hot start problems
I have a 911E sportsmatic 1969 my problem is not starting when hot I have got it down to a fuel injection problem no fuel being sent to the injectors it seems to be shut off at the bosch mechanical fuel injection pump, there is plenty of fuel/fuel pressure from the fuel pump to the fuel injection pump, this injector pump has the two solenoids fitted an inrichment and a shut off which I have checked and by-passed as not the problem, it seems that if I get the engine up to temperature then stop and start its OK but if I leave it for a half to one hour it will not start no fuel from the injection unit to the injectors but plenty from the fuel pump, on checking the thermostat bolted on the back of the injection pump it seems there could be a shim of 2.11 mm thickness missing between the too although the gasket is present, can any body confirm if this shim should be present on my injection pump and could this cause my problem,any help please, regards,Tony,Totnes,Devon,UK.

Tony,

I notice that your thread didn't get much love! If you are still having problems you might want to look here:

Ultimate MFI Resources Thread

or here:

MFI Message Board Index

and especially here:

Understanding and dialing-in the MFI system for the first time. Detailed thread about setting up and troubleshooting an MFI system. Also discusses Hot Start issues.

I am trying to get together all MFI resources in one location so that we can all benefit. If you can contribute, please do and ask your friends to do the same!
