There should be a wire that runs from the ignition to the solenoid, check that the wire has power when you turn the ignition key, if it has power the solenoid may need replacing.
Check to see if you have power getting to the distributor and the spark plugs, if you have spark it is possibly in the fuel system

it should take approximately 4 - 5 hours plus the cost of sensor
SOURCE: my cadillac deville needs a transmission solenoid
honestly it would be worth your time and money to take it to a shop
those sensers like to freeze up and when you try to take them out the break off causing you another repair bill
SOURCE: what are these codes for 92 cadillac deville
Hello williamcole7: My name is Roger and I will help you. The code 888 is a test code. This tests the L e d's of the dash cluster. All segments must light so you can read all numbers. The 70 code means the system is ready and able to function. The ff code is a current BCM code and is happening at the moment. The f 40 code is a BCM history code and means it was a stored problem or something that has happened. The f 40 code is for a air mix door problem. THe BCM would set this if you had an A/C problem. The E 48 code deals with the EGR system fault. I would check for a vacuum leak at the EGR solenoid. The hose is prone to deterioration do to heat from the engine. Code E52 deal with loss of voltage. A dead battery or a disconnected battery cable will always set this code. None of these codes will keep the car from running.The repair schematics are to extensive to send in a reply. Should you need further help ao assistance I will be glad to help. Please rate the answer. Thank You for using Fix Ya. Roger
