Finished tig welding all the exhaust componts at work and trial fitted on car. With this done I was able to throw some fuel in the tank and try starting the engine for the first time. Cranks with good spark but won' t run. Fuel pump is working but the cylinders are dry. Seams to be a problem with the injectors not firing . Drop a bit of fuel down the plugs and it fires into life. Having a bit of trouble working out the wiring on the circut opening relay. I have the wiring diagram for the miata engine but not being a auto electrician, found it a bit hard to get my head around. Otherwise making good progress.

If the fuel pump is running when cranking then the circuit opening relay should be ok, my thoughts would be the built in Mazda immobiliser?

Found the problem with the circuit opening relay. ( operates fuel pump) Needs to be a relay with two coils. One opened by the ignition switch and the other by the air flow meter. Picked up one off Trademe for $30. They are normally $150 new. Expensive relay! So finally got fuel flow into the cylinders. Also fitted an after market regulator with guage so I can check on fuel pressure as am using an out of tank fuel pump. I then noticed some fuel leaking around the injectors. Removed them and found the rubber seals were rock hard and were loose. Brought some on trademe, $2.50 each , cured the problem! At the same time gave the injectors a clean with carb cleaner, as per a video on You Tube. After all that the engine would fire but not keep running. Oh crap! Nothing to do but go over the wiring again, check the coil and hope it was'nt a computer problem. I then found a loose earth wire on the cam sensor. Those crimped on fittings rearly arn't that great and I plan to go over all mine and solder the wires on. Now I have a engine that starts and runs, woohoo!

Yesterday wrapped a board around the right side of the chassis and marked the dimensions for the outer panel. Hope to fold it this weekend. Also changed my mind about the vinyl I had covered the consol with. Removed it and recovered with the carbon fiber vinyl many use. A big improvement. Picked up some carbon looking mirrors from Trade-me to be mounted later. Needed to turn the car around in the garage to get more room and with the engine now running drove out, backed up and back in again. Careful that I only had a handbrake as the front brakes arnt hooked up yet.

Picked up my side panels today from the powder coaters. Almost a dayglow orange. Guards and scuttle will be white, which I'll probally spray myself , to break up the shockingly bright color.
