My 1989 Volvo DL starts and works well some time but then I go to and it will not start.

SOURCE: 98 volvo s70 stalling out, then finally after a day wouldnt start

If the air pump system is setting a fault, then the check valve is probably bad. If it is not addressed, eventually exhaust gases can run back through the air hose to the air filter housing and destroy the MAF sensor, causing these types of problems.

The fuel pump also fails and is a more likely cause of the stalling, and it wont set a code.

I had the same problem with the 2000 v70 XC I bought in Dec. 08. I replaced the battery, then the antenna ring (around ignition; part of the immobilizer system), and bought new keys as sometimes the chips in them do go bad. Also, if you have a key for another car with an immobilizer system on the same keyring, take it off. The multiple signals can confuse the immobilizer system. I think the antenna ring may have been one issue as, consistent with what repairpal stated, I got a crank and the engined turned over for about a second or 2 one time and then it died. The antenna ring (and the new keys) were relatively inexpensive. That worked for about a month and then I got no crank at all.  I had the starter replaced, but in hindsight I think that may have not been the problem.  I think the problem was the starter not getting juice. The starter was a very expensive solution. About 2 weeks after having the starter replaced, it wouldn't crank again.  I took it to a Volvo dealership and gave them the history. They found a corroded wire near the starter and, at least until now, that seems to have done the trick. Labor on the wire was about $100 at the dealer. Searching Volvo forums for those who have had a similar problem, I have found that others have had the "bad wire" problem.  If you are told to replace the starter by your mechanic, my advice to anyone having this problem is to have check to make sure the starter is getting juice before replacing the starter as replacing the starter (parts and labor) cost me about $650-$700.  If they find that the starter is not getting juice, they can check for wire corrision starting at the starter and working their way back.

It could be a number of things. Fuel Flow problem, or electrical apparatus heats up and works inefficiently. You could start from the cheaper, less strainous solutions, in this order: Change Fuel Filter, and clean Nozzles. Fuel Pump, Air Mass Meter.

SOURCE: Car won't start

If there is a blinking car icon with an "X" over it. This icon means the Immobilizer has been activated and hence won't allow the car to start. It could be due to a bad SCU, Start Control Unit. The SCU is actually the ignition switch on these cars.
Most of the time it's triggered by the anti-theft system..You can try this trick i learned that the dealers won't tell you...try locking and unlocking of the doors five times with the remote to reset the immobilizer and see if this helps.
Good luck...i hope this helps...please take a minute to rate me a fixya.

SOURCE: air conditioning works when car first starts up

It sounds like your cooling fans are not working.Need to check the cooling fan fuses,and the cooling fan relays.There is also a high side switch mounted somewhere on the high side of the ac system that cuts the fans on,or kicks them up on high speed when the ac system gets to high on the high side of the system.This switch may also cut the compressor off.I would check the fuses and relays for these fans first,this is more likely the problem.Is the car running normal temperature? If not the fans may not be running at all.Have them checked.The fan or fans may be bad them selfs.If I can be any more help,let me know.>>[email protected]
