84 Olds omega - no fuel, no spark

Hey,
first off let me thank the people that own this site for providing free help and such.

Well, my 84 Oldsmobile Omega(2.5L 4cyl 151 R) failed to start yesterday.


I originally thought it was a fuel issue because NO fuel is comming out the injector. I then got a free injector from an old truck from my mechanic for free. tried to put it in and it did nothing. The wires leading to the injector are getting voltage. So I ruled out the Injector. Then I bought a fuel pressure gauge, and I came to the conclusion that its not the fuel pump, or the fuel pressure regulator.


After that I was stumped so I tried pooring gas down the throttle body to atleast see if it would start, nothing.


I then relized there wasnt even spark getting to the spark plugs.


Does Anyone know what this might be?
If anyone can help it would be much appreciated.
thanks

Re: 84 Olds omega - no fuel, no spark

Could it possibly be the coil or pick-up coil?

Re: 84 Olds omega - no fuel, no spark

Im guessing the Electronic Control Module?

Would this be considered the computer?

Re: 84 Olds omega - no fuel, no spark

Is it the ingnition control module, or electronic control module??

Where is it located?

And would this really make no gas come out the injector?

Pick up coil and module are in the distributor. If the pcm does not get a signal from the module in the dist it will not trigger the injectors as well as the possibility of no spark.

Re: 84 Olds omega - no fuel, no spark

I cant even imagine changing these parts lol... The cap + rotor took me 2 hours to do because of the location...

The distributer is behind the engine, any technichs to do these easier?

From the bottom?

Im definitly changing both the module and pick-up, I dont want to do this ever again lol

And also, just for insurance this is the module you speak of right?

Thanks, you should get paid for your advise your better than ny mechanic ive ever talked to and your not looking at the car.

Well, 25 years with Cadillac/Olds has some advantages. Check autozone.com/repairinfo for some specific info. Hope the distr. work fixes the car, remember to check the wiring fom the dist to the ecu/computer make sure no loose or corroded connections. Good luck. PS yes that is the module, post back your results also.

Thank you for this Post!
Gramdma's low mileage 1983 Oldsmobile Omega died, and replacing this Ignition Module has it at least starting again. It now will start but lacks power, and still throws code 42, Electronic Spark Timing Problem (Check Engine Light).
Besides checking for coroded wiring connectors at the distributor, between the distributor and the computer, is there anything else you would suspect?

Is this 25 year-old car now eligible for Classic-Car License Plates
