Computer problem
1990 Toyota Pickup 6 cyl Four Wheel Drive Manual

So i baught a truck that wasnt running, and there is a 4-runner engine in it and the mechanic got it going but then it quit. so i baught a new ECU computer thinking thats what it was and still nothing. and when i plugged in the ECU i turned the key and the flashers went on at a rapid paced and the headlights turned on. what else could cause the truck not to work if the computer isnt the problem. please just give me idea of what it can be. im thinking maybe a bad connection..
