Can anyone confirm that this is the correct order for the cap and wires.

It is different from what is in the Haynes.

Car is a 1996 850 turbo.

Thanks.

 

Did you take off the plugs and forget where they go?

 

haynes is wrong, that link is right.

haynes is off by one plug.

 

I followed link when I did mine

 

Distributor cap is numbered and longest cable is No 1, shortest is No 5

 

I have never done the job and was researching it. And noticed the discrepancy between the Haynes and Bay13. Just curious what you all thought. I will follow Bay13. Hope that fixes my misfire issue. I have already put the volvo plugs in -- still get the misfire.

I just checked the bosch cap and sure enough they are numbered and it corresponds to the Bay13 pic.

 

I put the new cap on last night. Hopefully that will fix the misfire. One of the problems is that the misfire is not consistent so it will take time to figure if it is fixed. When I started the job i noticed there was not much room so I took off the turbo pipe, and moved the air filter box out of the way -- including the bottom half that snaps onto the frame.

When I finally got to removing the three screws I noticed something... the bottom screw on the cap was not screwed in at all. My theory is that the last owner tried to replace the cap and since there was not much room just left the bottom fastener undone.

It seems that that could be the cause of the misfire because it seems to me that that go alter the flow of electricity.

I guess only time will tell. If that does not fix problem next up is bougicord wires.

 

Hopefully it is. Good luck!

 

WHOOHOOO... thank you! I love the Internet and its marvelous Forums!!!

 

So, I am helping a friend of mine who has a '95 850 Turbo sedan. His car has been spontaneously dying on him. He pulled the plugs and they are gas fouled. I suspect that the injectors are bad as I had a similar problem with an old BMW I had years ago.

While pulling the plugs he damaged one of the plug leads. He replaced the wires, but did not pay proper attention to wire order. Now the car won't start at all and I suspect that the wires are not in the right order on the distributor cap.

I have reviewed this thread (and some others I tracked down via Google) and there are several competing descriptions of the proper order. The Volvospeed link at the beginning of this thread is no good.

Two of the outputs on the distributor cap are taller than the others (left side of the distributor @ about 9 and 11 o'clock). What I am hoping is that one of you can give me the correct wire order referencing one of these points.

Thanks

Danny

VolvoSpeed had to redo some things on their site which broke a lot of links.

Other than that, random stalls are usually caused by a bad fuel pump relay. So do check fuel pressure.

 

Thanks. The problem is not really random stalls. He has had it quit on him twice recently when it was idling in the driveway and he was scraping the snow off the windows. Both times pulling the plugs showed them to be gas fouled. The first time cleaning the plugs cleared it up. The second time lead to the damaged plug wire end and where we are today.

Excess fuel pressure is a possibility, but I think the problem is more likely to be worn out injectors. I had almost the identical problem several years ago with an '86 BMW and new injectors cleared it right up.

Before I can check on the potential injector issue however we need to be able to start the car.

 

PERFECT! that was exactly what I needed. Thank you!

I love owner forums. I belong to several for various cars and motorcycles I own/have owned. They never fail to be a treasure trove of information.

 

The problem with these cars are rarely due to excessive pressure, it's usually lack of pressure when the relay shuts down the fuel pump intermittantly. If he is having other stalling issues due to lack of air he may have a MAF problem or idle control problem.

Have you guys pulled codes?

 

If you get beyond a fuel pressure regulator problem, or coolant temp sensor (I had a problem with this - sensor was failing ONLY at approximately 90-120F causing me to flood while warming up), or other management issue (MAF and O2 sensor, etc) and decide to do something with the injectors - I highly recommend Mr Injector. Quick service and before and after reports on flow rate and spray pattern.

Not to mention, it is far far cheaper than new injectors.

 

bankerdanny,

I'm happy to read that the link was helpful. I too have been helped out by many others on auto forums and I'm glad I could 'pay it forward'.
