I have a 86 2.8 firebird. Set for 8 yrs. I'm in process of getting it back on road. I have already replaced the fuel pump and fuel tank.My problem is no spark to plugs. I have checked and I have power to coil. I also have tried another coil and still no spark. What should I check next. I'm not really familiar with fuel injection nor computer controlled distributors. Any and all help is appreciated.

 

If the coil you tried was good then the issue is likely in the distributor, could be a bad ICM or pick-up coil (the pick-ups can fail if the car has sat for awhile. You can take the ICM into just about any Autozone or parts store and they'll test it for you. If it comes back OK look at the pickup. It's a cheap part, but you can test it very easy with a multimeter. Gimme a min and I'll find the directions again

 

Alrighty- To see if you have a failed pick-up coil:

Disconnect your coil's wires from the ICM, and kick your multimeter over to Ohms. You want to see a resistance of 500-1,500 Ohms, but 850 is best.

The second thing to check is to set your meter to a high resistance Ohms scale, put your positive to one lead of the coil, and your negative to ground (I just used the ground terminal on the battery when I did this for best results). Do the same thing for the other lead of the pick-up coil. Both of those leads should read as infinite, if they don't then your coil has failed.

You might just be better off replacing this part while you can, an older coil with miles on it may not give as strong as spark as a new one, on my car my high-mileage coil failed soon after I got it running and gave off a weak spark to begin with. After I replaced it the spark was nice and strong, really lit up my in-line spark tester :P

Good luck!

 

Thanks Liveit!, I am going to check those tomorrow.
