I park the Jeep in january outside until end of march. then i decided to make it run a bit but the battery was dead, so i recharge the battery and then got it started. I let it run for maybe 15 to 20 minute to get a good charge. one month pass and decided it was time to start the Jeep because i got to prepare it for next weekend. But now the Jeep just turn without the fuel pump kick in and of course no spark. :(
I bypass the auto shut down relay and the pump is working, so my question is what does activate the relay seloide for the ASD relay. there is two wire white with yellow strip that goes to the fuel pump and ASD relay. I replace the CSP, change a fuse that was coroded. What else should i be checking.:confused:

i what my Jeep running.:D

what year/engine? my first guess would be the ignition control module, if you have the 258.

12v switched on one side, PCM grounds the relay on the other side to control it.

are you sure the pcm is getting 12v?

same wiring as a standard Bosch relay. Make sure you have switched power from the ignition to the relay.

Sounds like corrosion on the ignition switch contacts. You might try turning the key on-off a bunch to clean the contacts.
