You obviously don't know what you are doing. PLEASE seek help before you go any further, or you will do damage to your engine.
There are videos on YouTube for your engine, showing how the timing marks are placed on each cam gear, as well as the crank shaft sprocket. If you have all of those markings lined up correctly, and the timing belt is correctly placed on its routing around the gears, and there is the proper tension on the tensioner assembly, then you've done it correctly. Forget about the pistons. If the marks are all located correctly as I described, the pistons will be in the proper position as well.
I've added a PDF file from the factory service manual, showing the step by step timing belt replacement for the SOHC engine. Read it carefully 2 or 3 times before you try it. If you get the belt one tooth out anywhere in the process, the engine will not run correctly.
Get educated on this process and be sure you know what you're doing before you dive in. Get it wrong and you could be in for a lot of grief and expense. The job is a DIYer if you take the time to study it first, and then check to be sure you did it correctly before you crank the engine.
