Damn Truck wants me killed

My truck runs beautifully, the other day, on the way to town, I passed a few cars and nearly hit 60 mph on the highway. My amp meter was fine, my oil pressure was fine, my temperature was a comfortable 170, and the truck idled well in intersections.

I parked the vehicle, did some work for two hours at my job. Then went to drive home. I had trouble starting the car, it would start, and then die after a few seconds, I would pump the accelerator, but it would not rev. Eventually I started the car by choking it down all the way, and running the starter with the gas pedal all the way down. I pulled out onto the road, and the car started to cut in and out. It took me nearly an hour to make the 8 mile trip home. I had to rev in first, shift to second, and then quickly shift out of second when the car started to loose power. I would goose the accelerator until it revved again, and put it back in second. I could average about 15 mph on the flats, and on hills I had to stop and start, limping my way up in first gear.

I'm lost?! Where should I look first. The problem has happened every time I've driven the car, but only after I've driven it into town, let it sit for a while, and then tried to drive back.

ey oop

first off - IT AINT A FOOKIN TRUCK! is says Land Rover on the front, not Peterbuilt.

second off - what engine / carb combination have you got?

Am gonna say carb icing, just because of where you are

Its a truck. A Peterbuilt is a Semi.

2.25 petrol, weber carb 34ich with an oil bath filter, I just modified the hose end to fit it on the weber.

As for carb icing... Its been about 60 or 70 Fahrenheit here lately, so i'm not thinking thats the problem.

Actually a peterbuilt is a tractor unit, put a trailer on it THEN its a truck, then put a towing trailer behind that, THEN its a semi.

So, whats wrong with your peterbuilt?

A Semi is a house.

... Does anyone have any ideas about whats wrong with my truck/car/land rover?

Coil?

yu are trying to drive 3 vehicles at once?

Sounds like gas/petrol starvation to me, bear with me please, Smilemon.

Depending on which type of stand/suction pipe you have in the fuel/gas tank..some are included with the fuel gauge sender unit and some are just a separate pipe...the fuel is sucked up the fuel stand pipe inside the fuel tank, this vertical supply pipe can over time crack and allow air to be sucked into the fuel system causing fuel starvation.

Also theres normally a fine filter on the bottom of the stand pipe, I've always taken the filter off and relied on the external filters, I'd be inclined to remove the gas tank and make sure its totally clean inside.

I had a series 1 that would pull up hill and cut out down hill, the brazed joint between the suction pipe and the elbow at the top of suction pipe had failed allowing the fuel moving around in the tank to open and close the cracked joint, it was fun to find.


As stated an ignition coil overheating could be a possible cause but being parked up for 2 hours should allow it to cool, but it does sound like fuel starvation to me.

or a semi lobon

An engineer friend of mine said that it might be getting heat soaked. The Radiator fan is keeping the gas line cool when I drive, but as soon as I turn the "vehicle" off the fuel in the line turns to vapor, causing the car to become fuel starved, as the pump can't pump vapor.

Anyone heard of this before?

Yeah, but that was in Saudi Arabia in 120 degree heat which causes batterie fluid and petrol losses occasionally through evaporation.

I've had issues like you describe twice in cars (not in my landy tho). First time it was the coil overheating, second time the carb was flooding.

How does the engine sound? lumpy? if so do a pressure test you may have a inter-cylinder gasket blow and you are runing on 2 cylinders.

The engine sounds great, It doesn't blow any smoke, idles well, and can pull the truck up hills at a comfortable 50 mph.

It only starts acting up after I shut it off, and then try to turn it on again...

I'd have a good strip-down and check of the carburettor, especially the float bowl and jets, and also the throttle cable and how it opens the carb. Might be the choke butterfly sticking, or the needle etc ......
