Fuel Inj question

87 Ranger 2.9 fuel injectors.
I just replaced my lower manifold gasket. I didn't disconnect the injectors from the fuel rail, but I did have to disconnect the electrical connectors to each injector. I have been troubleshooting all my EEC sensors, but my truck runs like it has an exhaust leak.
My question is...do my injectors get their electric pulses in order? ....Like the spark plugs?

No, it's speed density. So it actually pulses in a batches, left side and then right side. So you get a least 1 pulse on compression each time.
