Turned over but no pop. tried many times. Windy day ~ couldn't smell gas! let set for several minutes ~ then it started but hard ~ had to crank it three times to get it going. Opened gas cap and listened when key was turned on, I could hear the pump run. Any suggestions.

This is a bit pf a custom car type lash up and untill you can get some local advice here dont use the car as the excess fuel will wash oil from the cylinder walls causing piston /and ring damage ,You need someone local who can sort out and re-map the fuel injection system for you just for starters,Nice try and do admire greatly your determination in making something work but as iam in spain iam not a lot of help on this matter also owing to europeon vehicle law i wouldnt be allowed to do this for a rad vehicle as it detract from the certificate of homoglonation so a non standard vehicle just isnt allowed ,cannot even change the back lights for a fancy one let alone a engine
There are several things which come to mind. You have 2 complaints. A gas smell and a cold blooded vehicle.
Starting with the temperature problem. My initial concern is whether the thermostat is weak, but also that the automatic controls may be inoperable and working against you. The car is suppose to go into a temporary "cold start routine" which increases the RPM and makes the fuel rich. (This could contribute to the gas smell)
After the Temperature sensor and O2 sensors warm up, the idle is suppose to drop and the fuel mix should lean out. If the engine remains at high idle, the water pump will work faster with the engine spinning faster. Sometimes there is not a direct 1 to 1 ratio between the heat generated by the motor and the RPM versus the cooling produced. An idling engine may warm up faster than an engine running at higher RPM.
Another problem may be the Defroster setting. There are Thermal switches which are suppose to cut off the Electric Radiator cooling fans. When the Defroster is activated, some cars are built to spin the A/C compressor in the Winter. But the Electric Radiator cooling fans may also switch on as part of the A/C system. This would super cool the radiator at a time when you least want it. Check to see if the cooling fans are activating when the Defroster is turned on.
There can be 2 Temperature switches in your car. One would send the signal to kick out the "cold start routine" and the other would work the guages or indicator lights.
The O2 sensors can have heaters in them or they can just be slow. If you leave the engine idling like you do, they could foul out and be sluggish to warm up.
If running the Temperature at 80 degrees causes an additional 5 minutes of warm-up time, you may be better off setting it for say 72 and having it work sooner.
The thermal sensors are not that expensive. Work on a cold engine when changing them. Note what I said about your rich fuel mix contributing to the smell.
you may have a frozen fuel line. fuel not reaching engine. put some dry gas in it to displace moisture in fuel system. the reason why it quit when pushing pedal is, its starving for fuel. have a good day !!
A faulty Intake air temperature sensor can cause that. If it's faulty and supplying computer with a signal that says it's freezing cold, when its not, then it would cause it to dump excessive fuel, when it isn't necessary. Might be smart & cheaper, to run it in and have it scanned for codes, at an auto parts place, or trusted mechanic. With all these sensors that can cause similar symptoms, why gamble, have it scanned & know for sure.
