I have a 92 Bonneville SE

I went to work and when leaving it would crank and crank but not even attempt to start.

I have swapped out and done the following from a 92 Bonneville that is in perfect running order that is owned by a friend of mine.

The only Code being thrown is 58. Which according to my book is Vats Fault but also lists TTS Short Circuit and also lists Transmission Fluid Temp high? I have had problems before with the Vats but on those occasions nothing happened when turning the key, after roughly 30 attempts to start car, it out of the blue would just crank and fire right up. Vats disables starter so this "should not" be my problem and code was probably thrown from one of those instances when nothing happened correct?

Pulled every fuse from under both sides of dash none were bad, I even replaced #6 with a differant 20a fuse to make sure.

Checked the fuses that are by engine on firewall.
Replaced all Relays that are in same place as fuses.
Cleaned battery connections and posts.
Cleaned Ground connections.
Swapped out ICM
Swapped out Coils
Swapped out Cam Sensor

Only thing I havent done is replace the Crank Sensor due to the amount of work involved. I was saving it for when all other "easier" options were depleted.

Thanks in advance.

apparently every 1992 will read a code 58...not sure how that helps you, as i know little about code reading, i've just picked up that tidbit of info from reading other posts

Looks like you suspect it'* a ignition system problem. Have you confirmed this by checking for spark?

All 92'* will throw a code 58. It'* a known bug in the PCM.

Yes I checked for spark and nothing. Just how difficult is it to change the Crank Sensor and do I need to buy a special tool for this?

Sounds like it'* going to be the crank sensor or the wiring between the sensor & ICM. Crank sensor is much more likely the problem.

Another easy test you can try before changing the sensor is to make sure the ICM is getting power. The pink/black wire going to the ICM should have 12 volts while the key is in the run position.

ok the wire harness that plugs into the Crank sensor is extremly loose it wiggles all over the place does that tell you anything or is supposed to move around freely I cant tell because I dont have the balancer off and have never replaced this part. I assume it shouldnt move at all?

I haven't replaced a crank sensor yet. Sure doesn't seem like the connector should be loose.

It shouldn't move. Does the whole sensor move or just the connector?

the whole thing moves quite a bit
