'91 300e cranks but no spark at the coil
 

Hi everyone,
Have a '91 300e 3.0 with 98k miles. Noticed car began to misfire and once in awhile would get a really sluggish off the line in first gear (almost as if I wasn't pressing gas pedal at all). Again this happened very rarely but when it did occur, it would occur in 1st gear from a dead stop, then would shift and accelerate normal after that. Recently did new fuel filter and fuel line connection, followed by spark plugs, wires, cap and rotor. Shortly after the tune up, on the first drive, car smoothly and quietly dies while driving (didn't even notice until I went to hit gas pedal and noticed no acceleration and all dash lights on. Replaced ignition coil, swapped out crank sensors and ignition control module but still no spark at the coil. When cranking rpm needle jumps to about 500rpm. Checked for fuel by disconnecting the connection at CIS unit and it has fuel and fuel pump works.
I am stumped, anyone know what can be causing the no start?

Thanks!
Dino
