Rebuilt Engine Rough Running
We rebuilt the engine on the 2007 Hummer H2 and replaced everything including all electrical sensors. The engine barely runs and gives Throttle Position Sensor, Camshaft Position Sensor and Crankshaft Position Sensor codes. All are brand new and replaced twice in case they were defective. What are we missing?

Help with 07 h2 hummer oil pressure sending unit/pressure sensor
HELP... I'm trying to replace the oil sending unit (OSU/OIL PRESSURE SENSOR) on a 2007 H2 Hummer 6.0 L vortec engine. I have the new OSU and special deep socket for removal. I know it's located at top back of engine against firewall on steering wheel side. I can see the wire leading to it but My problem is I'm a big guy and I can't even get my hand back in there to remove the electrical connector off of the sensor to even attempt to replace it. Keep in mind on the H2 Hummer the hood lift straight up and stays at a 90° angle when open so you can only work from the sides of the vehicle / engine bay. I've attempted to get back in there with a flashlight but there is the fuel rail in the way, evap solenoid line, electrical loom wires etc. So Any suggestions from an experienced mechanic that has done this before on my particular vehicle? Tried to get my hand back in there but it was so tight I couldn't even use my finger tips to unclamp the connector. Any tips, input, photos, suggestions would be appreciated. This is truly a nightmare to get done. I need some guidance Thanks in advance 👍🇺🇸💪
