Possible causes:
1. No or low coolant flow
2. Hoses not routed correctly so that the coolant never gets to the radiator
3. Massive air in the system
4. Running very lean
4. Blown head gasket from boiling over previously

1. No or low coolant flow <<< Most like the case due to a weak signal to the electric water pump.
2. Hoses not routed correctly so that the coolant never gets to the radiator <<<< Hopefully not, moved messing with the water put hoses but I labeled everything before removing it.
3. Massive air in the system <<<< could be an issue but I put the nose to the ground and the rear about 2 feet higher and used a no spill funnel.
4. Running very lean <<< running on an electric water pump but I did just replace the MSD optispark so this could be the case.
4. Blown head gasket from boiling over previously <<<< I hope not....

Don't go chasing ghosts dude, wait for the controller and install it. Just make sure to follow the instructions that come with the controller. Upstream or downstream, the controller can do either way. And use the best program for your project. Any questions let me know.
One thing, make sure you mount the pump as low as possible compared to the engine and radiator.

Take your thermostat out and choose a program to run the pump without thermostat. The controller will pulse mimicking a thermostat. Take your time and read the manual, its very helpful!

OK La Fiera, I got my TinyCWA today,

Questions:

1. Where did you tap into to install the provided Bosch temperature sensor?
2. Where did you tap for the cooling fan?
3. Where did you tap for the ignition 12V on?

I may put the controller on a 12V toggle switch vs. ignition. This would give me the option to cool the car down with the engine and ignition off.
Do you recommend this?

1- I installed it on the head because it is the where the temperature is the highest in the 60*V6 iron head. Tecomotive recomends installing it at the hotter spot.
2- I tapped the stock fan relay. Cut the wire that suplies the ground from the stock fan switch. Or you can use a regular relay and pigtail.
3- Since I don't have windows I use that circuit because it is on when ignition is on.

Anything else let me know.

No, let the Tinythingy do its thing. The controller will cool the car after shut off if the motor is withing the range of temperature you choose, but it will do it slower. it's part of the programing of the controller. If you want to cooler faster just open the ignition switch.

Need a little clarification on the fan wire.

On the Fiero side; CUT the Green\White off the FAN rely , CONNECT to the blue wire on the TinyCWA side?

Once you got it all wired up you can test it without starting the engine. If I remember correctly the system is programmed that if the temp sensor fails the pump and fan are full on. So, when you are done wiring just unplug the temp sensor and fan and pump should be running.
You can also bleed the system without starting the engine.

La Fiera ,

I can't get the pump to flow throughout the system. I tested the TinyCWA and put the dial on position #3 TEST MODE >> PUMP to 100% and Fan ON. I would assume, I would be able to squeeze the hoses and feel the flow. I don't feel anything.
I can hear the pump running. The rear of the car is in the air about 20" to ensure no air blocks. I also burped the system using a no spill funnel.

I don't know what I am doing wrong.

Where is the pump located?
If you use the thermostat there are specific settings to use.

I don't use the thermostat and run it with its corresponding setting and the pump is the lowest point in the cooling system.

Where is the pump located? It's up front , next to and below the shock used on the steering rack. <See pics on page 2 > It sits about 1-2 inches lower than the lowest part of the front bumper and below the lowest point on the radiator.
I removed the propeller from stock water pumps and don't use a thermostat.

When your pump is on; do you feel water pumping thru the top hose on the radiator?

Hello All,

With the help from La Fiera, I was able to get the pump working. Turns out I had a trap between the radiator and the water pump. Similar to would you find on your sinks and toilet; the S Bend. So I was not supplying the pump with water.
I re did the inlet to ensure a drop and leveled the hose ensuring no upward bend. Ran the car for over 30 minutes, in test mode 3 , using the TinyCWA (100% pump \ Fan ON) keep the care below 160 Degrees. I still need to install the temp sensor that came with the kit.
La Fiera... I can't thank you enough sir.

My pleasure Sir! We should make a "How to page" on this upgrade for others to benefit.
