STILL has issues starting when cold! I have done injectors, glow plugs, glow plug holes, new battery, new glow plug temp sensor, getting correct voltage at each plug, correct resistance in all the harness wires.

most recently, i replaced the glow plug temp sensor and it made the problem worse! tons of white smoke, missing an running like poo until it gets to temp. i guess because now the light stays on for only 2-3 seconds when it's in the 80s out.

however, when i disconnect the glow plug temp sensor and let the glow plugs burn for 15-20 seconds it fires right up, no smoke, no miss and runs smooth.

WTH am i missing!!!??

for now, i have zip tied the disconnected temp sensor harness to the dip stick tube and i am just letting them burn like i said for 15-20 seconds. Is there any harm in doing that until i figure out what the heck is going on?
