Am I the only one?

Long story short..... I replaced the timing belt, water pump, and all the other usual items in a timing belt change. The truck ran great with no issues before the timing belt change.

I put everything back together, so I thought.

Symptoms: the truck turns over but I do not have a spark.

My internet search has not come up with any solutions.

Does anyone have an idea as to solving this sudden lack of spark stemming from the timing belt change? Or, does anyone one have any advice on where to search on the internet for the solution.

Thanks

Crank position sensor is what tells the ecm when to spark if it isn't sparking I would start there. Not necessarily a bad sensor but maybe the gap is off or its unplugged.
 
Ok, I will start there.

Also if the teeth on the crankshaft pulley isn't lined up with the sensor the ECM doesn't know where the engine is as far as TDC (top dead center) it won't fire either

Can you explain with more detail how it's supposed to line up or what I am looking for? I never moved the crank when I took the timing belt off or put it back on. Any more detail will help.

If you didn't move the crank, then your engine is most very likely out of time. All the timing marks have to be Top Dead Center (TDC) to be done right when the belt goes on. In the photo above, the pink mark on the crank lines up with an arrow on the block. As well, the cams have timing marks that line up with marks on the back plate. These then line up with the lines marked on the belt, you don't necessarily need the lines on the belt, but they sure do take guess out of the job.

Internet searches will get you in a mess of confusion, so use this. The FSM has detailed step by step instructions

Hope you get it figured out! I know when I did my timing belt I was praying pretty hard as I cranked it over the first time.
 
Thanks for the help. It looks like I did not have the TDC aligned between the camshafts and crank. I had the camshafts at TDC but not the crank. I have inconsistent lighting where I am working and my crank didn't have the paint mark to help identify TDC, so I had gone off another mark thinking it was TDC. I found the TDC on the crank and got everything lined up. I tested the resilience on the camshaft and crankshaft sensors and they are in good working order.
