Hello Forum,
So my 2007 GX470 w/ 90k miles was off the road for 8 months...
I had to replace a broken (rusted...) brake line that ran above the gas tank.
Brake line has been replaced, brakes bled, gas tank reinstalled, and now it's time to restart the SUV.
Note: I consider this a very well maintained GX470. I'm a car guy, also own a LX470, several vintage Triumphs, etc.
The gas tank was drained when it was removed 8 months ago, with the exception of maybe 1/2 gallon of gas.
The battery (now a year old) was pulled and put on a charger at the same time.
SUV was in a clean dry garage during the entire 8 months.
It ran well before it was taken off the road.
I've added about 5 gallons of premium gas to the tank (gauge shows 1/8 of a tank).
Battery is very good.
When key is put in ignition (master), it immediately turns off the immobilizer light.
I've tried all 3 keys (2 masters and 1 valet), and they all do the same thing.
It will crank (starter engages just fine), but it won't start / run.
After spending some time with a multimeter, I'm pretty confident that the Fuel Pump is not getting power.
I've checked / switched all of the fuses and relays.
When I turn the key to the On position, the fuel pump should run for 2 or 3 seconds.
I don't hear / feel the pump run during this time.
Anyone heard of a condition where the immobilizer light is off, but it appears the immobilizer is still cutting off the fuel?
I'll test the fuel pump tomorrow, but I'm 95% sure it's not the pump.
Are there any sensors that would cutoff the fuel if there's an issue?
The following items have not been reinstalled, but I don't believe they should be a problem:
- Gas Tank Skid Plate
- Engine Skid Plate
- Transmission / Transfer Case Skid Plate
- Front Engine / Radiator Cover (needed to remove to put in the Battery)
- Fuse Box Cover in the Engine Compartment
- Carpet and Gas Tank Access Plate in the 2nd Row
Any help is greatly appreciated.
Thank you.
Tom
