What could cause this to happen...

[Dafey]

Driving along she just dies , no stumbling or any thing. Then it would start but as soon as I put it in gear...dies.
Ok then I put 3 gals in and drove 3 blocks to the gas station. It only held 8 gals,total of 11 so far.Drove home 1 mile no problem.
The RPO tag says I have an 31 gal tank, so I wasn't out of gas..... :shrug:

P.S. I was having a bad pinging problem , now with all the better octane and brand of gas its 90% gone. I still need to find someone with a timeing light and set it.

Maybe the fuel pump going bad? Do mechanicals act up this way? I know they can leak gas into the oil.I`ll check on that tomorrow....

Mine didn't act up on me at all. 30 miles from Moab, 80 miles from Grand Junction, nothing in between, midnight-thirty, -3 degrees, truck dies right after I got on the freeway. That night sucked. Filled up in Moab, so I had gas, wasn't sure what happened until I popped the hood and shined a light down the carb. It was a mechanical pump. That's the only one I've had die on me, but I don't think there's much chance of them going in and out like that. If the diaphragm goes, she goes. I recommend an electric pump anyway. One, it's easier to test, two, if you run out of fuel, you won't kill your battery getting fuel back to the carb (assuming you didn't know what happened and put a drain on the battery trying to get her started w/o fuel), 3, you won't be stuck on the side of the road trying to change a fuel pump in the dark with frozen hands, trying to keep the rod up to get the new pump in... Bad memories.

I think you may be having an electrical problem though. Check the wires running to the starter. Make sure none have touched the exhaust and melted. This can cause an intermittent problem like you described. Check connections on your coil too.

coil could be going out.

i thought you couldn't have too many "gals", but all those chicks are maxing out your hauling capacity, even if they only weight 100lbs apiece.

ok, lame jokes aside, you can get a fuel pressure gauge and fitting for pretty cheap. you can get a new fuel pump even cheaper, though. how old are your fuel lines? it's easy to find a leak in one one with an in-tank electric pump because the line is pressurized and the fuel can spray out. it's harder with a mech because it sucks the fuel, so a pinhole results in air being sucked in, not fuel being forced out. i'd check the fuel filter(s) also. i pulled the filter out of my stock q-jet and replaced it with a clear inline filter. it's less restrictive and i can see what's in it. i also put on before the pump, but that's not really necessary.

Thankfully It happend to me in the middle of town , half a block from a pay-phone @ 4pm, Because I had my 7 yr old daughter with me.

Hey dont you carry a spare tire and such? Well I carry a few spare "gals" also...

I have a new filter in the line from the pump to the carb.
I`ll chech the wires on the starter and coil , and test the coil.
God knows how old the pump,coil and a hundred things on there are.So it very well could be the coil or pump ...hummm
