Electrical problems...starter? battery? ECU? help!
Yesterday my 98 ZJ struggled to start the two times I went out in it and I had to hold my foot on the pedal a little to keep the engine going.
Today I went out to start the jeep and it wouldn't start, it was very sluggish to start over and failed thn started clicking. I thought it might be a low battery so I jumped the Jeep and even then it was sluggish to start and between trying to start one time I turn on the ignition there was a 12v register on the voltage gauge and the next it shows nothing and the engine just clicks.
Eventually I got the jeep to start but once again I had to hold my foot on the pedal a little to give it some fuel to keep it going, after a minute or so it would run ok to drive...not that I trusted it to go anywhere.
After turning it off it once again would turn over very sluggishly and wouldn't fire... after a couple of tries it just clicked loudly. I checked the battery and it registers 12v and the doors lock and unlock strongly.
With the clicking I would suspect the starter motor but what is puzzling me it the battery / fuel gauages not always registering anything and the screen showing 'check battery'.
Has anyone had this and can anyone give me some pointers?
