1987 Subaru gl FI 4wd ea82

 

Just drive highway and then shutdown..

I seen the RPM didn't bounds and no pre-light warning on dashboard..

 

It's bad ECM? Or what.

Thanks!

Likely the fuel pump went out.  Try rapping on the pump with something a like a screwdriver handle and see if it comes to life.  May take more than one try.  If it does come to life then you need a new pump.

 

If it doesn't, you may still need a pump or there may yet be another problem.  But check this first.

Great place to start is a fuse check, then check the fusible links by battery, followed by the ignition relay. Another thought is the ign switch or its wiring.

already replaced new fuel pump from last year...

 

so, ill check it out for relay and fuse..

Did you guys see his video? His voltmeter shows 0 and the tach isn't jumping around at all...

Clues.

Did you try shooting some starter fluid in there and seeing if it jumps to life for a moment? That'll tell you if it's a fuel issue or a spark issue. If it doesn't jump to life, then maybe your distributor has gone and fubar-ed itself.

Check that the rotor is still positioned properly. The later model spfi engines have a screw in the rotor that holds it in place but can back out, idk if the 87s have that (mine is carbed) but check it out. The two fast turns while it's turning over also make me suspect timing might be off....idk, keep us posted on what you troubleshoot and what happens. Try the starter fluid, just make sure you clamp the air box shut again after spraying it in there because it could backfire, and if the airbox isn't closed you'll get a nice brief fireball and/or fire if that happens.

My first check:  remove disty cap.  Put a wrench on the crank pulley bolt, and see if the rotor turns.  If no, timing belt, if yes, shoot some carb cleaner in the intake boot through one of the smaller lines.  If it fires momentarily, you have spark, need fuel.

Fuse blown. ????
