Volvo Noob with Ignition Issues

Post by jblackburn »

Those are stock Volvo plugs.

As far as the oil up top, nearly all of these do this. Once you get it running and warmed up, pull out the oil dipstick and check for smoke puffing out of the opening. If its clear, replace the cap on the oil seal. If its not, you're in for a PCV system replacement before changing that seal.

It does sound like your problem is definitely with the antenna ring since its sparking (and running!) and then shutting down again. Sometimes cleaning the contacts is enough without replacing the antenna ring.

So I cleaned the connection last night and it started up and run like normal... BUT than i shut it off and went to start it again and it wouldnt turn over. So i went this morning and bought a new antenna ring. Unplugged the battery, unplugged the old antenna and put the new one on and it started right up BUT did the same thing as last night where once I shut it off and tried to turn it back on it wouldnt turn over again!!

ANY SUGGESTIONS?!?! I am very perplexed right now. Does the system need to be reset or something? Is this not the issue?

Clarify "wouldn't turn over" for us please.

Does it:
-Start and then shut off like it was doing before?
-Nothing happens when you turn the key?
-Crank but not start AT ALL?

So I puleld the battery terminals let it sit for a little while and than put them back on and it started up. I let it run and after about 30 seconds to a minute, it died. I tried to restart it and it cranks and doesnt start at all.

Is this a fuel issue? How do i test the fuel pump relay?

THank you

Hmmmm...it could be.

Remove the upper fuse panel cover near the windshield. There are a few Torx screws around the edges.

Remove relay #103 and jumper pins 15 and 87 with a paperclip and piece of wire.

Flip the key to position II and listen for the fuel pump. If you do hear it now, turn it to Start and see if it will keep running, shut it off and try again.

If that keeps it running, you've found your problem!

Worked!! Thank you very much! I ran the wire between the two pins and it started up, idled great and had throttle response. I cleaned the old relay and put it back in and it started and died so this must be it. I am going to go get a new one now.

Thanks everyone for your help.

Glad you found the problem.

Sorry for the run-around at first, but usually a fuel pump relay issue rears its ugly head when the engine is already hot and going down the road or something.

Our Saab died in the middle of a busy intersection when I was younger from the same issue - not a fun memory trying to push the car out of the way!

Well I was on the way back from Delaware and had driven close to 2 hours already and had just stopped for gas so maybe that makes sense now. It is not a problem at all! Thanks all for the input.


Does anyone have any comments on the question I had about the ETM not closing fully? Should it have a gap on the bottom when at rest like that?

Thank you
