So I went out this morning and I tried to start my vehicle. I think I've got a problem. I tried turning it over and it didn't want to start. My glow plugs are wired to a button that I push to turn them on. I hit the glow plugs for a few seconds and let it warm up a little bit. I went to crank it and it would just crank. Finally I tried holding the plug button and turning it over and it started but it started pretty rough. I drove it to work and it doesn't sound right. The turbo sounds like it doesn't push as much boost. If anyone has any ideas shoot em to me. Thanks guys.
