I have an obd2 car that i just did a obd1 motor swap in.. everything is all set but when i try to start the car it just cranks and wont start. I checked for spark and i have it. The car starts on fuel in spray bottle. Im assuming i have no injector pulse.. why?? can anyone help me.. i already put obd2 intake manifold with injectors on. all other sensors with the exceptions of crank sensor due to no spot for it. PLEASE HELP ME ASAP...
