2008 TIIDA / VERSA no crank no start
Hi! I'm new, first post....
I've come into a 2008 Versa, 1.5 litre, Automatic trans. It has several issues I'm trying to work through. It's running on three cylinders, cylinder has compression, no spark, but fuel. Different coil modules same thing. There seems to be no trigger for the number four coil.
It now refuses to start with the key. No crank. If I switch the key to ignition, dash lights up. Lights flash, etc. If I bridge the starter B+ terminal and the signal post on the solenoid, engine starts and runs.
The check engine light comes on. I think that's because the engine has dropped a cylinder, though. I was thinking Neutral Switch but after reading the service manual I'm not so sure. The current path to solenoid S+ involves maybe three computers - ECM, BCM and IPDM E/R AND THE NEUTRAL SWITCH.
Power is supplied at all times
•to starter motor terminal B, and
•through 40A fusible link (letter h , located in the fuse and fusible link box)
•to ignition switch terminal B. With the ignition switch in the START position, power is supplied •from ignition switch terminal ST
•to IPDM E/R terminal 21. With the ignition switch in the ON or START position, power is supplied
•through 10A fuse (No. 54, located in the IPDM E/R)
•to park/neutral position (PNP) switch terminal 1. With the selector lever in the P or N position, power is supplied
•through PNP switch terminal 2
•to IPDM E/R terminal 35. Ground is supplied at all times
•to IPDM E/R terminals 39 and 59
•through body grounds E15 and E24. If the IPDM E/R receives a starter relay request ON signal from the BCM over the CAN communication lines, the IPDM E/R grounds the starter relay and power is supplied
•through terminal 19 of the IPDM E/R
•to terminal S of the starter motor. The starter motor magnetic switch energizes closing the circuit between the battery and the starter motor. The starter motor is case ground through the cylinder block. With power and ground supplied, the starter motor operates.
Based on this information I can probably troubleshoot the problem but I don't know if the info is accurate. Nissan is notorious for cocking up their service manuals. Why would the signal leave the IPDM E/R and return to leave again? I just can't get my head around that one.
I have no scan tools. Any help here would be appreciated.
