I just finished a swap from a 87 2.9L in to a 90 2.9L I Changed out all the sensors on the top 1/2 of the intake and TB to the 90 intake/TB, put the 90 alternator on it, Put the 90 fuel rail and injectors on it. But it just cranks. I left the 87 distributor on it (w/ 90 Cap and rotor). I am woundering if the TFI-IV (sensor on the back of the distributor) is different from the 90's? or what else could be the Problem??
 
I have checked spark which I have. My Fuel Pump is not powering up, I dont have power to my tank. my relay is working. I am looking for the inertia Switch (as indacated in the haynes manual) between the relay and fuel tank (orange w/ blue wire going in w/ Blk w/pink coming out) any one know were to look??
