There is a ground strap on the firewall above the heater hoses. It appears to go behind the engine. Where exacgly does it go? Pics a plus. I really need to get this hard start,engine codes, poor fuel economy thing figured out. All 4 cam position sensors are complaining and the crank shaft position sensor is complaining as well.

See if this helps. I don't know what year you have, so I just guessed with a 2013. I would assume the harnesses are similar.

Thank YOU Very helpful. I still want to know about the other end of that ground strap. It looks like to goes to the upper end of the back of the block but Where? I ran one towards the bottom of the block because it was all I could access with limited tools it did not help. I also saw what looks like a grounding stud not far above the starter Like maybe the ground strap goes there?

Now can someone tell me about the cam position sensors. We have 2, a 2wire and a 3 wire. Is the 2 wire ALWAYS ALWAYS ALWAYS exhaust and the 3 wire ALWAYS ALWAYS ALWAYS intake? If so bank 2 is bass akwards and probably my whole problem. Who can verify this?

diagram for 13' 5.0 shows 3-wire as intake and 2-wire as exhaust

Yep some engine installer got in a hurry. I'll fix it this week. HOPEFULLY I can talk the wife into a little more time to do it tonight.

what are the codes?

"If so bank 2 is bass akwards" What is "bass akwards"?
The sensors themselves are installed in the wrong location?

Edit: do to brain fart....lol

Where did I miss that on the diagram?

You didn't miss it on the diagram because it don't say, but....

CMP11 is bank 1 intake camshaft sensor= three wire
CMP12 is bank 1 exhaust camshaft sensor= two-wire
CMP21 is bank 2 intake camshaft sensor= three-wire
CMP22 is bank 2 exhaust camshaft sensor= two-wire


two pin/wire= variable reluctance sensor
three pin/wire= hall effect sensor
