I am a DIY enthusiast and have already troubleshooted a few problems using this forum, thanks to you all. I used to work on my motorcycle but now im on to cars which i do not know to much about.
I do know the following repairs where done between 06-08
valve cover gasket set
upper and lower radiator hoses
clutch master cylinder
clutch slave cylinder
replaced exhaust pipe from manifold to convertor
fuel line hose
brake calipers, rotors, and drums, master cylinder
I have personally done:
rear yoke kit
all trying to solve a problem. The engine runs VERY strong but every now and then it wont start. I rechecked the starter solenoid and motor, and battery. When i go to start it, it wont turn over just a click. Any suggestions? The last two times this happened i disconnected the cable that goes from the solenoid to a stud in the body which i believe to be a relay? not to sure but when i reconnected it the jeep started right up. did this a couple times but it doesnt work anymore. If anyone has any insight it would be greatly appreciated
K so anytime i hear stuff like this my first thought is corrosion in the battery cables. Do this quick 5 min check and it may end up solving your problem.
A very common issue with starting is corrosion in between the battery cables and the battery posts. When this is an issue what you will experience when attempting to start is an audible click and maybe failure of the electrical system immediately afterwards. If this sounds like you the first step is to get a battery corrosion cleaning kit from napa, autozone, etc. (about $10). Next disconnect the battery cables from your car (remember neutral first THEN positive), visually inspect the inside of the battery cables, the cables themselves and the battery posts. What you are looking for inside the battery cable connectors is a dull metallic grey film, if you see that you have corrosion and it needs to be cleaned. What you should actually see is clean shiny metal. If you see corrosion use the metal brushes from your cleaning kit and the corrosion cleaning spray and thoroughly clean the connectors and battery posts. Apply anti corrosion spray after cleaning and the anti corrosion felt rings if your kit comes with them. Make sure you reconnect the battery cables positive first then neutral (reverse from when you disconnected them).
Now this will solve your corrosion problem temporarily, you will have to replace the battery cables to make sure you no longer have corrosion issues. You are also going to want to clean any surface the battery cables touch as well.
hope this helps.
