Most likely a magnetic pickup or brain box.

Also unplug/replug in the CPS sensor. SignatureDougW I used to have an 87 YJ with the 258 and this happened to me. For me it would mysteriously quit, and when it occurred it was right after it started or it would not start. Cranked fine. If I walked away it might or might not decide to be OK again. I replaced the ignition control module and it never happened again. The ICM is a silver colored flat box that is located in the wheel well (driver's side, in with the wheel, if I am remembering right) of all places. I followed the wire to find it. 6 years ago it cost about $50US. It just unbolts and unplugs, easy as cake, once you find it.

It doesn't have one. Most likely a bad ignition module. >I have an 87 YJ with an 258 six in it and today I was backing out of the >driveway and it stalled...tried to restart..fired for a couple of seconds >then quit again...now it wont start at all....rolls over very well >....getting fuel...seems to be no fire...any ideas what to check >first...thanks in advance That sounds like either the ignition module or body ground strap have gone bad to me. Because you were in reverse, I would look to the ground first. That is a mesh cable from the engine head to the firewall. I test them by running a booster cable from the battery negative to the firewall and see if they then run.

It should have between 400 to 800 ohms on the orange and purple wires. The coil primary circuit should have 1.13-1.23 ohms cold and 7700-9300 ohms on the secondary.

Ya know, the odd thing about measuring coils.. I've tested at least five that measure fine but were actually dead. They all had a high voltage break down and arced out inside. Measure them at 9V with a DMM and they look fine. That's why I got one of these thingies. http://www.thetoolwarehouse.net/shop/THE-404.html >> Tried both things...new module and ground strap still nothing...could it be >> the coil?
