I have problem where fuel guage reads full when full & is empty when guage reads 1/2 full...

This was after new Airtech fuel pump with level assy was installed in an attempt to remedy low fuel pressure issue... also have intermittent guage /cluster failure, airbag light comes on and off, door locks work then don't work... & engine will not stay running when started...

All these issues occur intermitently except for fuel guage reading incorrect... everything fine for a few weeks then no start/run, no door locks, windows, guages go to zero.... so i give up.... come back later turn the key & everything is fine for a few days or weeks then... some magic occurs & it just turns off while dirving...

when it does not want to idle - if I hold down the accelerator a little bit- it will stay running & allow me to drive, but when the accelerator is fully released the engine dies...

I have taken it into the shop - no codes - and no problems - some majic happens & everything is ok... the mechanic has kept it for over 3 weeks on 2 different occasions and used it as a daily driver & for shop erands with no repeat problems ... this has happened twice now & the shop guys have no ideas...

could there be sensor issues where an intermittent break would cause a shutdown... i.e. bad connection or intermittent break in sensor wire/connection to temp sensor, crank position sensor, etc. would cause this... or would bad connection/ground to door locks, windows circuits be involved???? this is too bizarre... & a long standing issue...
