ok. i have tried every thing.

this is how it happened . my 87 2.8 started dieing when it would heat up. and when i let it cool down it would start right back up again. now it wont start at all. i have changed the ignition coil, control module distributor cap and rotor ignition switch and they are all new no used parts.

i have 12 volts going into the coil but still no spark. the pick up coil does read the right OHMS as well. wich is .836
any ideas? im stumped

Spark plug wires or distributor might be bad.

the distributor rotor turns good and it was running great then all of a sudden this happened. how could the spark plug wires all go out all of a sudden?

Well honestly it sounds like your burning up your ICM, are you putting dielectric grease on it before you put it on the distributor plate? Generally when it dies after it warms up and you know its ignition problem, then chances are a component overheats when you have it running, which is why if you let it cool off it will start again. I don't really know the name of the part offhand, but if the coil thing(not ignition coil) part of the distributor itself is in bad shape, ie. rusty, or wire insulation gone and such it can make your ICM or ignition coils burn up, also I've heard a good many rantings about aftermarket replacement parts, namely sensors, being highly unreliable and failing shortly after getting them.
To rule out ICM failure, have an autozone test it for you, to rule out distributor itself, take off the coil plug from the cap, check for spark with a screwdriver, if you have spark there, then you know your coil is fine, and its almost definitely the distributor.
Last but not least it could be the wires, namely if they're the originals, even if they look fine they might have a break, could also be the spark plugs.
You really just have to start at the source and see how far down the line you still have spark, if it all.

i had the "ignition control module" checked and it is good. also had the ignition coil checked good as well. the coil in the distributor tests fine but does have a bit of carosion. why would i be getting power to my coil but ii cant get spark from it. and i tend to doubt the wires are bad just because they look fine and they where working fine before all this happened? maybe im just not seing it the same way

thanks 3rd gen rs

check the coil pack by the egr. sounds like it might of took a dump.

Check the wires on the 2-wire jumper that is the black connector on the coil, running to the 2-wire connector on the ICM. The ICM gets power from the pink or whatever color the non-black wire is on this connector (mine's faded and looks tan). I had one break while I was at school and had to hunt for a replacement connector.

Also, check the resistance of the pickup coil in the dizzy and also to make sure that it's actually connected to the ICM when plugged in. I know that the terminals in my old one wouldn't stay in the connector unless I physically pushed them onto the ICM terminals after the connector was put in place.

thanks maverick i will check those out
