Hello I was having trouble coming to a stop and my engine wants to stall so I finally came to replace the throttle body and did a tune up while under the hood with spark plug and ignition coil replacement and oil change. When I finished I come to turn the key and no start. I continue to replace the fuel pump, Mass, map sensors and crank position sensor. With my finally replace was the fuel injectors. After following the repair Manuel. Its turns on for a second and doesn’t stay on. I did a compression test and it passed with 170 psi every cylinder when I was driving lasted there was some loud noise coming from the engine but they went away. I check all the fuses and nothing blown

Bad vibration at highway speed intermittently. Starts at 75mph and peaks at 80. Factory tires, rotate every oil change. When it slows below 70 vibration stops. Doesn't happen every time and is more pronounced in 2wd vs AWD/4WD. Had tires balanced last rotation and still happens. It feels like its coming from the font passenger side but is not visible from another car following next to me.

Mechanic changed oil in my truck and afterwards an engine light was triggered that said 200amp blown alternator fuse. Mechanic tried to order and it is on back order with unknown eta. So now what can I do?
