Cranky no starty
a bit of history:
I got a 91 xj off of craigslist for $350 with blown head gasket issue.
I replaced the head and a lot of other parts that needed replacing.
Jeep is oiled up and coolant is filled.
New plugs and distributor cap.
The battery is dead. I tried to charge it up but no go.
I hooked up my jumper cables on my other Jeep to this jeep and when it tries to crank.. it wont start.
Heres a wierd thing: when i turn the key to crank it.. i hear the starter go and then i feel the "juice" slow down so i back the key to off but the starter is still trying to go? what would cause that?
When the jeep was in the blown gasket stage.. it started up and ran.
Any ideas? is it as simple as replaceing the battery?
Thanks
Mark

couple things could cause a no start:
Timing
Firing order
Sensors Unhooked
CPS
Fuel
Spark
Check the sensors you replaced and any sensors you had to unplug to take the head off. You could also try resetting the computer, unhook the battery for about half an hour and try it again. Sometimes a bad battery will screw with the computer.
Also, It sounds like your ignition switch is bad. Maybe it isnt sending the "run" signal to the computer, but still turning the engine?

What about the ground on the back of the head to the firewall? Double check everything, i'm sure it is something simple that you have overlooked.

You have spark?
If you have spark, spray some Ether into the intake and see if itll run.
Not alot though, It washes the oil off teh cylinder walls if you use too much
