Right now as the car sits I have a crank no start issue. I have checked grounds, fuses , ccrm connector and wiring and the module ( opened it up for a visual)
With communication I have power to the IFS and also the fuel pump driver module seems to be in working order as well...
With the key initially turned to the on position I can hear the ccrm relays click. Next one of two things happen 1) it clicks again and the fan turns on, and I have no communication with the PCM (cluster is all dashes)
2) it only clicks once and the fan stays off and I have communication with the processor.
Today a buddy of mine came by to see if he saw anything I was missing. We decided to supply 12volts and ground to the pump to verify operation and nothing. So I believe I have two issues. 1) intermittent no communication with the processor 2) fuel pump has died.
My next step is to replace the pump and see if the car runs when I do have communication. However I need to figure out exactly why I don't have communication with the processor to completely remedy the issue.
Does anyone have any suggestions on what to look for in the system ?
I have electrical schematics and a multi meter, but no manual for pinpoint tests which I rely on for these type of issues or situations.
If anyone could help me out that would be awesome, and I will make sure to post results so if anyone has the same issue they can read an entire thread without getting to the end with no solution to the issue.
Thanks
