Engine won't start?

Check yoru fuel pressure should be 41-47 psi min

Check the voltage (using a voltmeter) to the fuel injectors when you are spinning the engine over trying to start it. It should alternate between approximately battery voltage and 0 volts.

Also, check the computer codes and post them here. This way we'll have a good starting point in diagnosing the problem (otherwise we'll have to check everything!)

What size engine does you car have.

If you can spray fuel and it runs it sounds like a fuel problem. Get your igniniton mocule checked auto parts store can do this, you may not be getting ignition for the injector s to work. Also when you test fuel pressure it should hold pressure for 5 minutes after the key is off if not then check regulator. Also check cranks sensor connector as it may be bad. This cold be a pcm or prom problem as well.

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.

Hi:
If you have spark, fuel, and compression it should run, unless the timing is off. Have you checked the cam sensor? How much compression does the engine have? Does it try to start or backfire?

Let me know.

Scan for codes and check fuel pressure. Shold be 41-47 psi. Check map sensor and hose leading to it if yo have one. It also could be crank sensor as they had problems that year with those.

Try changing the plugs. Make sure you properly gap them.

BTW: I dought letting your sister drive the car has anything to do with the cars problem. Keep in touch

Check fuel pump and fuel pressure
check tps and mass air flow sensor

Sorry for the late reply.

How long since a tune-up? Check for applicable trouble codes, your obd1, you should be able to check mil codes? Use a gage and check proper fuel pressure. Also, check that the pressure will hold for a bit with everything off.
Smell of the crankcase oil dipstick, see if it smells like gas?

I realize this is an old post. In the future, hope you don't have any vehicle issues, but, if you do, keep the site in mind. They are always working to improve the site and it's free to ask a question. They have more moderators now, to answer questions, than they did a few years ago.
Have a good day.
