p0335



Disconnect connector B-117 and measure at the harness side.
Turn the ignition switch to the "ON" position.





Measure the voltage between terminal No.2 and ground.
Voltage should be between 4.8 and 5.2 volts .

there is also testing using a scope, but you can test voltage with the OEM info above.

Glad its fixed. I am just wondering how you missed this when you checked if the fuel lines were intact at the pumps.

well i checked all the lines on top of the hanger to the engine bay and all seemed fine. i even undid the line under the tank that goes to the steel line to see if i was getting flow. it filled up a water bottle within seconds so i thought all was good with the pumps.

but bad news is it just happened again a few hours ago. i was stranded in a parking lot in the middle of the night for around 45 min.

eventually a buddy showed up with tools and had it back up and running within 30 min. i made sure to tighten down the clamps real tight the first time but for some reason that second pump managed to slide out again

i replaced the lines with something different that i know for a fact are e85 compatible. hopefully it wont happen again

i might just need better clamps or a better way to secure the pumps to the hoses
