Hi, I have recently put a running E220 petrol coupe engine into a Cabriolet and have had some issues with the cabby now choking it self after 60 seconds or so and struggling to now even start, I have checked all vac pipes and checked the sender unit which had abit of corrosion round it. The fuel pump etc is working fine no leaks or anything, I put £25 of fuel in there today and the needle kept on moving even tho it choked itself after 60 seconds - would it be worth changing the fuel tank filter? The OVP has been changed out of another 320 I own and the fuel pump relay but still not change? Any ideas what it could be or what else I could try whilst at home with the covid 19 pandemic going on?

Thanks in advance

Raj

Welcome Rajan124,

Although your fuel pump is working,
have you checked for fuel pressure/ fuel flow at the rail?
Yes, it would be a good idea to change out the ff.

Hi khomer2 thanks and thanks for replying so fast. I haven't checked that I shall try that tomorrow and I'm going to order the ff tomorrow. I didn't think it the ff normally needs to be changed on the Petrols. Looking on YouTube it's mainly the diesel engines but always good to check I suppose. Thanks again

Not 100% familiar with your model. On the rail, there should be a schrader valve (near the front of the engine)
Should be similar for all MBs

OR




EDIT:
I also recommend you scan for codes and post here.

Rajan124,
You need to post on the thread, not in conversation.
Follow post#5, you're getting ahead of yourself.

Hi I have recently had the car checked and it needed to be re coded as the ECU came from a coupé to a cabriolet so the car now runs however a gear adjustment is needed but that's minor. I will get the codes soon and post here. Thanks for your help all👍🏽
I will also attach the document with the diagnostic information.

These are the diagnostic pdf file notes. Can be found on Google.
