On this lineup of products, 3 slow flashes after a failed start attempt means the module did not detect a tach signal. I would recommend you change your tach input to another location. Where do you have this wire connected to presently? You can take this wire at alot of locations in the vehicle. I usually go to the datalink/OBD II connector under the dash, but let us know where you took the signal from. Also, it should be un-necessary to change the Tach Threshold jumper on this vehicle. Good luck!

Which tach signal programming method are you using?  I generally use the autotach method on low threshold.  If you are having trouble, reset the module and start from scratch.  Also, are you pulling your tach signal from an injector or from the ECM?  I generally use the injectors and for the amount of ProStarts I install in a week (7-10 avg) I've yet to have an issue with tach signal being too weak.  It seems unlikely that 3 consecutive 3400TW's were duds.  The solution lies in slowing down and rechecking your wiring (I know it's tedious, but it will save you paying a tech like me min 1 hr labour charge to fix it).  If you need anything further feel free to message me.  I can help you out.
