A ticking noise when starting up

Left work truck was fine stopped at store came out started it up and I lost powersteering and brakes are hard. Thats when i seen the return hose to the gear box was off. I replaced the power steering pump and the Hyrdro-Boost. Tried to bleed the hydro-boost but nothing comes from the return hose. I believe there is high pressure on both sides of gear box not allowing flow or there is blockage in line or a seal has failed somwhere. Please help.

Battery is good. electric door looks don't work, radio gets hot

My gauges are not working properly and the service man from GMC said it was due to a wire shortage for the cluster. Does a fule gauge sending unit work along with the cluster? My warranty said they will not cover a cluster but my fule gage does not work along with the other gauges?????

i was driving one day and my truck just turned off and wouldnt restart

Fuel cap? Ground at the PCM? How do I check it?

I replaced thekey switch on my Yukon now it starts and dies I need to know how to reset the anti theft system

the problem occurs every three for four weeks when the coolant is all gone. i been hearing it due to the bad head gasket and The water jackets leak into the cylinders and the coolant expelled out the tailpipe

I ordered my fuel pump offline for a low price and I replaced my fuel pump on my 2004 Yukon and now the fuel gauge isn't reading.Thought the fuel pump was bad so I replaced it 2 more times, had it put on the machine at the shop and there's nothing wrong with the instrument panel(gauge) so can something else be wrong.HELP PLEASE
