hi i just rebuilt by original engine in my 91 mustang that had about 130k on it. I upgraded it of course with edelbrock performer heads and intake, anderson b-21 cam, 1.7rr 42 # injectors vortech v-1 s trim. throtle body ext ext, (bolt ons)
i dropped it back in the car wired it back up and i get nothing. i put my key in the ignition, i get power to lights and dash. but when i turn the key i dont here the fuel pump purging, neither does the car crank. what may i have possibly forgotten.
can anyone list the power and ground points and/or any use full info. ive been working on the car for about 2 months and just cant wait to see it back at wot! lol
