Jump start i jumped the car and now it wont start again

Likely, your battery is now history. Sorry . .

Hi if you need to jump start your car then it sounds like the battery's gone, Take it to a mechanic or battery place and get a FREE battery check..... Good luck..

If the lock looks like this, then the security system is your problem.

This behaviour is typical of worn starter motor main contacts, at the bottom of the starter solenoid.

Yah sure check the fuel pressure on the manifold, ur belt tension and altenator. But a very common problem with jeeps is the crankshaft positioning sensor. Check and make sure ur gettin fire. If ur not could also b the ignition control module in the distribitor.

First it sounds like a bad or sulfated battery, if not a loose battery connection. You said they were checked but I would double check, a battery can have voltage but not amperage.

you fitted a flat battery on your car,,,,,thats why it sarted with a jump battery fitted to it,,,,hook up the jump battery again ,,start the car and leave the jump battery hooked up,,,so the car can charge up both batterys,,,till yours has power in it,,,,better still hook up a car battery charget to your car and leavi it on charge for a fuw days,,,

Replace your battery

Try jumping the starter. Or just pull i ,and have an auto parts store test it

Check the safety switch on trans to see if the power is getting to it for the start circuit. If this switch gets old and worn it will drop the voltage so much that it wont start. If it does have voltage then check the wiring to the solenoid for voltage from the battery. The solenoid wire is easy to remove and test with test ligt and a second set of eyes to watch the light when you turn switch
