Volvo has had a lot of trouble with ABS control units. Yours will most likely need to be replaced. You can either replace it with an exchange unit from a Volvo parts supplier or send yours to BBA reman. in MA for repair.

Don't know your engine size so pick the correct one for your motor:

2.3L 4-Cylinder Engines Firing Order: 1–3–4–2 Distributor Rotation: Clockwise

2.8L 6-Cylinder Engine Firing Order: 1–6–3–5–2–4 Distributor Rotation: Clockwise

2.9L 6-Cylinder Engines Firing Order: 1–5–3–6–2–4 Distributorless Ignition

Yes, if the pcv valve is clogged or not properly connected to the air inlet, it can allow more blowby. However, if there a lot of miles on the engine, it might be time for new piston rings. Run a compression test on all cylinders.

any check engine lights/codes?, maybe that oil sprayed onto a connector somewhere and caused an issue, most the time the connectors are sealed but if one was broken or old and cracked it could let oil in between the contacts and cause an issue.
im not going to tell you its a cam or crank sensor with knowing for sure you are the one that needs to do that diagnostic, sorry..
anyways that's an intricate problem for sure and many things need to be checked before condemning one part or another.
i have seen coils fried from excessive cranking under no start conditions, they can be ohmed out to see if they are bad, disconnect them and remove them from the car and ohm them out with a digital meter and compare it to spec, ohm out the primary and secondary windings . the crank sensor most likely gets a signal from a reluctor wheel which is a piece of metal behind the crank with pieces cut out of it, clean it off and make sure the crank sensor face is clean too.
i would go in that order, dont condemn a part just because you think its bad. next with the main relay it can be checked or "jumped" but i dont want to suggest how because it could fry something electrical if done improperly, about the best advice i could give with the main relay is try to get it out smell it to see if you smell any burnt smells, and last open it up and check solder joints for cracks with a magnifying glass. if you see any cracks have someone thats good with a soldering iron fill the cracks and go from there.
good luck and any feedback will help in your journey to fix this thing.
dont get discouraged and once again if it has a code start there, even if its a history code or pending

You will need a torx bit set, I am not sure of the size, but all the torx screws in the removal should be the same size. First, removed the panel under the glove box, then remove the glove box itself. The you will see the SRS passenger air bag plate, which is held on by 3 nuts, 13mm if I remember right. Then take that out. Now you will see the blower to the right when looking through the opening in the glove box. To the left you will a black flat plug which is plugged into the back of the rectangular shaped Resistor; it has an ear on it where there is a screw attaching the resistor to the ventilation duct. Simply unplug the resistor and remove screw. Installation is reverse of removal.

Your wiper arm is worn out. You need to buy a new one. Make sure you get a Volvo OEM replacement as the after market ones are junk. The springs wear out after a while resulting in loss of contact with the windshield.

This is a common problem on these older Volvos. Try pulling up on the hood (after hitting the hood release in the car) and then push the latch in and then lift up again while pulling the latch out.

Sounds like the electric motor is going bad.

1996 Volvo 850 | Answered on Apr 07, 2017

could be from
bad injectors
air in fuel
leakdown from problem pressure regulator valve
glo-plugs not operating
pump not producing the desired pressure
at this point I suspect that injectors/ pump need reconditioning as the unit is 21 years old probably never having either serviced
take it to an accredited diesel specialist shop for a proper diagnosis and quote

Look at this as a guess and please leave me a thumbs up if I get lucky but NOT a thumbs down if I don't have the right answer OK? I can't afford a bad mark for trying to help someone.
The smoke you saw may have been only the fuse burnning out. This is not a serious thing unless it continues to blow more fuses. We now need to get you under the dash and locate the fuse box. Some boxes are covered by a flap that blends in with the dash so if you don't see the box by looking under the left hand driver side then look for that flap and pull down or off or what ever. Once you find the box you should see a diagram on the front of the cover or behind the cover. You will be looking for one marked instrument panel. But in your case with the smoke you need to check every single fuse. that one fuse may have taken more then one with it. Pull each one 1 at a time and look to see if the wire inside it is melted in the center or blackend. If the wire is good it will look clean and the wire will be one complete wire with an arch to it. That is unless yours are the old glass type but same therory. the wire inside must be complete.
Make sure the key is out of the ignition before replacing the bad one/ones. Replace with only the same amp fuse that came out of it. Mark and remeber where the bad fuse was. After you have checked all the fuses then with your flashlight look at the surrounding wiring for any melted wires under that area of the dash and under where you saw the smoke come from. If you find melted wire under there then remove the bad fuse you replaced until you can get good wire spliced into the melted wire.
If you do not see any melted wire then come up and turn the ignition switch to on and watch and listen for another pop. See if the dash lights come back on if you don't see smoke or hear the pop. If they do then you should be good to go. Fingers crossed at my end. Remember me in your kind works, Raz

The stock fuel pump pressure should be around 44 PSI and it should hold that pressure for quite a while. If it bleeds of quickly after the pump stops (key off) it indicates a bad check valve

Fuel pump fuse or relay.

Hey Kolby!

Sounds like you've got an issue with your alarm module, causing the immobilizer to activate (also known as a "start inhibitor"). I'm not sure what type of alarm you've got, but this will probably help you find out if there is something wrong with it:

There is a panel with relays on it behind the dash. At the bottom of the steering column, by the drivers feet, there is a panel. Remove it to get access to the relay panel (just a couple of torx screws, no breakable clips as far as I can remember). Remove the "double size" relay (probably marked 210-211). Put a wire between the terminals 50E and 50F. This will hotwire the immobilizer and make sure that it always activates when turning the key.

Drive around with the wire in place instead of the relay for a while to see if this helps. If it does you'll know that the problem is related to the alarm system. Keep in mind that you will be without alarm and therefore probably also without remote central locking while doing this.
Make sure that the wire is connected firmly enough so it doesn't come loose. You can also put a fuse on it if it makes you sleep better at night ;)

Good luck!

You may have a bad positive battery cable, with a digital volt meter you can test and see if you are getting 12 volts through the entire cable or at least to the cable junction block, in or by fuse relay center, then check cable from there to starter. you should also check the main, battery, power, fuses and relays, usually in the under hood relay center(fuse box)

Yes. Call a dealer.  If they tell you that you have to come in person or want to charge you then call another.  Even search for dealers over the internet.  Most will give it to you over the phone, a smaller portion will want to either charge or make you come in person.  Again, if that happens just call another dealer.  If the radio is original, you can just give them the VIN.  If you suspect it isn't or if the code they give you doesn't work then you need to pull the radio and gave them the serial number on it.
