87 trans am TPI 305 auto.....no spark at spark plugs but i am getting a good strong spark at the coil...ive replaced so far- the coil wire,used distributor,new cap and rotor and plugs and wires...anything i could be missing?? PLEASE HELP!

 

Ignition control module under the dizzy

 

If you're getting a good spark at the coil, just not all the way at the plugs, it's not any electronics, it's either in the distributor, cables or plugs.
You say you replaced everything in the high voltage path but still don't get spark at the plugs? That's very strange. But you can find the problem by method of elimination.
You can for example take every spark plug and put the coil wire on it and if it sparks, that plug is good. Do that for all 8 plugs to eliminate broken ones.
You can bypass the distributor and connect each plug wire to the coil and see if the other end sparks. Test all 8 wires this way. That will eliminate broken ones.
Make sure the rotor under the cap has a good springy contact and that it touches the cap center post. Make sure the rotor is long enough and not too worn and burnt.

In case you didn't know, when you turn the key on, the coil's primary side gets power. You can then ground the white wire on the coil primary to manually throw a spark on the secondary side. No need to crank the car.

Hope this helps.

thanks alot! ill try this and let ya know

 

Let us know what ya find out!

 

figured it out! my timing was off by alot...i had a friend help me get it right then it started right up! then since it hasnt been started in so long the power steering line blew then i noticed coolant pouring out of the back of the intake and i have a blown breakline! great haha i got some work to do now but at least she runs! anyone know where i can the code on this car so i can try typing it into the RPO decoder? its an 87 TA thanks!

 

Its always a good idea to start the car (at a minimum) every 30 days just to keep things from drying out or rusting.
I had a friend of mine who owned an 84 Trans Am and worked at a car dealership. He was able to drive company cars and parked the TA for a year. He then left the dealership and needed to drive the TA again..It started but had absolutely no power (could barely make it up a hill)...The problem? His exhaust had rusted so bad on the inside (especially the cat) that the car couldnt breath.

 

no kidding huh? but i just bought the car so everything is new to me but it did sit around for awhile...the exhaust is all factory tho,but that'll change soon when i get my edelbrock headers and y pipe and hooker cat back in =) the car seems to be running crappy and is comin up with a code 34....which is the MAF sensor or MAP sensor.....any help or suggestions to this? thanks
