i had this same exact problem id like to know how you fixed it.....i was always told to fix the cheapest part first so i did research and found out that one of the coolant temp sensors can cause your d4 light to flash and your car not to start,because its sending the wrong signals...replaced it the next day and it started up every time and my d4 light has never blinked again!i had this same exact problem id like to know how you fixed it.....i was always told to fix the cheapest part first so i did research and found out that one of the coolant temp sensors can cause your d4 light to flash and your car not to start,because its sending the wrong signals...replaced it the next day and it started up every time and my d4 light has never blinked again!

Might need to replace your transmission control module located under your pass side floor carpet. Remove the plastic kick panel to the right of the passenger's foot, carefully pull back as much carpet as you can. There you'll see the cage for the ECU and your trans control unit. The trans computer is the smaller one. Good luck.
i have a 92' honda accord lx, it has a problem of the D4 light flashing and the car wouldnt start, but i could wait a few minutes and try again and it would start.
you have a transmission fault the D4 light blinks to tell you that there is a transmission problem when the light is blinking the transmission computer put the transmission into limp home mode so it will not shift normally and you should try not to drive it very far when it gets to this stage you need to have the transmission codes check to pin point the problem
