omega_rugal Posted March 10, 2017 Posted March 10, 2017 never mind, guess what was it? a solenoid... :fs1:
cruiser54 Posted March 10, 2017 Posted March 10, 2017 Good question, I will check that as soon as I have a chance and report back. How long should I crank the motor to get a voltage reading? should the reading be steady? 5 seconds/

omega_rugal Posted March 11, 2017 Posted March 11, 2017 never mind, guess what was it? a solenoid... :fs1: Which solenoid is that? either the B+ latch or the Fuel Pump wasn`t closing properly, to be sure changed both, it`s working so far...

Coulda found that out by moving each of the relays over one spot.
big66440 Posted March 16, 2017 Posted March 16, 2017 My CPS was soldered directly to the ECM, I guess there was a TSB to bypass the "harness" so the ECM gets a stronger signal according to some bits of info I found?. I placed an order for a new Mopar CPS ( Part Number T0739789 ) and have 2 Delphi weatherpack connectors to do it right. I'm planning on modifying the new sensor to advance the timing and drill the holes to get it closer to the flex plate to cover all the bases.
Ωhm Posted March 16, 2017 Posted March 16, 2017 I'm planning on modifying the new sensor to advance the timing and drill the holes to get it closer to the flex plate to cover all the bases. Won't this affect INJ timing also? I understand the 'closer' side of this, but moving the pickup, changes TDC.

If I remember correctly, the bulletin replaced the CPS with one that had a slotted hole in it for the upper bolt. Still had a plug, but a harness was wired through a hole drilled in the firewall and the harness was pinned directly into the eCU. I could find it if you want. Longer crank times can sometimes be caused by a bad sync generator. There is a test procedure for it somewhere. since I have the factory tester I always rely on that to tell me if it is good.

Sync signal determines INJ sequence. INJ timing uses teeth count on the flywheel. Not here to start a pissing contest, just a understanding. Maybe a new topic, don't want to hijack thread.

Hmmm. the ECU has a default for determining sequence. I believe that's why a bad sync generator's only symptom is longer crank times. And, the factory made their own high altitude CPS which had the sensor portion moved on the mount. See here: http://cruiser54.com/?p=127
