No start issue after valve job 2005 silverado 4.3

[Peachesandherb]

I picked up a 2005 silverado v6 that supposedly needed a valve job. I took the heads off and had them redone. I got the engine reassembled and hooked back up last night but it won't start. Checked my spark on cyl 1 and it's good, fuel pressure is at 60psi. I checked some fuses under the dash and in the engine compartment, all looked good. Pretty sure my distributor is on right, set the notches and white mark evenly then seated it in the block and it turned to the 6 mark cyl 1s valves were both all the way down with the timing notch set.

 

Any suggestions as to what I should check next? When I pulled my starter to replace it, it was full of water and the inside of the truck was pretty moldy smelling which makes me think it could have been a flood truck?

Shoot a little starting ether or brake cleaner into the intake, then crank her over. If it fires for a second, you've got a fuel problem. If it still does nothing, you've got either weak spark or a compression issue.

 

Your sure the valve timing is correct? Crank position sensor good & plugged in?

My first thought was a couple of inches of water in the tank. Water and gasoline do not mix, and water will settle to bottom of tank, right where the fuel pick up is located. Does not take much water to impact the fuel quality getting to engine.

 

About the easiest way to get the water out is to pull the fuel line off where it connects to engine and finding a way to re-route it into a pail or gas can. Run the fuel pump to get the water out. The water will be the first stuff to come out. Run the pump until you know for sure it is gas coming out. You are likely best to completely drain the tank, and use fresh gas though. This is where the old days were better, back then you just needed to drop a fuel line into a gas can, connect it to fuel pump, and you were getting new gas.

If this truck was a flood vehicle, and was written off my insurance company, it should show up in Carfax as being a flood vehicle. You can also do some quick and easy detective work by going through the list of previous owners on the title. See who owned it, and when they owned it, and where they owned it. Do a quick google search for floods in those areas during the time the truck was there. This is not conclusive by any means, but is a good start.

 

Flood vehicles are written off virtually every time, regardless of vehicle. In the Toronto area last summer there was a rather well publicized case of a Ferrari being abandoned in a flooded area. It was written off, all $200k of it. Pure water is a poor conductor. The stuff in the water is what is conductive. When water dries, it leaves the impurities behind, those are conductive in most cases. That is generally what creates the issues for years to come in a flood damaged vehicle.

If and when you get all the water out of the tank I'd be ready to change the fuel filter as well. If water is coming through the lines, who knows what else is coming with it...

I tried starter fluid multiple times but that hasent done anything. No signs of a combustion. Also I read somewhere that if you have spark from any of the cylinders, then the cps is good.

 

Since starting fluid didn't work, that would put the possibility of bad fuel back on hold right?
