Hey Guys, I recently had my truck engine swapped and re-sealed by Ryan Baxom out of Warrenton, Va. He did a great job and I was pleased with the work. I picked up the truck in January and drove it with a buddy down to Nashville (my new home). About 2 hours outside of Nashville, right after filling up the tank with gas, it randomly stopped died on me and I had to pull over. The engine would turn but it was not receiving any fuel.

I had the truck towed back to Nashville and I started working with a retired Toyota mechanic down here, Charles Trueblood. Since my truck stopped working shortly after filling up on gas, he was convinced that I received bad gas and that it had a bunch of water in it. I will spare you the amount of times I picked up my truck only to drive it less than 2 miles and for it to break down again. Here is what we have done:

We:

1.) drained the tank and filled with good gas.
2.) Changed the spark plugs (mechanic said water in the fuel caused the plugs to go bad),
3.) Got a new pump and filter
4.) Dropped the gas tank and cleaned all rust out of the gas tank (common problem for rust to occur in these trucks)
5.) Replaced all the fuel lines

I drove the truck to get coffee this morning after my mechanic had been working on it since 9 PM last night. Drove like a DREAM on the way there. Got coffee and started heading home and it started choking and sputtering. It would kick in and drive fine for 200 yards and then back to sputtering. Barely made it home.

I called Charles and he said he thinks the fuel pump and filter are bad due to junk being in there from the rust in my tank. Something tells me I will still have the same problem if we do change out the pump and filter.

Anyone have any ideas of what could be wrong???

It is driving me nuts as this car should be driving close to perfect.
 
You said the fuel pump was already replaced (hopefully with a Toyota pump).
The fuel filter will protect the pump & carb from debris.

When the engine bonks out, take a look at the sight glass in the carb. When you shake the truck you should see some gas sloshing in there. If not, then there's still a fuel delivery problem.
 
^^^ That, and also was the carb blown out or anything??? There could be stuff floating around in the fuel bowl that is clogging the jets intermittently if you still see fuel in there.

Do you have any idea when the last time the carb was touched? Could need a rebuild due to crap being in all the little fuel pathways and what not.
 
I just tried running the truck again after letting it sit for an hour or so. Driving perfect again. Seriously stumps me.

I rebuilt the carb and replaced the fuel filter while it was here. I'm wondering if the fuel cut solenoid is randomly acting up since it will run perfect for a bit, conk out, and then run well again.

Good call, could be. But wouldn't you see that more at idle vs. while it was driving. My understanding was that the ICS handled fuel delivery on decal and idle only, otherwise the rest of the fuel circuit would take over (hence why the system runs without the ICS if the choke is pulled).
 
Usually a fuel delivery problem results in sputtering, hesitation, lack of acceleration, bucking, difficult idle but not usually the engine just dying, then sudden running perfectly an hour later.

Sudden go/no go issues can be ignition problems (not to say that definitely is the issue) and the primary suspect for that symptom is the igniter or maybe the coil. So don't rule out that possibility.

The fact that the tank got filled, then the problem started doesn't mean the two events are related.

I forgot to mention we replaced the coil..
 
Bring a timing light & clamp the pickup on any wire. If the igniter isn't working the timing light won't flash (no voltage pulse going to spark plug).

If you don't have a timing light it will be hard to check by yourself because the engine has to be cranked to see a spark jump from a pulled spark plug.

You could get a spark tester.
 
Or you can take a jumper wire and clamp it to ground ie the neg post on the battery then to the spark plug unscrewed from any cylinder hole but still on the plug wire. Hold the plug with rubber coated pliers or just lay it on something. Have someone crank the motor and look for spark.

Also your issues remind me a time when my egr got clogged and the engine would cut off on me and had a hard time restarting. If you have smog stuff might try beating on the egr with a hammer a couple of times while you crank. If after beating on it you see some carbon debris in the bottom of the air cleaner you'll know the egr was clogged.

Before replacing the fuel pump. Can you disconnect the fuel line from the carb, crank the motor and catch the fuel in a clear jar? See if its pumping fuel, see if its clean.

double check the connection to the green plug (fuel solenoid) on the carb. I ended up cutting my green plug off and just putting new blade terminal type connector.
