Valuable information here but unfortunately not all leaks will show themselves through a leak check when applying vacuum to a system. You may have a leak acting as a check valve, vacuum will seal yet positive pressure will allow it to open. But as you have suggested, adding dye will give away...
That’s where checking the fuse relay and verifying power and ground to the compressor is being delivered comes into play. If that’s all there and you then supply power and ground to the compressor wether it kicks on or not will tell you wether it’s electrical or pressure related.
If any ever...
Definitely would’ve started by checking the fuse, power/ground to the connector at the compressor. Or even jumping the relay that powers the compressor to see if it kicks on...
If it was leaking out it would’ve been kicking in and off the compressor noticeably more and more as the refridgerant...
Evac the a/c, diconnect the tubing and very gently bend it to a better angle, REPLACE the oring at that connection. (While the system is apart you may want to go ahead and replace the accumulator and check/replace the orifice tube.) button it all back up vacuum it down, check for leaks and if...
@Bombsquad85 did you preload the torsion bar for reassembly? And remember don’t torque down your control arm bolts completely until everything is installed and the vehicle is sitting on its own weight.
Unfortunately, I’m gonna have to disagree with @zbad55 . Reason being is that the computer is calculating the level of fuel left in the tank to the speed of the vehicle. When idling the miles to empty should go down. On the highway however the longer you drive the more miles to empty will...
I’d check the harness then. Make sure there wasn’t anything that got pushed in the terminal or anything damaged the wiring. Maybe when it was pulled apart.
Are you sure the “known good” sensor is good? You may have got a crap unit fresh from the box. It unfortunately happens.
Just replaced my PF halfshaft last weekend. The flange that bolts to the front diff cracked straight through. I’ll have to get a better pic but the ****** FAILED! lol
It should go off on its own. Have you tried test driving the vehicle? Also, servicing the brake pads and rotors will have no effect on the brake system warnings. The only things that will through a light is speed sensors, brake fluid, abs module and parking brake pedal sensor.
