OK, go this morning go to start the teggy and just crank no fuel pressure! I am a tech at Infiniti dealer so I am like ok quick fix. the guage is reading 0 on fuel filter. I am like fuel pump, new fuel pump install and no start. I wait two hours and it starts when I was showing another tech the symptom's. We laugh I put old pump in and it starts. I get home and its starts acting again. No codes. Did ECU reset. I start checking over sensors like that would tell the ecu to not start like engine temp sensor. I clean the ground at the thermostat housing.


Part 2: I do have a LSVTEC engine in the car. It has a P28 ECU. The place that reflashed the ECU did the normal frankenstein program. I have had this setup for about 4 yrs. The motor has proved to be strong for their reputation. I also have a AEM fpr and have heard they are inconsistent. If that was bad would still have pressure on guage. I know it's the fuel pump please help. I am alittle curious as to what it is. I am very perplexed cause I fix sh*t like this on a day to day buisness. honda and Infinit are way different!ousing. I push various connectors in the engine bay to ensure good connection. Someone said it might be PGMFI relay gone bad!
