It started with no hesitation and I was driving my 97 S-10 to work and on the interstate when the truck just died. I had to coast over to the side of the road. I have a half tank of gas and have not had any problems with this turck until now. What would make a vehicle just die while your driving it.

Please help, I'm confused
Do you
have the same problem?

Check for fuel pump operation. Also check for spark. Either one could cause the failure you have.

Do you hear the fuel pump turn on and run a couple seconds when you just turn on the key? If not suspect a failed pump.

I just had the same problem I have spark( good blue spark at all four plug wires) and fuel but still wont start the fuel presrure at the "rail"(rite b4 the injectors) is a lil low like 22- 29 instead of the 47 I think its susposed 2b. But even if I pour some gas straight in the throttle body it still doesnt start at all coul a regulator o sensor be to blame oh I have a code to but its come on prior to this b4 po452 evap control system presure low but it comes on when ever im a lil low on gas it seems tho so any help would be greatly apprieciated ty jacob.

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.

Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.

2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.

3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

4) If all of these things check good, then you would need to do a complete compression test.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

Ok I have spark good blue spark at all four plugs injector pulse idk yet I will have to get this noid lite thing or can I just check them sum way with a dvm? Fuel pressure low only 22-27 psi I think its sposed 2 be 47psi? And it doesnt hold there at all drops instantly! Do you think fuel pump? Or can the regulator afect that as well oh this is a 2000 chevy s-10 2.2 auto normal fuel (not the flex fuel with the speacial fuel filter) can I make this noid light? And there is some kind of testing looking lite(looks like a very small bulb or maybe a resistor or capicitor? At the end of a 8 inch wire beets me 2 what the hell it is tho damn I need a haynes for this truck just got this thing a, omth ago tho) over by my main electrical fuse wiring harness area

If you only have 27PSI of fuel pressure, that is preventing it from running. The spec is 41 to 47PSI. Don't try anything on the injector test but a noid light or you could to damage to the computer. You can buy one for under $10.

So would the low presure and imdiete presure drop be caused by a faulty pump I know theres somekind of one way ball thing in most eletric pumps that still doesnt explain why its pumping at only 27 wtf how does sumthing half break? Well maybe il open it up and it'll majically just be clogged with crap or sumthen. Any one know where to get a fuel pump for less than 240? Damn why cant they sell just the elec pump and not the whole damn unit and I really dont want a junkyard one dont want to make thia an every few month thing ya know :(
