Rekord E2 2.2 project Posted October 18 Share Posted October 18 Hello everyone, my girlfriend and i bought an old opel rekord E2 2.2i from the 1986 with 102.000 km, we are trying to bring it back to life, but the major problem we are having is with the engine, when I press the throttle pedal it revs up and then dies, and lots of black smoke go out the exhaust. We cleaned the fuel tank, put a new fuel filter and we don't know what else to do. Here is a video of the engine diying: https://drive.google.com/file/d/1_c9RPu7PlvIysCXSSNc6SfgVcyiMDaLb/view?usp=sharing Thank you very much. sorry for my bad english, its not my first language.

Jessopia74 Posted October 18 Share Posted October 18 (edited) sorry can't view the vid file from work. But sounds like over fueling. Did you at any point remove the pipes that go onto the injection rail? It could be difficult to diagnosis over the Internet, ofc depending on what tools you have available and what tasks you are comfortable doing Edited October 18 by Jessopia74 1 Quote Link to comment Share on other sites More sharing options...
Sutty2006 Posted October 18 Share Posted October 18 First things first, have you serviced it recently? new spark plugs, HT leads, distributor cap and rotor arm? Start there first, because you could be loosing spark under load with a broken part listed above. Can we have more pictures of your Rekord? I have one of those I use regular 👌 1 Quote Link to comment Share on other sites More sharing options...

It could be difficult to diagnosis over the Internet, ofc depending on what tools you have available and what tasks you are comfortable doing One injector and some pipes were leaking so we had to replace the seals of the injector and those pipes. I have a wide range of tools thanks to the guys i'm sharing the shop and i'm comfortable with learning and doing anything. 48 minutes ago, Sutty2006 said: First things first, have you serviced it recently? new spark plugs, HT leads, distributor cap and rotor arm?

Sutty2006 Posted October 18 Share Posted October 18 My 2.2i had not ran in 15 years. The first job I did was a compression test on all cylinders. 150 psi on all. Then new plugs, leads and service items. After replacing all the fuel pipes and new petrol, it ran perfectly. 1 1 Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted October 18 Share Posted October 18 as above plus make sure that the temperature sensor is plugged in and also ensure that you have got the flow and return pipes the correct way round. flow from tank through filter and pump and to the injector rail. via the little "T" connector and return to tank from pressure regulator centre pipe stub. ( in case you had mixed anything up ) 2 hours ago, Sutty2006 said: First things first, have you serviced it recently? new spark plugs, HT leads, distributor cap and rotor arm?

We checked the ignition system today all ok, so I guess it's going with a rich mixture, maybe te temp. Sensor, I read somewhere that there is a vacum system that controls the injection, any idea about that system? 🥲 Quote Link to comment Share on other sites More sharing options...
Jessopia74 Posted October 19 Share Posted October 19 Vacuum controls the fuel pressure regulator, changes the fuel rail pressure a small amount when the pressure in the plenum changes, so that the Injection pressure is a constant value over the plenum internal pressure, it should be 2.5Bar. I wonder if your replacement pump is over whelming the weedy little regulator on the injection pipework. However, you still need to check the fuel pipework orientation is correct IMO and rail pressure. Do basics first! Quote Link to comment Share on other sites More sharing options...

However, you still need to check the fuel pipework orientation is correct IMO and rail pressure. Do basics first! In theory the pump is giving 3 bars, do you think it's over wheeling the pressure regulator? And the pipes are correct, pump to filter, filter to the T junction and then from the rails to the pressure regulator and from the regulator to the return. I thinking of buying another temperature sensor to try if it's that, they are fairly cheap. Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted October 20 Share Posted October 20 its easy to check the temp sensor. on the 2.2 its 2 sensors built into one unit. each pin should have a very similar if not identical resistance to earth. ( unlike 2 litre sensors which are only one sensor and cannot be interchanged !) ive never actually seen one fail but obviously anything is possible. check you have a good fuel return back to the tank .ie not blocked.

Rekord E2 2.2 project Posted October 20 Author Share Posted October 20 One important thing to note is that, if I disconnect the air flow meter, it idles smoothly at 2600 rpm but dies if I press the throttle, ones I connect it the car dies again 😅🥲 Quote Link to comment Share on other sites More sharing options...
hoobby Posted October 20 Share Posted October 20 Did notice on your video the engine breather looks like it's not attached to anything should be in the side of the throttle body otherwise you'll draw unmetered air into the throttle body or is it blanked off?. 2 Quote Link to comment Share on other sites More sharing options...

It wasn't blanked of when I bought the car, but I tried the engine with it blanked and there was no luck. Quote Link to comment Share on other sites More sharing options...
Rick H Posted October 21 Share Posted October 21 Check your spark plug colours to see if they're all the same, pics will help. I think I hear an air leak. Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted October 21 Share Posted October 21 (edited) did you check you have a good flow return back to the tank . if this was blocked or the regulator was stuck then you would have very high fuel pressure to the injectors . as mentioned. black smoke suggests over fuelling and this is controlled in various ways ( assuming the ecu is not faulty) too much fuel pressure from hoses piped up wrong way or faulty or stuck pressure regulator stuck injector wrong temperature reading from sensor or wiring faulty or stuck air flow meter / internal flap stuck obvoiusly air leaks anywhere wont help . breather, servo,idle air valve. but shouldnt cause overfuelling !
