Hey,

I just bought a 242dl yesterday under the pretense that it was not running. It turns over but thats it. I've got spark and the cat isn't plugged because I'm getting some kind gas out of the tail pipe. I was able to pull the number one injector and its not squirting gas. I couldn't get the other injectors to come out (the first one just kinda came out when i was trying to pull the hose from it). Is there anyway i could check to see if the fuel is getting to the injectors? Also where is the fuel pump relay located, as I've heard that these are common in no-start scenarios. Thanks for all. Adam.

The injector just pulled out...? That can't be good. It should be secured by a screw and a retainer.

To check the injectors you need all of them out of the head with the supply lines still attached. You also need to pull the rubber boot which connects the air flow sensor to the throttle. And you will need to run the fuel pump without starting the engine. It would help to have an assistant.

There should be a cap screw right next to each injector. Remove them and the retainers and pull the injectors. Remove the rubber boot (roughly conical in shape). It has hose type clamps. At some point you will be needing to lift the air flow plate and there's not much to grab ahold of except the screw which fastens it to a lever. I have taken a loop of string and lifted the plate enough to slip the string around the plate so that it can be lifted easily when the time comes. Be careful not to bend that lever. You won't have to lift the plate much.

Take the injectors and put them into a large jar. This is a pain because ther's not much play in the fuel lines. Last time I did this I put one in the jar and the other three in another jar because I was checking the spray pattern and it was just easier to isolate one and then move to the next.

Now take a jumper wire and connect the #5 and #7 fuses. This runs the fuel pump. Ignition does not need to be on. You will hear the fuel pump if it is working.

When the pump is running lift the air flow sensor plate and you should get fuel spraying out of all the injectors. Spray pattern should be conical. Anything else and the injector is dirty or bad.

Check your injector seals while you're at it. If they're pliable they're okay. If they're brittle, cracked or broken in pieces then, obviously, you should replace them. There's one on the injector and another one on the insert that fits into the head. The insert may have come out with the injector when you pulled it or it may still be in the head.

Take all saftey precautions for working around flammable liquids.
Sorry to be wordy and condescending. I don't know how familiar you are with any of this.

You don't have to worry about being wordy or condescending, I apperciate any help you can afford me. I have a 1800es so i'm fairly familiar with d-jet but this is my first venture into k-jet. Looks like its gonna be fun... especially since they were able to fit everything UNDER the intake manifold. Thanks again. Adam.

Above your left knee, when your sitting in the drivers seat, its usually green, sometimes black, sometimes red, about 1"x2" x2". Also check fuses 5, 7, 13.

Most "virgin" volvo's have it neatly clipped in place, all of mine I leave hanging down, as it seems i'm always having problems with them.

Do a search for "no start" or "fuel pump relay" in the archives, lots of good info.

Hello again. Checked the fuel pump relay and it emits two clicks when the ignition is turned on. I was looking over the engine bay I found a few things of interest. there is a vacuum hose by the intake manifold disconnected from i don't know where but it leads to the charcoal canister in front of the driver's side wheel well, the other hose coming from the canister is cracked as well. also there is a small diameter hose coming from a nipple on the middle of the intake manifold that looks like it should go to something under it but it is also disconneted. Could this have anything to do with a no start situation. I also removed the fuel pump side connection of the fuel filter. When I broke the seal i could hear it depressurize but there wasn't any fuel squirt when I got it off. I also tried cranking the car with the fuel filter disconnected and only a very small amount of fuel came out. Thanks for all. Adam.

Thanks Bruce. I found the fuel pump relay. It wasn't clipped in place and looked fairly new. I also checked the fuses ( I went ahead and cleaned the contacts on all the fuses and reinstalled them with dialectic grease ) they seemed alright. to check the fuel pump relay i must listen for it to click correct? Thanks for all. Adam.
