    No start!! fuel pouring under intake

    Hey guys, I shut off my e23 when I was driving sue to the temp gauge going up, as I tried starting back up I got nothing and have been getting nowhere since, the symptoms are the fuel is pouring out from underneatg the breather on the intake. Can’t seem to figure this out, before this issue I changed the fuel pump cold start valve, and verified that the ecu has no damage, really wanna get it back on the road, please help guys!!

    Yes, your thread has been moved. What year is your e23?

    My assumption after running some more tests, bearing in mind I’ve changed the 2 reference sensors for the flywheel, checked for spark and was unsuccessful, I’m thinking it could be the pin on the flywheel has maybe came off, my next move will be to manually turn the engine and see if it is on.

    Have you checked or replaced your main relay? Some of them use two sets of contacts, if one set fails you can loose spark but not fuel. This also happens if the wrong type of relay is used. Took me a while to figure this out on my project car as it had the wrong relay.
