Hi all:
I bought my microsquirt last year. When it was delivered I immediately set it up on bench hooked it up and began configuring the basic parameters to suit my needs. With out a hitch. So over the year I have been doing other things to the vehicle and now I'm ready to start it up but nothing works. I get power to the unit (even checked to see 5VDC at the voltage regulator. It was there.) I can't communicate with it, there is no fuel pump, no ignition, nothing. I've been trying to figure this out now for 3 days and have solved nothing. Any suggestions any one???

Is the
boot loader lead grounded?

I would do that if I were trying to load software. I just want it to run with the software it already has.

If you bring it back to the bench, does it work ? Or did you mean it now doesn't work on the bench and you were getting ready to put it in the car ?
If it doesn't work on the bench, then try nto think what was the last thing you did on the bench before it quit. If nothing jumps out, try reloading code.
If it just doesn't work on the car, but works on the bench, make sure you aren't powering your laptop with a power converter that works off the car battery.
Does it communicate with the engine off or do you just lose comm when you crank?

Did you check the comm port your computer designated for the usb adapter? And set tunerstudio/megatune for that port and tested it?
No pump is usually bootloader grounded. I think it cycles the pump if ecm type is not set?
