Ok looking for ideas, I have a Spain built 09 navara d40 diesel 2.5. Something is tripping my ecu which is playing with the fuel pump then causing it to smoke like a bugger, I do a ecu reset and it stops smoking. I have replaced the maf sensor, cleaned and proven the egr, replaced the fuel pump, cleaned out the intercooler. Had two separate people do fault scans and shows nothing. I did take out the exhaust system and put 3" straight pipe system in it because it kept on going into limp mode really bad. I'm running out of ideas to what's going on. Any info would be appreciated.
