Hi looking for some help on my 89 escort cab 1.6 cvh mfi. Took on as a project and to learn and got it through its mot but still have a load more problems / work to be done.

It starts up then cuts out straight away , when i put my foot on the accelerator it bogs out worse but if i keep turning the key about 10-15 times it starts up then once its warm runs great and starts first time.
I have done or tried -fuel distributor ( i swapped that no difference ) the cold start valve (was black) warm up regulator ( blocked green gunk ).
What else could i try? Thanks.
