Everything was fine until the chirping noise. Quickly found out it was the Accumulator.
Followed instructions exactly like they said. Couldnt get the brakes to pump up. So went ahead and replaced the Accumulator and bleed the lines.
Started engine, listened to the pump come on and about 25 seconds later it shut off. Turned ignition off and brakes will not pump up. No brakes at all.
What do we check now?

Hello,

Its sounds like you got a bad (flat) accumulator. Why did you replace it? The pump shuts off because it has ran its maximum time limit. Can you please shoot a quick video with your phone so we can see what's going on, that would be great. You can upload it here with your response.

Well it may take me a few days. But I'll see what I can do. I have the shingles and not doing much right now.
Thank you

Replaced the Accumulator because of the chirping noises under the dash.

Ken is who ask for a video to listen and see the brake system.
We returned the defective accumulator and yesterday received the replacement. It was installed yesterday and the brakes still will not pump up.
Seems like everything is working but pumping the brakes for pressure.
Maybe the attached video will give you an idea of what we need to do. Brake lines have been bled. We even opened the calipers on the rear brakes and let them drip for 15 mins and then did the same on the front, keeping the reservoir full at all times.
Help if you can. Is there a code that needs to be changed or maybe a check valve or something we missed?

Does this car have ABS? if so you will need a scan tool to open the ABS valve while bleeding to remove the air from the system. This guide should help:

Please run down this guide and report back.

Wow! does it have to be a MUT III ? If so we are just out of luck. No way could be afford one of those. Any other scan tool that is way way cheaper?
