WHat do you mean release the fuel line?
By releasing the fuel line where it enters the fuel distributor, just a fraction of a turn, the engine runs. But obviously this allows fuel to sprayer out of the joint.
Sounds like the mixture is way off, have you checked for large vacuum leaks or to see if the airflow plate is binding? Since you said fuel distributor I'm assuming this is a K-jet car?
Cannot find any air leaks, now do you check the airflow plate? Regards from England
Have you established if:
1) the ignition system is creating a spark at the plugs and 2) whether or not fuel is getting into the cylinders?Test (1) by using a spark spark plug. Ground it (I sometimes use a jumpoer cable to establish a good ground) and connect a plug wire from any cylinder (or the coil lead) to it. Have someone crank the moor while you watch for a good spark in the plug's gap.
Test (2) by cranking for a bit, then remove the plugs and check for gas on them.
Once you get that far you will know where to look. Otherwise you can spend teo weeks hunting down an ignition problem when it could be a bad fuel pump, or vice versa. etc...
Did I mention Air mass Meter?
The car does have OBD- did you try to read the codes?

Are you sure it's the fuel line and not the return line you are releasing?
I just think that maybe a blocked return line could give overpressure resulting in starting problems.

Thanks to you all for your replies.
I have a good spark and fuel is getting to the plugs.
I will check that i am looking at the correct side of the fuel inlet/outlet. The diagnostic check reveals "no fault found"
