Gran Marquis 87 injectors do not serve

I have a great sea 87 and I can turn it on once and then I don't turn on, I have to disconnect the battery and leave it for a while to work. If current is current (+) but the negative pulse that comes from the computer does not reach it, the computer is changing and does the same in the Scanner no code, the lands are well connected that something else could be. Greetings

Good morning friend in the distributor carries a sonsor verifies if this is sending the negative signal to the computer. This sensor acts as CKP in this vehicle, this type of failure is traditional. The current goes to the injectors

Thanks for the information I will check the sensor, greetings
