Timing Belt Conundrum
 

I figured with everything going on and since I'm working from home now would be a great time to do some maintenance and change my timing belt, WP, etc.
I followed Tim's instruction video (Thank you very much) and it went surprisingly well, other than the tensioner bolts being rounded and having to take the whole A/C compressor off to get to them.
Once back together, I went to start it and it cranked up and then immediately died. I tried giving it some gas, and still only ran for a few seconds and died. Waited a day, came back and same results.
*Full disclosure, I made the mistake of trying to change other stuff while I had it all apart. I cleaned the throttle body, changed IAC valve and gasket (reverted back to old IAC, and changed coolant temp sensor.

I stripped it down to check timing again and everything still lines up.
I did a little cleaning while in there with some compressed and paper towels but only sprayed throttle body with any cleaner.

I would really appreciate any input and things to check or test and see what I could have screwed up. I've read through other threads and checked all connections to make sure they're in-tact, but can't find anything wrong.

Check the big 3: Fuel, air, spark.

Did you disable the fuel pump during the procedures?

Spark is easy enough to check.

I suspect something not put back together correctly with the TB.

Thanks for the quick reply. I have those since it is starting and running, just not well. I wonder if I could have screwed something up when I took the throttle body off and cleaned it, but I think it would have dried out and would run by now.
Could the mixture be out of whack? When I tried running it, and repeatedly cranking it, it smelled strongly of gas afterwards.

Did you remember to reconnect the cam position sensor?

Did you double check all vacuum lines are properly connected?

Why did you replace the IAC and then go back to the old one?

Double check your cam, crank and maf sensors conections. Make sure they are secure and tight when trying to start the engine.

Always double check this....so easy to mess up.

Pull one of the plugs and see if it smells like gas. Sounds as if there is no fire.

Did you change the crank seal?

Ahh, I read that it ran for a few seconds then died. Agreed that the fuel smell points towards IGN.

Yes I checked the cam and crank sensors to make sure they were plugged in good and tight. Could coolant spilling on the crank sensor plug cause it to short? When I replaced the thermostat some coolant poured out onto the plug.

I reviewed my vacuum diagram before starting it to make sure all the hoses were on.

I had a high idle thing going on and bought a remaned IAC off ebay to try and fix it. When I plugged it in the connection wasn't great, and the lack of any part number made me think I got cheated, so I immediately put the old IAC back on. But that was after trying to start it.

Thanks. I found that to be a common issue when searching, but I made sure all were plugged in good and tight before starting it.

Thanks for replying.
I didn't remove the plugs or wires. They are still in good shape, only about 1.5 years old.

I did not change the seals. I was going to, but they looked fine and weren't leaking, so I didn't mess with them.

I'll try pulling a plug and see what I find. It does run upon cranking it, but then stalls and dies.

If you have fire, plugs aren’t gas wet, and you can manually turn over the engine at the crank and all the marks line up every time, consider that it may be a problem that occurred when you took to cleaning the IAC. Vacuum line not hooked up, ete.

The picture you provided were bit unclear did the cam and crankshaft marks line up correctly after hand spinning the cranksaft?:keyboard:

Coolant temp sensor OEM?
