edge of the oil pan, remove it from the ladder frame. • Do not turn over the SST abruptly without tapping. It be result in damage of the SST.

Who did the work? take it back. If it's DIY double check your work. Knoking as in metalic engine , or knocking as in gas preignition. If gas preignition, timing belt is off a few notches. If it's similar to this google: 2003 kia sorento interference engine
You may have valve timing off so much that your pistons are running into the valves. Bad news!

Test for spark at plugs, fuel pressure, compression, timing belt.

Caaarburetor? It's fuel injected, isn't it? Check the compression of your cylinders. If the timing is right, the engine just needs fuel, compression, and spark to start and run.

if the ignition and valve timing are ok. check out fuel pressure and flow. also do a compression test to make sure all is ok there.

If your sure the timing belt is correctly installed, then check compression. you very well may have bent some valves when the timing belt broke. low or no compression will be a sign that this is the case.

loss of compression: bad valve seating, bad valves, really bad timing, broken timing belt, bad rings...spark plug not tight. Bad spark plug wire, bad spark plug,.,.. etc., etc., etc.. Got some more details - say on how this came to be - engine size,. etc?
Best regards

P1131 -1. Misfire on bank 1
2. Vacuum leak affecting bank 1
3. Fuel injector problem bank 1

P1130 - 1. Fuel pressure high or low
2. MAP sensor dirty/defective
3. Vacuum leak on engine
4. Leaking fuel injector or fuel pressure regulator

Not much but what happened to the engine when it broke is a lot. Doesn't always destroy a motor but often bends and warps thing. The cost of the new timing belt should be the least of your worries.

The 2003 Kia Sorento with V6 has the spark plugs located under black plastic covers in the center channel of each cylinder head. Several brackets, cables, and hoses must be moved out of the way to access them. The manifold air intake tube needs to be removed on the right bank.
The left cylinder bank has coil-on-plug assemblies while the right bank has more conventional spark plug caps with sealing assemblies. The coil-packs are held with two 10mm bolts each and are difficult to get to. Use universal-joint sockets and an extension.
