Re: WTB AW11 U-joint (manual rack)

There is a high probability that they have the right spline count in stock. They had a Toyota to English rack U-joint in stock that I needed. I got my U-joint from Sweet but both suppliers have excellent quality. Davew7

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.

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

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...

The input side of the fuel filter is 1/4" NPT, just thread in a pressure gauge there. Min should be around 40 PSI.

Re: Hesitation @ lower rpm

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...
