Getting my new Volvo running

Hey guys, my name is David new to the whole Volvo community, I just purchased a 1979 Volvo 242 with the intention of turning it into a big project but my first goal is getting it running so I don't have to push it everywhere. As of right now when I crack the engine fuel pours out of the intake hose area.

With some Google I read that this may be the FPR or Injectors. I am not familiar with the Kjet system at all and if you guys could lend your wisdom on where to begin it would be greatly appreciated.

Well, the only real problem you need to address is the fuel gushing forth.

Look closely at where it is leaking from; see the failed part?

Note what it is, look it up on IPD.com as to price and availability, and buy it, either online or locally.

Then once the flood stops, take a closer look at what you bought.

Congrats on the new Volvo and welcome to the forum.

Start by understanding the Bosch CISystem. Volvo published what we refer to as Greenbooks covering every aspect of the cars. Here is a link to the one covering the K-jet system:

That refers to tools specific to the system and some info on that subject plus lots of other links are here:

Big learning curve ahead of you. Pictorials on lots of common repairs are found in this treasure chest thanks to Art:

Another excellent resource is this site's 'Article Composition' forum. Hundreds of 'how to' articles.

I wasn't really rying to be insulting: the guy seems not to know much about cars, so his learning curve is near ground zero: he really needs to LOOK at the engine, see where it is leaking from, repair it, then see what's going on.

I'm sure the source of the leak will be obvious.

No way to know what the source of the leak could be based on his minimalist description.

Thanks for the warm welcome! Those green books are awesome, no other car I have had has had resources like that.

Thanks for all the links Testpoint, I wasn't able to see any of the Article Composition threads before for some reason!

Mr. V, no insult taken, I was pretty sparse in my description because I am not familiar with these kinds of motors at all. The source of the leak is what I would think is the throttle body on any other car just not familiar with the layout on this engine yet. I am going off of what the previous owner described to me until later today when I get a new car battery and replicate the issue myself.

You have to set the forum view dates (in each child forum) to show not just what was posted today... it took me forever to figure this out.

Perhaps a little more information would help us. Has the car sat up for awhile? Run recently? It is common for folks joining the forum trying to get cars running that have not for months if not years. Starting on one of those is a little different than fixing a leak.

Previous Owner stated that the car broke down near the end of summer. I've checked the fuel lines and such for rot from sitting fuel but looked clean. I will be draining fuel later today just to be safe so it doesn't cause damage while it sits there and I work, only filling as I go.

Fcpeuro.com has a bunch of parts too

If you can take a picture or video of the fuel pouring out, I'm sure many people on this forum will be able to identify the issue with greater specificity.

Okay quick update and some more details.

I went and replaced the cold start injector with another one that the previous owner had provided just in case since it seemed like a good place to start. Tried to start the car initially with little success, I could tell the engine was starting to turn over but seemed like it wasn't combustion just wasn't happening.

After a couple tries it was getting worse so I went and took a look at the leak location, seems like the leak is actually coming from the Airflow Sensor from what I understood from the diagrams.

I took apart distributor cap and made sure it and the wires were maintained, there was some corrosion under the distributor cap connections so I hit them with a wire brush to clean them up and the ignition rotor to be safe too.

I was halfway trying to take the Airflow Sensor off to replace it with another extra that came with the car when I decided to try another run and see if anything changed before I tried multiple things at once. Once I had the cap and wires back on correctly I made another attempt of getting the car to turn over.

This attempt I was able to get the car to turn over for a couple seconds before there was a pop that sounded like a vacuum tube popping off. I was able to record this part if you think I heard wrong please let me know https://youtu.be/kkEjXpE6vgg

Here is a picture of where the fuel is dripping out of as well in case I am wrong with my assessment.

My plan tomorrow is replace all vacuum tubing and re-secure everything that is secured with zip-ties with hose clamps instead, unless anyone thinks I am missing the mark.

Sorry if past descriptions weren't great I was going off of other peoples experiences.

Lol I posted all that exactly one minute after your post. Tried to be as detailed as I could.

The plunger in the fuel distributor is the likely source of your leak. It's the only place fuel can leak directly into the air flow meter. If that's the case, it can't be repaired. It has to be replaced.

I have a replacement from the junk yard any way to test that it is good before I install it?

No. You need to pressurize the fuel distributor, and it needs to be attached to the air flow meter or the plunger will come out.

Alright I guess that's going on tomorrow, the lines coming out of my replacement unit have the shielding cracked well that cause issues? I can post images in the morning.

Yesterday I started going off some advice of a few people including yours so I tested pump and had no issues at fuel pump, so I proceeded to take apart the engine on the intake side check all hoses, lines, and injectors along the way. I found a few issues with bad securing but was able to get down to the K-Jet which I replaced with an extra that came with the car.

It seems the K-Jet that was installed on the car was a Porsche unit. You can see them in the image. The one with no lines being the one I removed and the one with lines the one I installed.

After putting everything back together replacing a few injectors, and hose clamps along the way, I started the car. I did not take a video that time but the car started easily with no struggle. After a few seconds there was some smoke from rear and transmission area but no smell, just to be safe I pulled the car out of the shop. After about 30 seconds the smoke stopped and the car was running fine. I drove the car around the parking lot to make sure check everything was fine.

It drove well but when I got back to shop I put it in reverse and the car lost power and stopped. I tried starting it again with no luck afterward.

Today I went back looked for any leaks or anything I may have missed found a couple fixed them and was able to start the car again but only for about a minute this time until it lost power and shut off again when I put it drive and tried to move.

I spent the last few hours looking for anything I may have missed the videos below are what I have been able to get to.
