Long story, but she started with 6 gal fresh gas and starter fluid spray, ran rough then died. Ran codes, replaced HPFP and Tank fuel pump (didn't look gummed up at all just woudn't fire up with confirmed power going to it) with new OEM parts. Now it wont start at all, codes are P0102 (MAF voltage low), P0113 (IAT sensor circuit high voltage) , P2623 (HPFP spill valve malfunction), P0201 (No1 injector circuit malfunction). Mechanic thinks its a bad injector, please help $$$ *** deep into throwing parts at this thing need to get it right. Thanks in advance. 84k mile car, worth saving.

 

I wouldn't put any more parts into this car until you narrow down the problem(s).

Did the car have any issues before it sat for two years?

You have individual codes for very different systems. Do you have a scanner that can read/clear the codes?

 

Did your Accord run until you replaced the fuel pumps?

 

Mechanic thinks its a bad injector..... I totally disagree with your mechanic
One bad injector is not going to make the car not start , it would cause a misfire on that particular cylinder
did you chk if getting spark and fuel?? power at fuel pump and out of it ?
Like PA advised don't replace any more parts till you properly diagnose the issue
