If you can make it blink by plugging and unplugging the flasher module, and everything else is OK, then I would blame the flasher module. I've heard of people installing LED bulb resistors, to simulate the load of a regular filament bulb. That could be a solution, and then you could use whatever flasher module you want. Steeveedee mentions above just leaving regular incandescent bulbs in the front parking lights, that may be an option too. I can't think of much advantage of LEDs in front. LEDs in back are advantageous because they give your brake lights instant on.
