    3.0L hard starting when warm

    This manual shows you should not have continuity at 110F and should have continuity at 130F. I get no continuity from 70F to 150F. I’m guessing the sensor is bad since it never closes the circuit and provides a ground

    3.0L hard starting when warm

    Sorry for the confusion but I wanted to know how test the TKS temp sensor. The TKS module seems to work since I hear the hissing sound during startup when cold and goes away after about 8 mins. The back of the module is hot to the touch. When I turn the engine off hot there is no longer 12V...

    3.0L hard starting when warm

    Definitely a bad sensor. Is the ring terminal near to starter solenoid supposed to be hooked up to something?

    3.0L hard starting when warm

    I verified the tks works. I hear the “hissing” and the back of the module gets hot. When the engine is running the module has 12v power. The issue is that when I turn off the engine hot there is no voltage being sent to the TKS module. Im assuming the sensor is bad and replace it. What are...

    3.0L hard starting when warm

    Sorry for all the questions. Are you referring to the 12volt lead going into the tks module? What do you mean by the other side? the other wire going into the module? Doesn't the oil pressure switch provide a ground path for the TKS module once it senses oil pressure then once up to temp the...

    Timing issue 3.0 TKS

    Do I adjust idle rpm when in base timing mode? Also installing and removing shunt should always be done with the engine running correct?

    Timing issue 3.0 TKS

    I am having some issues on my 2005 3.0L serial number 0W306422 engine. I jumped the 2 white wires from distributor, and bypassed the shift switch like the instructions said, runs like crap at 2 degrees atdc. The only way it runs good is setting timing at 10-12 degrees btdc. Do I set idle...

    3.0L hard starting when warm

    Should there always be 12V going into the module with the engine off and key on even when the engine is warm?

    3.0L hard starting when warm

    Just assumed it was flooding. I had to move the throttle to WOT in order for it to start which took several attempts and once it started it seems like the engine was stumbling.

    3.0L hard starting when warm

    I have a 2005 mercrusier 3.0L with TKS carb. The boat starts instantly when cold but starts really hard when warm seems like its flooding itself. I replaced the dist cap , rotor, spark plugs, spark plug wires, and fuel filter.
