Check the fuel pressure at the engine and plugs for spark (ignition module).

Hello Johnholley
I am wondering do you hear the fuel pump when you just turn the key into the on run position not crank just in run and listen and see if you hear the fuel pump run for a second, If you don't hear it you will want to check for power at the fuel tank, and have some one cycle the key while your under the truck with a test light. Hopefully you have power and you hear the fuel pump run. Now if you do hear the fuel pump running then the next thing you will want to check is for spark, It could be the ignition module or pickup coil. check out those thing and I am sure you will be able to figure out whats going on. If you don't get back to me and we can try a few other methods. I sure hope that helps you out johnholley. and thanks for using Fix Ya Bear001

Fuel pump is most likely the cause. Probably just barely making the required pressure to start. Needs to maintain 60-66 psi while cranking to start.

Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.

SOURCE: 97 chevy 4.3 liter no spark no fuel pump running.

4.3 and 2.8 motors have a ceramic module in the distributor. if you have alot of miles on the truck, and there is no spark, that module is usually the culprit. easy to replace with a nut driver and some dielectric grease. mod is located in the distributor when you take the cap off look straight dowm and its right there.
also check eec relay and fuse. that will also cause the prob.

03 Chev 1500HD Ran out of gas. now wont start


I had this same problem and first i took it to the chevy dealer and they charged me 2500 bucks to change a bunch of stuff that didn't fix the problem this included the starter and O2 sensors and a computer board. To say the least i feel like they took me to the cleaners and didn't fix it anyways. The same problem happened again and i took it to my local mechanic and he said all it was, was a 20 amp fuse under the hood and charged me 10 buck to fix it. I'm not sure which fuse it was. But i would start there.

sounds like the crank sensor if you have fuel do you have a fuel gauge it should be about 70-110 psi on the fuel rail
