bullittandy Posted February 12, 2009 Report Share Posted February 12, 2009 01 Volvo V70 T5 145K, recently went to start car and after turning the key-nothing. no crank, but all electrical worked well, strong horn and headlights. attempted about 20 cranks, used jumper cables to provoke starter and "banged" on starter to no avail.Came back to car next weekend and it started first time. Not wanting to take chances i replaced the battery (4 years old) and drove the car for two days (about 10 starts) and then on Sunday morning when we're trying to go home-it won't crank again. So..... I replaced the starter with same "no crank". I have tried both keys (one normally used key and 1 valet key)-still no crankThus far, I have an intermittent no crank and i have replaced batery, starter, tried both keys. What I need to know, after searching everywhere on here it seems that my only choices for parts to replace are the immobilizer ring antenna ring and the nuetral safety switch. Which do you think it is? Any other ideas? Link to comment Share on other sites More sharing options...
howardc64 Posted February 12, 2009 Report Share Posted February 12, 2009 I haven't encountered this on my 01+ V/XC70s but I read about Immobilizer causing intermittent no cranks.google "Volvo v70 immobilizer" Link to comment Share on other sites More sharing options...

Do the immobilizer antenna ring. Link to comment Share on other sites More sharing options...
bullittandy Posted February 13, 2009 Author Report Share Posted February 13, 2009 We have a winner. Do the immobilizer antenna ring.Update, I just replaced the immoblizer ring / antenna ring and still no crank. I've got 12 volts to starter (main 4 gauge wire) but nothing to the solenoid wire.What next? Link to comment Share on other sites More sharing options...

The PNP is know to fail in cold weather. Link to comment Share on other sites More sharing options...

harleyhv Posted February 13, 2009 Report Share Posted February 13, 2009 Probably a stupid question.Any Codes / Check Engine lights?Happened to me once - winter time. Quite dreadfull... generated a couple of wtf... Link to comment Share on other sites More sharing options...
jschaefer7406 Posted February 13, 2009 Report Share Posted February 13, 2009 Hello,I've seen a lot of corroded solenoid terminals on the P2 models at the dealer. Did you actually remove the wire and check voltage at the connector, or did you check it at the terminal on the solenoid while connected? Remove and reconnect the small spade terminal at the starter several times to clean it up a bit. I usually crimped the contacts of the spade a little tighter while removed (with a small pair of needlenose pliers), but that's up to you. Apply a good amount of dielectric grease and connect/reconnect several more times. Put the grease right to it, don't be shy . If that doesn't fix it you likely have a bad starter relay. Let me know if you need anything else.Good luck to you,Joe - Volvo Master Technician2000 S70 AWD, 1995 850 Turbo Link to comment Share on other sites More sharing options...

bullittandy Posted February 16, 2009 Author Report Share Posted February 16, 2009 Good info to have as I have yet to see this issue?New update, to recap for future seacrhers:no crank problem:-replaced battery, starter, immoblizer antenna ring, tried all keys, tried starting in all gears, rowed shifter through gears multiple times, checked connections for tightness and corrosionAfter above repairs-12 volts on main starter cable (2/4 gauge) and NO 12 volts on starter relay wire during crank. So... I wired a another 12 volt source and connected to a contact on aftermarkert starter (aftermarket starter had three blades on relay versus factory 1) while starting and car cranked and then... IT NOW CRANKS NORMALLY!!! I have started it 30 times since and still works fine so who knows what happened. Link to comment Share on other sites More sharing options...

External 12 volt source allowed starter to engage and sice then, (with no other changes/repairs) the car cranks normally. Maybe, the new starter was bad and needed a "jump"?

MrWinkey Posted February 17, 2009 Report Share Posted February 17, 2009 I'm still not quite understanding? Do you have a + signal to the small wire running to your starter solenoid on the car(factory wiring harness) while holding the ignition switch in crank position?

I removed the factory starter relay wire and with a testlight determined no 12 volt at wire end- I then reconnected the factory wire and checked again on relay spade-no 12 volt. I then conencted a EXTRA wire from a 12 volt source to an EXTRA starter relay spade on the aftermarket starter and got the car cranked. I then removed the EXTRA wire and now car cranks normally. weird. Link to comment Share on other sites More sharing options...
MrWinkey Posted February 18, 2009 Report Share Posted February 18, 2009 Considering your seperate posts....have you tried something as simple as locking and unlocking the drivers door with the key(not the fob) several times? Link to comment Share on other sites More sharing options...
