What is the firing order on a 1987 dodge ram50?

I don't have a diagram for you...sorry but maybe I can explain it to you. Here we go, Take your number 1 spark plug out. That will be the front one. Make sure your coil is disconnected and have someone just breifly turn the key on and off. enough just to turn the engine over a little bit (tap it). Continue having them "tap" the engine until the piston in that cylinder comes to the very top. You can stick a screwdriver in there to feel if it's at the top but don't leave it in there as it may jam in there as the piston comes up and could cause damage. Now when you get that piston to the top of the cylinder you should be at top dead center (TDC). Look and see which post the rotor is pointing to as if the distributer cap was on. The one it is pointing at is the one the number one plug wire goes to. The firing order is 1 - 3 - 4 - 2 moving in a clockwise rotation. I hope this helps you and you may have already known how to get it to TDC and so forth, I just wanted to be sure. Your truck came with 2 different size engines for that year. a 2.0 and a 2.6 but both are the same as far as this procedure and fring order goes. Good luck.
