How’s it going I was hoping to see if any body knows what this cable is. I’m having trouble with my truck starting and only makes one click when turning the ignition. I’m assuming this cable is the reason why it’s not turning on

 

Probably has nothing to do with your starting problem.

The engine type and photo orientation are not clear, but your item is either an oil pressure sensor or knock sensor.
Neither of these being disconnected would keep your machine from starting.

 

i think that is your oil pressure sending unit/sensor wire. just turn on the key and start the car and check to see if your top left oil pressure guage is functioning or not.

for your 1 click problem start troubleshooting the easiest things first.

check your battery connections for corrosion first. remove and clean the cables and battery terminals and reconnect.

Check your batter cable leads very closely for corrosion WITHIN the cables/plastic covering. overlooking this simple thing can lead to a witchhunt and lots of money you dont need to spend.

Have your battery tested

if all of the above check out, then remove your starter and take it down to local AutoZone/Orilley's/ Napa, etc. i think they all test batteries and starters for free.

 

yup , its for the idiot light on the dash , oil pressure light .

 

How is everything now?
