It will try to start and even sound like it is almost there, but then it doesn’t catch. It is intermittent. I can drive it and turn it off and then start it right back up and it is fine, and then I’ll do the same thing the next time and it won’t start. Another time I can drive it around for awhile then let it cool off and it starts, but then when I do that the next time it won’t start. There doesn’t seem to be any rhyme or reason to why it decides not to start.
The mechanics had it hooked up to diagnostic computers and it has had over 10 hrs of diagnostics run on it.
The first diagnostic tests showed the relay was bad, which is why they replaced it. Then when the problem still occurred they ran more diagnostics and it said it was the fuse panel block so they replaced that but the problem still occurred. Finally the last diagnostic tests said it was the PCM so they replaced that.
This garage has a really good reputation but the mechanics admit they are at a loss as to what is going on. They have been talking to other technicians in the area but no one has come up with a solution yet. Today the mechanic said that sometimes “systems aren’t really connected but they still talk to each other” which is why the diagnostic tests aren’t coming up with the right solution. He said there is a .5 voltage change in the system (I don’t understand what that means exactly) and that every time it won’t start and we have it towed back to the garage all he has to do to make it work again is reset the relay for the fuel pump (which has also been replaced but didn’t help) and then the car will start again. He said that was why they thought that replacing the fuse panel block and the relay would surely fix this.
So tomorrow I will have another towing bill to have it towed back to the garage again (they don’t do towing). I just want to have some possibilities to suggest to them that maybe they haven’t tried.
