Hi, I hope someone can help me with my problem:
I own a 1988 2.8 firebird, a month ago it sudenly stops to run, it just started about 5 or 6 times but at last it wont start any more. after check I realized there is no spark in spark plugs nor in the coil. I had changed the coil, the distributor cap+rotor and the ignition control module and still no spark. I had checked for error codes in the ecm and it only flashes code 12.
In the past the car wont start but after a day or two it runs without problems. As I'm in spain and here this cars are rare I cannot take it to a mechanic cause I had alredy done and they returned the car to me without solve my problem.
Well thanks in advance, i hope someone can help me.

 

btw, when I say in the past it wont start I mean that some times the car wont start for one or two days, usually It starts with no problem.

 

ignition module?

 

or pickup coil.....

 

check the ignition fuse!!!

 

I have replaced the ignition coil and the pickup module for brand new ones without any result.
If the ignition fuse is located unther the drive wheel I have checked and there is no blown fuse if not please tell me where to find it and I will check.
Thanks for all your help, I cannot check anything till saturday, but I think that if I go to the car with many ideas maybe one is the right one:P

 

Do you know if the distributor is spinning when you crank over the starter?

 

As VernW said, remove the distributor cap, and crank the engine the rotor should turn, if not, it's the timing chain, or something that's keeping the timing gears from turning, or dsitributor gear has sheared the gear locking pin.

Also, you didn't say if you checked for 12volts at the distributor pink wire with the key on.

Do one thing at a time, and you'll find the problem.

 

the distributor spins when crank the engine and there are 12 volts in the pink wire when key in accesory.

 

How about when "ON"?

 

add to my check list for fryday

 

12volts when ON/RUN/START

 

12 volts confirmed
BTW someone tells me thet white wire in coil is trigger and coil should fire if I ground it, I have done it and the coil not fires but I have spark on the wire I use to ground.

 

Hi I just forgot about this post,browsing the forums I rediscovered it, I finally found the problem with the spark, it was the pickup coil inside the distributor, it was broken. I change the distributor (I just cannot find the pickup coil itself) and it starts now. After that i had some more troubles but thats a diferent story. Hope that if someone have ever a similar problem this helps him to fix it.
Thanks a lot for your help.
