Ok, here is my new gremlin! Car seems to deal with one only to inherit a few more. Was having issue with no fuel pump even with Link V3 box checked and simply wired straight from Fuel/mpi relay blk/blue wire and voila! Now I have fuel but NO SPARK! Have coil on plug set up wired this way. http://www.dsmtuners.com/forums/articles-electrical-wiring/290665-coil-plug-wiring-install-pics.htmlI also wired my transistor like this. Stock (2g) 8 pin connector wire colors: pin 1: blue-black (output to fire cyl 2,3 coil's primary) pin 2: brown-red (input from ECU to fire cyl 2,3) pin 3: black (ground) pin 4: white (tach output to ECU and gauge) pin 5: unused pin 6: larger black-white (+12V from ignition switch) pin 7: black-blue (input from ECU to fire cyl 1,4) pin 8: black-white (output to fire cyl 1,4 coil's primary but leaves coil as blue-red going to single pin "engine speed detection connector", then from there to pin 8 here as black-white) Why am I getting no spark with plug tester?? When I turn the cas by hand I know that would usually kick on fuel pump and create spark but now it doesn't do anything. ECU directly pin 88, 89 to cas white and yellow wire. Ground I soldered to ECU sensor ground out and 12+ to the Fuel pump mpi relay red wire. Ok community!! Hit me with suggestions!!

Correct it's 5 volts. 141/391 it states that the power supply for sensors is 5 volts

My bad Mike is correct, just confirmed it is 12 volts. FSM is a little confusing to read.

Ya you can test the cam and crank signal wires going to the ecu. Making sure they do something when spinning the cas.
If everything has power and injectors are not clicking and the plugs aren't firing when turning the cas, somethings up, do you still have the mpi wired up?, MPI still there. Grounded the PTU with custom bracket. Willing to try any suggestion. Wondering how to wire this directly so that I can eliminate other flaws if any...........
