The day before yesterday I was out with my son when out of nowhere the vehicle began sputtering as if out of fuel and stalled. The vehicle would turn over but would not hold power. We had driven about 45miles. The vehicle had to be towed home and once there started right up and drove straight into our spot. The following morning I went out to check it out and it started right up and seem to be ok. Thinking it was something that had worked itself out I ran the errands for the day. After about 45 minutes the same thing....sputter....stall...again the vehicle would crank and occasionally start but would die out as soon as I put it into gear. Again the vehicle was towed home and again started right up and drove off the truck. Only now the check engine light has come on. The vehicle is parked until I can find a solution or the problem to see if it can even be afforded to be fixed. About 4 months back I had a oxygen sensor replaced because the check engine light was on... could it have been a faulty sensor/ Or a different sensor/ Or a fuel line/pump problem..../

The first thing to do is have the codes read to see if they give you any inside into the issue.
Here is how you find the problem.
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.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.
