Hi, I’m new to this forum. I found ETCG on yt, great videos BTW. I have searched many forums trying to figure out my no start condition. Here are the symptoms. One month ago it started having issues starting. When cold It would crank and start but run rough and after a few minutes run perfectly. When warm no problem. Now it won’t start at all, it will try to fire when it starts cranking than just cranks with no sign of ignition. Here are the things that have been attempted or things I think I have eliminated.
New timing belt, tensioner, water pump etc. 40k miles ago (mechanical timing is good)
New ignition harness 20k miles ago, worked fine no dieing.
Has noise coming from the fuel pump when key turned on, smell gas when trying to start, no visible leaks. I have not check the fuel pressure, not sure how on the TL.
Tried the main relay no change.
The immobilizer is working correctly (flashes a couple times and goes out), no after market security stuff.It appears to me to be a timing related problem as I don’t think it has a bad fuel pump and it does have spark. The car ran perfectly a month ago after warm up, no misses, smooth and great power. Unfortunately I disconnected the battery before I installed the main relay and I have no codes I can provide.
Any help would be greatly appreciated??? Maybe a crank sensor?

New update!!! 1999 Acura TL 197Kmiles. Starting problem.
I cleaned the EGR port per the ETCG video. The port was all clogged up with hard carbon, what a mess!!! No dealer installed sleeve like the video.
I cleaned the idle control valve. It was a mess.
Replaced the original spark plugs, yes original confirmed by NGK.
Replaced the main relay with OE part, it had an after market one installed.
Replaced the battery. I was jumping the car to try to start it anyway. Free replacement from Autozone I have other cars that use the same battery and that one was 4 years old lol.
I cleaned the throttle body really well.
I replaced all of the original gaskets I removed with OE replacements, only $27.00 including the plenum.
The results: The car fired after about five cycles of the ignition. It idled around 1200 rpm initially before settling to around 750 rpm. The idle is smooth and consistent.
After warm up it starts easily. If I let it cool down it is harder to start. I let it cool down completely and cycled the ignition/fuel pump three times before trying to start and it started easily???
The car runs great!!! Smooth with plenty power no misses, no sign of anything once warm and running.
I was throwing a P1607 before all of the changes and after over an hour of running and driving, no new codes. I’m hopeful the P1607 will stay away.
I purchased a used fuel pump on ebay for $35.00 including shipping. I figure it is an easy swap and will take the fuel pump out of the equation.
I also had a problem with the power steering pump. It was making a ton of noise and leaking fluid from the reservoir cap. It was getting air in the system and I replaced an o-ring after watching the video below. It works perfectly now. Nice cheap fix
I will keep you posted on the results of the used fuel pump.
Cheers!!!
