Land Cruiser, Won't Start

[lcmariani]

I was driving down the highway and it started to beep. I pulled off the side of the road and shut it off. I am not sure if it shut off before this or if I shut it off. It turns over, but wont fire now.

I tried another key
I check to see if the security light goes out when you put the key in it. (immobilizer) The light goes out.
I replaced the EFI 20A fuse
I cleaned out the Mass airflow sensor with electronics cleaner.
I cleaned out the fuse box and checked the fuses in the big fuse box under the hood.
I disconnected the fuel filter and tried to start it. When my gf turned it over the fuel sprayed out pretty strong.

The day before it died I was driving it though torrential rain. Most people were pulled over, but I could see so I didn't pull over. I think this has something to do with it.

Can anyone help?

Check for dampness around the firewall on the floorboard.

I'm feeling like a big phatty windshield leak....and a phatty expensive ECU.....mated. Did you check the ECU B fuse...drivers' side....left underneath dash near hood release?

I am starting to think I have that problem as well. I noticed from the day I bought the thing that the windshield replacement was shoddy. I will check the fuse now.

I checked all of the fuses under the dash. When I first looked at it I was shocked because the ignition or igniter fuse was crooked in the slot. I pulled it out and placed it in there correctly. I checked the ECU B fuse and it was still good. I removed it and visually inspected it.

I did not notice any dampness. I think that if the windshield was leaking that there would be some rust under the dash because there is a lot of bare metal. I did not notice any rust.

Let's hope no leak. I'm assuming you've already pulled the battery cable and let it sit. Also, just for fun, you could pull the Body ECU from behind the radio and inspect it. Easy to get to. 8 minute job. Someone else would know more about this and could chime in, but I know a CPS could cause this too if it went bad. Had a friends jeep out on a trail in badlands Indiana one year. Wouldn't start the next morning after a water crossing. Turned out to be his CPS.

Before you disconnect the battery did you check for codes? Or maybe changing the efi fuse reset it anyway...

Thanks muddy bean. I will pull the body ecu Sunday. I bought a voltmeter and I was going to check the fuse boxes. Initially it threw a p1305 ignitor circuit/bad no 2 coil pack. I had a spare so I replaced the coil pack even though I knew it wasn't the problem.

Be very careful poking around the ECU with a voltmeter. You could make a connection through ground that isn't supposed to be and cook things.

And that would ruin your day to the tune of around $900. I just wanted you to see if it looked like any water intrusion occurred.
