It's a 1992 model. I was driving along, and the entire power system just went off. The car turned off and it wouldn't restart. It is not the battery because it cranks over and I've had the computer rebuilt since this happened with no success. There is no ignition - no fire to the plugs - and I can't get a reading off the ECM. Any suggestions?

The coils have power to them.

there are a couple things to look at PDM (power distribution module), fuse-able links, main bus fuses (fuses in the engine compartment), and broken wires
Okay so you have power to the coils, so the only thing missing is if you have fuel pressure and a triggering for spark and timing. I didn't get it clear if you have no way of getting the codes from the ecm or the ecm won't power up ?, do you have a "check engine light"?, why it could be a crank sender--i don't think so. I think you have lost power to the ecm. If you lost power to the ECM you would still crank, still have volts to the coils, still have fuel pressure, but would not have fuel injection and spark.

The entire power system did not go off if you can still crank the motor. When troubleshooting a car you start with the simplest things. The engine needs really two things to run, gas and spark. When you turn the key on you should be able to hear the fuel pump. Have some one stand back by the fuel tank and just turn the key to run but do not crank the motor. If you hear the fuel pump running then that is good. Next if you heard the pump running you see if it is getting gas to the motor. fallow the fuel line to the throttle body and unhook it then turn key does gas come out?
If not you have a plugged fuel filter. Take out a spark plug and leave it hooked up to the wire ground the plug to the frame and turn the key. Does it spark ? I worked on a dodge stratus that had a bad coil. Now it took us a long time to find out how to fix it because you can not just buy the coil
it is part of the distributor go to the parts store and ask for a rebuilt one. This was ona mitsubishi engine is that what you have?
there is also a cam sensor and a crank sensor if either of those go out no engine will run. It was a pain in the **** to work on and once I got it fixed my daughter rolled it two weaks later. I hope this has been a help if you want to talk more im me. Does the power get from the coils to the spark plug then?

Replace the Crank Position Sensor. The new one will have a fiber disk on the face, leave it on. The disk is a spacer to set the air gap, just push it lightly against the flywheel and tighten the bolt. The disk will be peeled off as soon as you crank it over. The sensor is directly below the distributor cap, where the trans meets the engine block.

I had a 90 Pontiac Sunbird. Driving along, heard a "pop" and the engine died 20 miles from civilization. No fire, no spark, no ignition. it was the Ignition coil. When it broke, it also kicked my transmission into neutral and fried my after market stereo and blew out some of the fuzes.

there is a big or fat cable that run from engine block to the chassis
please check if isn't broken.
to get some codes out of the ECM,"hook up" the OBD scanner
and make the engine turn with the starter.but as soon as You get the codes stop the starter and let it rest until cools up.
keep in touch.

Your spark plug coils might have gone bad.

Did you see if you had power running to your coil(s)?

Make sure the battery terminals are tight.
