-im not sure what you are asking there?

-pull the fuel pump relay and start the engine and once it stalls its safe to work on

- keep after it, you figure it out eventually.

- they were ok for big cars wild guess would be 8-9 second range

I think he is asking if he can pull the crank bolt by hooking up a ratchet and turning the starter over. I have heard of that being done, but not by anyone that lived to tell about it. Remove the plastic covers near the starter to get access to the starter teeth on flex plate and jam a screw driver into one of the holes to lock the engine from turning.

Dan and Boosty have done it here on 3800 engines.

Even if you don't hurt yourself I wouldnt risk the damage to the starter or flywheel

Yeah that i meaned but not that screwdriver etc on teeths??


Just insert ratched in and look that it gets support in right position (bolt open way) and show key on ignition lock= starts and tadaa bolt is open.


So only thing that you need is get support to ratchet that it wont punch something on engine base and cut off ignition/fuel that engine wont start and then is hell happening


That does harm anything if you do it right i think.



Does anybody know were fuses are im not founded them yet...?

What is measurements of crank bolt? Didint find on lesabre catalog on rockauto.


Is there some kind of spark plugs (or manufactures) what are definetely bad and not good to buy?


I order many parts of this vehicle and my ford but warehouse locatios goes allways little bit cross so nothing "good" sounding plugs arent same warehouse.

Splitfire? Mighty?


I know autolite and ive used their products (local parts dealer sales them) but i cant get even those now.


Or then i do second order only plugs...

autolite have been alright for me for about 40-50k miles, i usually get some kind of single platinum like delco or autolite. on my daily drivers i put e3'* in them they last a long time and i drive a lot of miles so its worth the money to me.

i have no idea on the bolt size

How about overdrive?

If i drive about 50mph or less, it will switch 3 4 3 4 3 4 very easy. Light gas and it will do it, not without gas so its not terrific.


About 60mph and no problem.


There are 55mph winter speed limits so it saves fuel to drive od but i cant drive it in that speed.


Other cars are swithed od off about 45mph

these cars have very low gears so at 55 its going just over idle for rpm, so if you are on and off the gas it will switch alot. so just put it in drive instead of od, until you are over 55 for a long period of time. to be shifting all the time isnt that good for the trans
