I think that the problem is solved. Found 2 broken wires in the MAF harness, fixed it and everything was the same. But now, when I changed the MAF for another , made a huge difference. So, broken wires and defect MAF was the problem !!

Do you mean the Pump ECU?

Fuel filter changed !! Problem continues

What is confusing me, is the fact that if it was the pump ecu, shouldn't be the engine light always on ? And not intermitent ?

No DTC for that shows up

Also, sometimes when is ideling will die on me, but starting again without any problems and without triggering the engine light.

Does a fuel filter make the engine light go on ??? With the error "Bad comunication with ECU" ??

Finally I got the picture posting right :clap:clap:clap

Is it supposed to be like this? Thanks

Cleared the codes on the ECU, and went for a run. Before the run, checked for errors and gave the " no errors found " code. After a while engine light went on, checked for errors and the 703 appeared again. Could the fault be on pump ECU? :(:(

Will do that , thank you solarman216

Was reading the codes in the wrong way, is 102, 403,and 703. :banghead:banghead:

Ok, so I got the following codes from ecu. 12 - MAF ( broken wire ) fixed 43- crankshaft sensor 73- ???? Doesn't come in the manual Help !!

Hi, first thing that I noticed was a broken wire in the MAF socket, and another one is striping. Did a quick fix on it. Now the seems to go a little smoother, the hickups still come up, but in a lower rev range and usually after a roundabout. Which makes my guess that is a fuel related problem...

The pump was sent to repair by the previous owner, don't know if the warranty is something that I can ask for, and they are 300 miles away !!!

My OBD reader doesn't connect to the ECU. So i'm almost certain that there is no Pin 7.

Yes, I agree and looks like is the basic place to start. The source !! Will start with the filter. Is there any test that I can do to see if the route from the tank to the filter is cleared enough? So that I don't have to replace the fuel lines if there is no need to. thank you
