The very first operation with my AFC-NEO was to program in the vehicles sensor set-up and options. The SAFC has the same initial setup requirement.
For the SAFC to function you must FIRST run through a few sensor selection parameters;
1 - Setting the sensor type and sensor number (MAF).
2 - Setting the number of cylinders.
3 - Checking the throttle sensor voltage.
4 - Setting the throttle sensor type.
5 - Learning the throttle opening.
6 - Correcting the knocking signal.
Only after this, should you see if the vehicle will start.
There should be a way to remove the SAFC from its wiring harness and jump the connections on the harness in a way to go back to factory engine management only if you want to see immeadiatly that it is the SAFC is the problem.
As my own rule of upgrades, one at a time… Do the fuel system first, then the fuel control. Get the car to run correctly in terms of fuel delivery (from idle to WOT), then add all extra components. The Areomotive sounds as though it is working, do you have a mechanics stethoscope to find out if the injectors are clicking?
If you are sure it is not what I mentioned above, it could be from the upgraded hardware. As of what I am reading, it could be the injectors need a new resistor pack, faulty MAF I/O, or other engine management anomaly.
I have personally experienced “no start” situations with a faulty MAF, although this could be from the SAFC’s initial settings being incorrect. Do you smell fuel when you try to start it?
You have quite a bit of modifications done, worst case scenario, just start a list of components and engine management systems that ARE functioning properly. Work your way to focus in on where the problem may lay.
