Many know that I have been fighting fuel injection issue's for many years...
I first tried MAF and could never get it running right. .so went with TBI and I'm still having problems.
Its running insanely rich... I have replaced the coolant temp sensor, MAP sensor, O2 sensor, and they test good (not sure of the o2 sensor tho)
Today I messed with running codes with some help from friends on Facebook... and I'm not getting any trouble codes...so I unpluged the TPS and map and coolant sensor, the only code I got was 34 (map sensor) with the same results again and again..
So I hooked everything back up and tried a different computer and was still running rich. .so I unpluged the coolant temp sensor wile it was running and it turned my check engine light on, so I turned it off and ran codes again and got a code 15 (coolant temp sensor) Plugged it back in and again, no codes.
Fuel pressure is at 12psi (sweet spot is 14-18)
I'm not 100% I have the harness wired up correctly. .but I can't seem to find anything wrong, but could be blind to the problem. .
Now, to put in prospective how rich it runs...I burned up 2 gallons in a total run time of around 30 mins....
I'm at a total loss...and so sick of messing with it...and ideas?
