95 discovery 3.9 will not start. quit while driving at hwy speed. 40lbs pressure at fuel rail, strong spark, cranks. after sitting for a while it almost starts when first turning the key but then nothing. it seems that the injectors are not pulsing any suggestions

 

Try changing the fuel pump relay available at NAPA AR272 for like $12.79

Mine was doing the same thing and this seemed to cure it.... Or also check the connections at the coil and crimp them tighter so there is no play on the terminals
