When at a stop the truck engine runs rough.also noticed voltage gauge fluctuates like 1 volt

This make/model has a chronic problem with EGR clogging. If you have a dashboard indicator showing "check engine" most likely it is a trouble code indicating and EGR (exhaust gas recirculator) valve problem. Symptoms are rough idle, and surging and stalls.
What happens is sediments from the exaust manifold get sucked up into the valve when it opens, then stick in the valve and keep it from closing. When the valve is open when it should be closed, the engine runs very rough.
I removed my egr and then dislodged the sediment (pea-sized debris) and then re-installed the valve. Three days later, the same "check engine" and same rough idle. I must have did this at least three or four more times.
What I found that gave me a permanent solution was an aftermarket filter gasket that keeps debris from clogging. I don't remember the name of the product, but a search for "EGR filter gasket" may lead you to the product.
Install the gasket between the EGR and the exhaust manifold and you should be good to go. Note: on 1995 and newer models, disconnecting the EGR from the wiring harness (common on R&R) may require the computer to be reprogramed.

if you replaced the tank and all i assume you didnt change the fuel pump. if you dint then all thats wrong is that the float on the fuel pump is gas logged and will move more than if you had put in a new pump thus the fluctuation in the guage.

yes it is called the "rollover switch" usually located in the "trunk" area by the fuelpump follow the wires then reset the switch

If/How long will it crank over before it stops? Are you saying it will crank over, but very slow? Has it been sitting quite a while. Got good spark, and fuel?

Very common problem with chevey over time the gauge goes bad, but first take it to auto-zone and have the voltage checked if it's 14.5 volts if it is the altanator is most likely ok. You can buy a new gage at any dealer $15.00 and remove the four front bezle ring or beauty ring 4 screws two on top two on bottom. Then pull the plastic cover and pull the volt gage out and push in the new one in it's plase and your done.
