starts and runs great for a few seconds. then tach goes to zero and engine dies. checked distributor and wires. checked all fuses and fusible links. please help.

Install a new fuel filter and fresh gas?

At least make sure your getting gas to the throttle body if you have spark.

could also be a rusted tank and plugged system

 

do you have pressure?

 

will it idle as long as you don't touch anything????

guys, i just went out after cooling it down and it ran just fine. left it running for like 45 minutes. i did unplug the neg side of the battery earlier but still died. just thought i could reset the computer. now its running fine. i will drive to work in the morning and repost what happened. but please keep them coming. the guys that posted, thank you, i did check all of that but didnt post it. thank you and keep up the help. one thing i can say when i started using usmb long ago was the boys.....always keep me on the right track to diagnosing my problems. thanks again to those who have posted.

some of us have gotten pretty good at playing the "diagnose my subaru issue" guessing game

 

good to let us know the details!

If you post some pics of the RX it would help. Ok so it wont help your problem just mine as I have a RX fetish. Keep us updated please.

Dying coil. Tach dropping to zero before engine dies is a strong sign.

+1 to Gloyale on the coil, also have seen the pick up coil in the distributor have similar issues:)

add to the list of things that make the tach go wild

bad alternator diodes

bad dist., even after the hitachi module is replaced

Maybe it's your Enkie wheels? Maybe the RX doesnt like them and you should give them to me.
