I changed the spark plugs for the first time on my 03 Disco II. I did not take the intake off, boy that is a nightmare. But I did get them all changed with the plug wires. But now the disco will not start. It just clicks at me as if out of battery. But when I hook up the charger, it tells me the battery is fully charged.

Any ideas of where to look? I am at a loss as to what I may have done. Thank you in advance for looking.

 

check to see if you have the battery terminals back on nice and tight.. I would loosen them take them back off clean everything real good. then take a 2.5lb mallet and tap them back on. tighten and try to start then.

 

Just curious, what spark plugs did you buy?

 

Reset your inerita switch on the fire wall, also lock and unlock you door 3 times in a row, then try.

 

Well, as it would have it, it was a misty day and my charger was acting up. The battery was low. I charged the battery and she started.

But, lol, I constantly have a flashing check engine light now. I guess I am off to the local parts store to have the codes read.

I install the bosch +4. I think I purchased the last 8 here in town. I was told they are not making them anymore.

thanks again

 

probably a multiple misfire code. May have swapped a plug wire., or one is not seated fully. See attached diagram.

 

UPdate... To mornings in a row with a dead battery. Charger acts like there is something on when charging. This morning after a jump start, the m & s lights started flashing. I also noticed one of the plug wires was not connected at the plug. Going to disconnect the battery from the terminals and try charging it to a full charge.

No chance for codes yet.

Thanks for your help.

 

Thank up for the picture. i had that with me while changing the plugs. that was rough getting on top of the motor to disconnect and reconnect the wires.

 

happy update....
No more codes, flashing M&S lights, or dead battery. The problem turned out to be my passenger seat heater was turned on draining the battery and when attaching the charger, making the charger not charge correctly.
The seat heater was constantly on because 2 weeks ago the key broke off in the ignition switch. This is my next project to try and get that broken part of the key out.

 

You can disassemble the steering column and unplug the ignition from the IDM and remove it to get a better chance at getting it out. Not a super hard task i have faith in you!
