So I have a 1999 Parker with a 5.7 Gsi engine.(model pwtr or something like that I believe). I started it after its winter hibernation and it started ok and ran for a bit. I noted the starter was making some noise(like bad gear meshing) when starting so I ordered a new one and replaced it(new one sounds good). I then attempted to start it. It turns over fine but no start. I noted I didn't hear the fuel pump 2 sec prime when the key is switched on so I located the fuel pump relay and determined that the coil was not being energized. I then replaced both the fuel pump and ignition relay as there both the same age. Turns out the ignition relay was actually shot (switch contacts not the coil) but upon replacing them both still no start. I located the wiring diagram, http://boatinfo.no/lib/volvo/manuals/ef_wiring.html#/10 and now I'm trying to understand both the ignition coil activation and the ecu turn on power. Looking at the diagram it appears that I have the wiring diagram for the 4.3 Gi listed in this manual vs the 5.7. I say this only because I have four wires coming out of my ignition coil relay vs three shown in the 5.7 wiring diagram? Which brings up my next question, how is this coil (of the relay) activated. My understanding is that the purple wire(which really seems more pink on my harness) go to the exc input on the alternator which supplies a voltage to the alternator when the key is turned to the "on" position. If there is no voltage on this wire (which there isn't) how does the ignition relay get activated ? Is pin number 9 on J1 the power up pin for the ecu? I've checked my grounds (rear of engine where the battery connects (cleaned and checked them out with an ohm meter)all seems good there. Thanks gents in advance...
