Do you have a security light on dash when key is on?

Customer reply replied 2 years ago
It does. I tried the resistor "trick" but did not work. I bought the "newrockies" bypass module which did not work. Newrockies had me replace the instrument cluster. That did not work. Car will start and run, but shuts off a few seconds later. Problem did not start until timing belt replaced.

Customer reply replied 2 years ago
You there?
Cadillac Mechanic: Tool Hut, ASE Certified Technician replied 2 years ago

I am unsure of why they said to replace cluster.

Check the BATT 1 and BATT 2 fuses in the right side MAXI fuse box.

Under the hood or in the trunk?
Cadillac Mechanic: Tool Hut, ASE Certified Technician replied 2 years ago

Under the hood near the regular fuse relay center. These are BIG fuses.

Customer reply replied 2 years ago
Give me a second and I will double check but I think they are good.
Cadillac Mechanic: Tool Hut, ASE Certified Technician replied 2 years ago

In the trunk is another fuse box. You want to check RLY IGN 1 fuse and the cluster fuse.

Ok

Do you have a test light?

Customer reply replied 2 years ago
Fuses are good. You mean a multimeter?
Customer reply replied 2 years ago
I have a multimeter
Cadillac Mechanic: Tool Hut, ASE Certified Technician replied 2 years ago

A multi meter will work. Under the hood is the starter relay. I have attached a relay schematic can you verify voltage at 30 and 85 while cranking?

IT will be the red wire and the yellow wire

Ask Your Own Cadillac Question
Cadillac Mechanic: Tool Hut, ASE Certified Technician replied 2 years ago

If you have power at yellow and red check the purple wire.

Ask Your Own Cadillac Question
Customer reply replied 2 years ago
I have about 12 at the red, nothing at the tiny yellow, about 2-5 at the big yellow, and about 2-5 at the purple.
Cadillac Mechanic: Tool Hut, ASE Certified Technician replied 2 years ago

OK. For some reason we are not getting voltage from the Ignition switch. are you confident the car is in park?

Ask Your Own Cadillac Question
Cadillac Mechanic: Tool Hut, ASE Certified Technician replied 2 years ago

You can either check the next step at the ignition switch or at the transmission at the park neitral switch. Whcihever is easier

Ask Your Own Cadillac Question
Customer reply replied 2 years ago
Just tried to take out of park and back in park and it will crank but shut right off.
Customer reply replied 2 years ago
Let's go with the transmission. What am I looking for?
Customer reply replied 2 years ago
What should the voltage be on that small yellow wire?
Cadillac Mechanic: Tool Hut, ASE Certified Technician replied 2 years ago

Yes those plugs. Leave plugged in and check both yellow wires. should be 12 volts at both

Ask Your Own Cadillac Question
Customer reply replied 2 years ago
The small yellow wire has about .5 volts when trying to crank. The big yellow wire has 2-5. What should they be?
Cadillac Mechanic: Tool Hut, ASE Certified Technician replied 2 years ago

OK. The ignition switch is not providing 12 volts. can you check the batt2 fuse for power?
