ok so i was on my way to my brothers wedding and my 1996 volvo 850 glt just died. after the wedding i went back and checked to see if the fuel pump went out by checking pressure on the fuel rail and that was fine but i tried to get the spark plug wires to jump from a screwdriver to the block and there was nothing. anybody have any suggestions on what it is? i think it may be the ignition coil.

 

Check the plug for the cam sensor.
You also need to check for injector pulse.

 

how do i check those?

 

Well see if you can find a noid light to borrow to check the injector pulse.

The cam sensor is on the back of the head. The intake cam has the dist. cap on the back of it. The exhaust cam has the sensor on it. Follow the wire from the sensor to the plug. See if the plug fell apart and came unplugged.

 

to check the injector pulse what do you do?
sorry i keep asking questions about some basic stuff, i just need to make sure what to do because i need to diagnose whats wrong with my car and get it going asap.

 

You need to find a noid light and plug it into one of the injector plugs. Then crank the car over and watch for the light to flash.

 

alright thanks man, youve really helped me out. and you know alot about volvos lol

 

Hopefully it is pretty easy to figure it out.

 

yeah i hope. im really not looking foward to buying a new coil with the last bit of money ive got.

 

I doubt it is the coil. I have yet to see a 850 coil fail.

 

this car is 14 years old...

 

to get to check the fuel injector pulse do you have to take off the fuel rail?

 

No the top cover on the rail just comes off. Pull on it towards the front if the car then remove it. Unplug one of the injectors and put the light in and you are ready to test.

 

thanks man, if the light doesnt come on what could be the problem?

 

Can sensor or the one relay under the plastic cover over the radiator.

 

thanks man.

 

Your welcome.
