Had a previous thread starting in 2022 about my 73 1.7 standard D-Jet running way too rich and flooding to the point where it wouldn't start. It's been an ongoing issue. I've had a go. 2 garages have had a go. I'm at the point where I'm beginning to lose hope.
A recap. Bought the car 2021, had a problem with intermittent flooding. So far have: Checked MPS - holding vacuum. Replaced CHT sensor and tested. Working when flooded. Replaced fuel pump and tested pressure. Replaced all vacuum hoses and tested for leaks. Valves set and rechecked. New 123 distributor. New injectors. Each time I think I've cracked it and it runs and drives - sometimes for a month or so. Then I'll go to start it and it'll flood again to the point where it contaminates the oil. I feel like I've never managed to get to the bottom of the problem. Just keep replacing parts. Thinking maybe a return line that intermittently blocks? I'm kind of at a loss. |

Thanks so much for the suggestions. I’ve been through the list of part numbers and can confirm they are correct for a 73 1.7 so no parts have been mismatched previously. The MPS hasn’t previously been opened and I had hoped the 123 would mate sure the spark was good and consistent but I’ll double check this and leads (which should also have been new).
Thanks so much for the kind offer of a loan of an ecu and if I was stateside I would gladly take you up on it, but I’m in the UK. I’ll try and source ecu and mps to swap and see. If it does come to rebuilding mps is there a specialist who can do this? |
