Dear Phil, Art, CB, et al,
I had a tough week at work and forgot about the car for a while. Then I come back and find all this help waiting for me. Apropos the season, I am thankful.
Phil, I didn’t know about the starter fluid test. Art’s picture and directions will make it virtually impossible for me to screw it up. I will do the test tonight and report the result.
Phil: The reason you might not be getting a reading on that grounding wire Y/B is you are not ACROSS the potential of the battery circuit. From what I can tell from the instructions, it does not tell you what you have to do to get that reading with your measuring tools.
I need to understand this. Good point.
Phil: They assumed that the technical person looking at their manuals have some understanding of electrics.
That seems like a fair assumption. Would that it were true in my case.
Art: "spark at plugs" and "fuel in the rail" don't lead me to assumptions like "Fuel injectors are not injecting."
Good point. I have no idea if the fuel pressure is adequate for injectors to function. But with spark and compression, I thought that if the injectors were injecting the car would run in some fashion. And I didn't feel any injector pulses through my screwdriver on the injector bodies when my friend cranked the engine. On my 245, I feel these pulses distinctly.
Art: I have a feeling I've already told you my tale of using a refrigeration tap to make a fuel pressure gauge adapter.
I would like to learn that twice told tale. It sounds like a useful modification.
Phil, you are right in noting that I am so slow to make progress. I have a kid to raise, 2.5 hours a day commuting (in a 245), and 50+ hours a week at work. But I am slowly learning a little about how my car works. This is interesting. It makes me feel good about myself. It deepens my long held appreciation of old Volvos. I am confident that by putting the advice and the information provided here to use I will have earned the right to be driving my favorite car again. Eventually.
Phil: He said he went through the wiring covers under the engine but it's true he might still have a rats nest like your picture very adequately shows.
I don’t think so Phil. Everywhere I look, poke, probe, and clean, the wires all seem to be ok. They appear to be physically sound with no signs of deterioration. However, as you know, I am often wrong.
Art: I'm glad he didn't go for changing the shaft seals on this go-round.
It was hard not to, with them right in front of me. But I trust good advice.
CB, you are right. I did not read the Volvo Problem Solver book. It intimidated me, and with all the pages I’ve printed and the Bentley manual I’ve been looking at sporadically, I blanked out a bit. That is, until you gave me the specific sections to learn. I will print these out and study them carefully. Thank you. The hardest battle for me is psychological. Believing that it is possible for me to do the job is the toughest part.
Bill N, thanks for sharing your good luck in replacing the Ignition Control Module (ICM) on your car. I appreciate the suggestion. In my case, I got a spare at a junkyard and swapped it in, but there was no difference. I wonder about that long problematic vacuum line coming out of it and snaking all the way to the other side of the engine…
