[FirstDotLast]

Hey all,

I recently did a bunch of engine out work on my 1986 930 and after putting everything back in, it turns over and cranks but won’t run.

When the engine was out, the majority of the fuel system was overhauled, fuel tank was drained, all the fuel lines, fuel pump, fuel filter, etc were replaced and were tested before the engine went back in the car for leaks and pressure. Fuel pumps work great. Also some vacuum leaks that were present have been fixed.

Now when starting the car, the car cranks but won’t start and the cylinders flood. Gasoline starts dripping out of the exhaust joints.

If it’s flooded, and I remove the fuel pump relays, then start, the car runs for a second off of the residual fuel then cuts out of course.

Here’s what I checked so far:
- timing is correct and at Z1 mark the distributor rotor is pointing at the notch
- removed air box and the mixture plate moves up and down smoothly, no sticking that I can tell
- plugged the cold start injector line and same condition, too much fuel
- pulled all spark plugs and they are all at least a little bit wet which tells me it’s before the injectors? Unlikely all 6 injectors are bad

Could this be the mixture being way off? That seems unlikely as it shouldn’t have changed but I did fix all the vacuum leaks. Could it be bad plugs? Also seems somewhat unlikely. Any other ideas of where to look? Why is it getting so much fuel/not combusting it? Thanks!
