Hello and good morning.

Expert:  Ivan replied 1 year ago.
Ok, I would like to start with something simple. With a voltmeter, let me know the voltage of the battery at the terminals, then at the battery bolts themselves that connect to the battery. Then try to see what is at in the cable itself. I am looking first for high resistance. On the battery cable side, see what that voltage shows when you turn the key to start. Let me know what you find.
Customer: replied 1 year ago.

Good morning


 


The car is at the customer house


Tested at their house yesterday with test light


She was driving the car and then the dash light started blinking, so she turn around and park the car


Voltage is at the fuse box until the key is turn on then no voltage on battery cable at fuse box and on max fuses

Expert:  Ivan replied 1 year ago.
Then look real closely at the battery and the battery connections. Your problem has to be there. Look for corrosion where the battery bolt goes into the battery cable. Look also to see if the battery voltage drops also when the key is turned on. I truly feel the issue is going to be in that area.
Customer: replied 1 year ago.

I'm going to check the car, will be back online in an hour

Expert:  Ivan replied 1 year ago.
Ok great, I'll look for your post.
Customer: replied 1 year ago.

-fuel pump runs no stop


-no start , no sound clicking or nothing


-headlights stays on


-trunk and gas door don't work


-95% of fuses in fuse box underhood and under back seat with power with ignition switch in off position


problem a dealer job

Expert:  Ivan replied 1 year ago.

Have you addressed the battery yet?

Customer: replied 1 year ago.

check voltage and replace battery


now voltage does not drop when switch is on


fuel pump runs with no key in switch had to disconnect battery


sounds like something is melted together, holding the fire

Expert:  Ivan replied 1 year ago.

Ok, can you unplug the fuel pump relay and get voltage readings on each terminal of the socket? Let's find out why the pump is staying on. Let me know if you need locations

Customer: replied 1 year ago.

only check voltage only on one side, even change relay.and the dash stays on sometimes without key

Expert:  Ivan replied 1 year ago.
Does the fuel pump shut off when remove the fuel pump relay?
Customer: replied 1 year ago.

yes

Expert:  Ivan replied 1 year ago.
Then the PCM is keep the relay grounded. Can you get codes via a scan tool out of this car? Body control module codes? Instrument panel codes?
Customer: replied 1 year ago.

No!


nothing scans


operator error

Expert:  Ivan replied 1 year ago.

Then I feel you have a PCM that has failed. It is keeping the fuel pump grounded. Unplug it and see if the fuel pump turns off. I am going to send you pinouts for the PCM. Make sure all powers and grounds are OK and present. I have to step out for a little while, but tell me what you found when you check these points at the PCM
