Old owner made this job, i think the job is very good finished.
Also, the transmision was empty on dipstick the other day. So, the leak must be ATF fluid dexron III. Anyway, I will check this tonight. Thanks you again!.
One of my banks are not working (or working well).
Boths have spark and injectors pulse, but one of my fuel pressure regulators are broken (passenger side location), and a lot of fuel are going to air intake directly.
I bought today, and I will test into few hours.
When I touch air intakes from both banks, the bank of passenger side is cold, and the driver side is hot. The FPR passeger side is that is losing fuel. I assume this fuel rail dont have enough pressure to make injectors works, so I have here the problem (when removing the FPR vacuum pipe to air intake, there is a lot of fuel going out from FPR).
If I disconnect the driver side MAF, engine dont change anything. If I disconnect the passenger side MAF, engine dies, because only my driver bank side is the unique bank working. (I know air intake from passenger side goes to driver bank and viceversa).
No EML light problem, I can drive the car but high fuel smell.
This was my first time driving the E32 750.
I will update it today after replace the FPR broken.
Well, engine run perfectly now!.
I replace this fuel pressure regulator, and...all sounds ok now!
I buy the S.I.D.A.T. FPR with ref number: 89.010 and bar code: 8033208078719, with another reference (sounds like pierburg...) 7 52 050 10 01.
When I bought it, I ask for the FPR compatible with Bosch: 0 280 160 697.
It cost 45€ on Spain,

I remove old one, and install this new. Fit ok, but maybe add additional flat washer on the upper side will be a great idea.
I will replace the another FPR (another is ok, but surely it will break soon because car was parked 1 year at least).
Now time to go to the garage shop for repair the AT leak (finally it was AT fluid). But I dont have a safe place to do it.
This topic is "closed", but I hope everybody had some problems with 750iA wont start, can get here some info.
Thanks you shogun, without your help, I dont can repair this incredible machine .
The S.I.D.A.T fuel pressure regulator 89.010 should fit, looks same and is for 3 bar.
The usual leaking points on the transmission: front input shaft seal, rear seal, side seal for the shifter. For the input shaft seal the transmission has to come out, then do all 3 seals at the same time. But first check the trans oil pan gasket and the area where the dipstick for trans level check is located.
