i have an 01 xterrxa which my friend submerged for only like 5 min the front passangers side water was level with the front seat(it was at a angle back driverside was up the highest and front passanger side was lowest ). i had the old trusty suburban there and pulled it out but had to yank pretty damn hard. it was running the whole time until we got it out and my friend in a panic i think shuting it off now will not start just turn over. HHHHEEEELLLLPPPPP.

If it cranks but will not start with the water level you are talking about could be a number of things. Distributor full of water or submerged/soaked ECU would be where I would start. Also need to check for water in the engine oil.

submerged

no water in oil and distributer. i pulled the computer and it looked good inside and out, but i am not to sure. it was under water though the water level was if looking head on the passanger side water was up to middle of head light drivers side was bottom of headlight at an angle like that . is there any way to check the computer???? thanks steve

You can take the computer apart, unscrewing the assembly screws and pulling the case off.

Then look for moisture, drying it off with a hairdryer on cold (don't put too much heat on the motherboard or you'll be doing the screwing up!).

But, a little diagnosis here might help out.

Does it have spark? Does it have fuel?

Check for spark by pulling a spark plug wire off and turning it over. If you get shocked or see a spark coming out, then you have spark.

Take off the fuel line from either side at the intake. If you see fuel coming out when you first turn the key on, then obviously you're getting fuel. If not, then look at the fuel sending unit on top of the gas tank, accessible via the access plate under the right rear seat. May want to check ALL of your fuses first, just to be sure you didn't pop one while being under water. The connectors are moisture proof to a degree, not submarine proof though.

i have fuel had already checked like suggested. also took apart computer no moisture or crosion . no spark is where i am at. when i took out computer and turned on ignition all light but check engin and once i put it back in after inspection the check engin light was on so i think the box is ok. now back to spark is the computer what tells distributer to spark i know the coil is part of distributor right?? thanks steve

Yes, the computer tells the distributor to fire when needed.

So all of your fuses are good? Even under the hood?

I'll see if there's a pinout for the distributor and see if I can point to where to look for power. But it sounds like if you're getting fuel, your computer is still operating (the computer controls the relay for the fuel pump too).

 

[Cyclemut]

Make sure you have power at the Black/Purple wire at the distributor. Pull the connector off and, with the key on, check for 12v there. If not, then look hard at fuse 27 (10amp, far right, 3rd one down inside the cabin) to see if it's blown.

 

[djstevod]

still no luck replaced distributor and nothing fuse looks good is it ECU???????

 

[piratex]

What about your altenator?

 

[djstevod]

I don't understand what that would have to do with it not firing ? It turns over just no spark . Has any one had this problem??????

 

[piratex]

My bad I didn't realize that it is indeed turning over.

 

[djstevod]

so i am at a loss ecu tells the distributor to send spark right? OH i yanked it pretty hard to get it out of the water could i have tripped a sensor. or is there any reset switch. can you have ur ecu checked??? thanks guys

 

[Cyclemut]

Did you check for voltage at that wire or just check if the fuse not blown? Rather than spending big bucks, lets diagnose the problem.

Check for power at the wire I listed previously.
