Thanks for the S/N it allowed me to be sure that 7745609 is the right wiring diagram and that it was wrong when published, is has since been amended by service bulletin group 04-2 number70 version1
The wire you are looking for is the pink with dark green tracer. All 8 injectors will have this wire going to them. All of the second wire?s at each injector will be different, tan with green, tan with brown, green with blue, green with yellow, ect.
This pink with dark green will also go to the ignition coil and ignition control module.
This wire is the key on power for the injectors and ignition. Until you fix that you can throw all the parts at this engine that you want and it still won?t run.
I?m pretty biased about aftermarket ECM companies like the one
AllDodge posts. This is because I?m the guy who gets to fix the boat when something they do causes problems. My last repair like this was a customer who had his ECM modified and now the boat has intermittent warning horn and goes into power reduction. He brings the boat to my marina and is now willing to pay the $150.00 an hour for me to troubleshoot it. It took me an hour and a half to determine the ECM is causing it. Trouble is the company who modified the ECM say?s what they did couldn?t possibly cause this symptom and refuses to do anything about it. So the customer is back and isn?t happy. He now pays for another 4 hours of my time to rerun all the tests and document them, included in this time is me waiting on hold to talk to the modifier and explain how I?m sure the ECM is at fault. They agree that ECM is bad but stand by their story they didn?t cause it and try to blame me. I tell I never saw the boat until it had the problem, so they blame the customer. Long story short is the customer buys a $1500.00 ECM from me and the boat now runs like it should. This is one of many horror stories about aftermarket parts and suppliers. I look at them a lot like salvage yard parts ---- sometimes you can get a great deal and sometimes you can get royally screwed, most of the time its somewhere in between.
I will tell you anytime you hear a mechanic say ?I think it?s the ECM? runaway FAST. Those words should never come out of a mechanics mouth.
If you want to order an ECM from Volvo its part number 3818619 Module ECM $1, 564.00 US
Also 3863130 Sensor camshaft position $238.35
Are these parts bad? At this point nobody can know BECAUSE YOU DON?T HAVE POWER TO THE INJECTOR?S
You can fix the harness or replace it. 3888188 Cable Harness $1,139.83
P.S. according to Volvo Penta your engine serial number has never been registered. So I have no idea if there are any open recalls or updates to this engine. I suggest you call them and get it registered.
