Don't know for sure but it sounds like the anti theft system is partially activating when you shut the engine off and try a restart, removing and replacing the fuse temporally deactivates it, granted I'm only guessing here cause I have never seen this but if it was in my shop that would be where I would start. If you have a repair manual take a look at the alarm circuits and switches, it could just be a bad ground. HTH


What # is the fuse?

The fuse # is 40A it's the IG Main


The fuses have a number assigned to them, on the fuse panel cover and owners manual. Is it # 19,20, 21, 23? Those are the 40 amp fuses in the panel under the hood.

It's the fuse located under the hood. It is # 40A it says the fuse is IG Main 40A when I look in the owners book

i will have to look at the cover when I get home. I left it there


19 is the starter relay that may not be resetting, also the ignition switch (electrical on the column opposite ign cylinder) it may be hanging up not letting the car know that its been fully turned off. 20 is the accessory delay relay, if it sticks it will keep things like the radio on. 21 is a main power to other functions in the central junction box(underhood fuse panel). 23 and least likely is the blower motor. The ignition switch is the most common cause of this type of no start condition.
