My question is what the cause of the obd1 port in bmw car 740i 20 pins wont read the diagnostic tool?someone please give some advice...

OBD1 is basic information 'your vehicle needs looking at'. OBD11 is the one with the codes. With earlier OBD1, dealerships could use their own diagnostic equipment as codes were pertinent to one make. OBD11 made codes more universal.

How do I access the trouble codes on a 1995 Mercury Grand Marquis without a scan tool?

You can access them by going to the link, some late 1995 vehicles were OBD2, then you would have a diagnostic connector under the dash below the steering wheel, otherwise you do it under the hood (OBD1). FORD 1983 1995 OBD1 Decoder

How to test the obd codes

What is year--make--model? Generally 94 model year and older is obd1. 96 and newer is obd2, generally. 95 can be a cross-over year and could have a hybrid diagnostic connector.

Usually with obd2, you need an obd2 code reader. OBD1 you should be able to access some codes, yourself, w/o a code reader. Different makes can have different procedures for accessing codes/obd1.

Engine cranks but takes long time to start and malfunctions

could be a head gasket along with a few hundred other things..
With more details, we might be able to better assist.
How long has car sat without running?
What happened the last time it was running - engine overheat? ran engine while low on oil/ coolant?
How many miles? any prior (recent) work done? Have you read the OBD1 Codes? (obd1 codes are vehicle specific.,. (so that would be a dealer for this year auto)
