'99 7.3L intermitten no start

[BustedKnucklez]

I have this side job for a friend of a friend that intermittenly wont start. He says that he notices that this happens when his "wait to start" light doesn't turn on when he cycles the key on. I got a p0403. He told me he disconnected the batteries trying to get it to start. Any ideas?

Unplug the ebp sensor when it is a no start - do you get the wait to start light back? They used to short to vref and cause no start.

If there is a chip on the PCM it might have a poor connection to the board. Can happen if the clear sealant was not properly cleaned off or if the chip was not taped in place it can loosen the connection of the pins. No WTS light = no startie.
