The GTS 4AGE never came with a start under the intake. You my want to look at a 4A-C engine.

Re: 4AGE 16V Bluetop HIGH IDLE
If you end up removing the valve for testing, then try cleaning the valve with carb/choke cleaner. Some times the valve gets gummed up, and the carb cleaner will free up the valve. As Jondee86 mentioned, verify you have water flow "to" and "from" the valve. If all else fails, you...

Re: Bike carb conversion: Gas pedal travel issue
Take totta crolla's idea one more step. Make the throttle pedal arm adjustable. I used the cable eye end from the stock pedal, and threaded it into a lower tube section. You can then thread the arm length up or down, to the vary the leverage i.e. travel. Once you get the correct length lock it down ...

Re: Crank no start after warmed up
Does the engine just stops while warming up, and then difficult to start? You need to narrow down the problem to either fuel supply or injector signal. Try spraying Quick Start thru the FPR vacuum port to see if it will start right after warm up/stop. You can also try jumping the electrical fuel pum...

Re: 4AGZE Injectors Not Firing
The grounding location on the intake manifold is common for all 4 of the injectors. If its a good ground for 2 injectors, it should be OK for the other 2 injectors. It is must likely a bad plug pin or wire. You are going to have to check each wire run to find the problem.

The odds are low, but the problem could actually be the crimp in jondee86's photo or pin/plug connectors.

Since you have the red-black wire striped back to the tee connection, Use a VOM [preferred] or continuity lite with a long test lead and verify that the red wire with the black trace, that runs to the ECU plug is good. There could be a break or enough resistance to screw up the engine ECU. You may w...

The electrical signal to the injector is so short that most VOMs will not register the signal. Go to you local auto parts and ask for a noid light. They are only a few bucks, and will verify the injector signal. davew7

Re: 4AGZE N/A conversion/differences between 4AGE and 4AGZE
Your plan sounds like a reasonable build. The only thing not mentioned was your ignition system. You will need a stand alone ignition system that will handle higher revs then a stock big port ECU. You will just need a few $$$ for your budget. davew7

Re: Hesitation at low rpms
The TPS is a good possibility, but it would not explain the difference you see between a hot and cold engine. The cold engine needs more fuel, i.e. the green sensor, tells the ECU that more fuel is needed but the fuel pressure is not there to deliver it. DaveW7

You need a richer mixture at throttle tip in. That 30+ year old fuel pump does not have enough pressure to enrich the mixture enough. Pull the fuel line at the filter and verify "deadhead" the line into a pressure gauge. You need a PSI reading in the mid 40's to get a regulated PSI in the ...

Rick Did you replace the ignition coil with a stock Toyota coil or did you find a replacement coil with about the same primary resistance. I've been thinking about replacing my 30+ yr old coil, with something that will fire a .040-.044" plug gap.

Re: More issues...engine intermittently stumbles under load.
The best method for checking pressure is verifying the pressure with and without the vacuum line attached to the PR. 30 PSI fuel pressure is not going to cut it even with vacuum line attached! You really need higher pressure in the 34-35psi at a min with the vacuum attached. For accelerating you nee...

Re: More issues...engine intermittently stumbles under load.
The input side of the fuel filter is 1/4" NPT, just thread in a pressure gauge there. Min should be around 40 PSI.

Two probable causes, You do not have enough fuel pressure or the TPS functioning. Put a pressure gauge in the fuel line from the pump. The easiest spot is in front of the in-line filter. At a min you need 38-40 PSI. If it below the 38PSI get a new pump and strainer. Check out Rock Auto for a good pr...

Re: Timing woes and tps'
With all those issues, it sounds more and more like your timing belt may have jumped a tooth. How old is the belt? I would remove the front cam belt covers and verify that the cams are set correctly. You probably need to adjust belt tension or replace the belt.
