Ok so this exact setup has been running fine for almost 3 years now.
s13 chassis
s13 - J4 ecu blacktop sr
All supporting mods
professionally prepared harness
walbro, etc
A few days ago the car was running just fine, but towards the end of a short drive, the engine started running like crap; almost as if it were running on 3 cylinders. Later that day the car wouldnt start, and had to get towed home.
Fuel pump is not getting powered. When I hotwire the fuel pump directly to the battery, it starts, but runs like crap again. Pulling the injector harness for the no. 1 cylinder makes no change in the way the engine runs. (bad)
Does this sound like ecu issues?
BTW this was tried with and without the maf plugged in.
all relay's and fuses were checked with known working components. Opened up ecu, no obvious burn marks or anthing. First time its ever been touched.
