Is a 1999 sl2 engine *(block only) compatiable with any other year engine block?

I had 4 saturns, a bad crank sensor mounted in the block behind the starter was the fix which matched your problem. When you get the starter out, replace it too as you will not want to go in there again.

the 1.9 was used throughout the entire run of the sc2 and sl 2 vehicles from the early 90s through early 2000s. Some sensors and accessories may be different but the long block is the same.

I would not remove a 20 year old part, and install an 11 year old used part when a new part is only $30.00. I would not go to the trouble of removing any 11 year old part from any vehicle, especially if it involved removing an engine mount, a serpentine belt, and a cam chain cover, when a new part is only $30.00. I would not attempt to swap any engine parts between DOHC and SOHC engines even if the blocks are the same. Do not put in used wear items as you will end up doing it right again in a few months.

All 91-99 Saturns have the same engine block, the starter is on the back of the engine underneath the intake hardware. very difficult to get to.

The 1995 Nissan Maxima Engine is compatible from the year 1995 up to the year 1999.

In all your years of driving, you never experienced this?

Bad battery
Bad starter solenoid
Bad starter
Battery Cable Issues
A long list of neglected, preventative maintainance items on engine.

I'am not trying to be sarcastic here,but you know the vehicle has to go to a repair shop, to be diagnosed,or you got to start using your knowledge and skills to solve things,then if you get stuck, someone will help you
No one can diagnose over the phone or internet,you need the vehicle

Whatever year has the 1.9l dohc engine, but there always different changes to the motor, like intake manifold or the fuel rail. Make sure if you get a different 1.9l it is the dohc not sohc or you have to get the ecm for sohc. From what I know the 95-'00 SL2 have the 1.9l dohc.

to the back of your engine is the old starter.. Unbolt it (remember where the bolts are.. 2 the side of it.. Remove wires and connect it to new one.. Bolt starter back up..

bad idle air control valve or a misfire,could be alot need more info

make sure its full block dual over head cam (DOHC) it shoud fit. 97 to 99 its the same as far as i know. cause i replaced a 99 with a 97.
