Engine not starting

Got spark and fuel now next step is to check the valve and ignition timing

Do you mean it cranks over and will not start or just won't crank at all/nothing/nada?

Cranks and w/n start

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it

No crank at all/nothing/nada:

Could be the starter, starter relay, park and neutral switch and ignition switch assuming the battery and connections are good.

Scan for codes and check fuel prpessure first check fuses underhood

Injectors don't produce voltage so all you can check is the signals to it which you need a noid light for.

Here's what you have to do.

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.

Listen to the injectors if its clicking or use a noid lite and also verify the valve and ignition timing is correct-

What I would start with is checking fuel pump pressure and pressure drop off. My first thought is that the pressure is dropping and taking time to get to the engine. Under the "Do it Yourself" site on our home page, you will find directions to check fuel pump pressure, the pressure regulator, and drop off. Do that and let me know what you find. Also, pay special attention to drop off. That is when you turn the key off. The system should maintain pressure for some time. If it drops off quickly, there is a leak somewhere causing the hard start. You will need a fuel pressure gauge. Many parts stores will one to you.

Let me know what you find or if you have other questions.

You need to check for spark at the plugs, injection pulse and fuel pressure, can you do this?

If you need help just re post

Start by having the battery and alternator checked. The battery could be week. It may have voltage to power some lights but can't suply curent to the starter. Also have all fuses and fuse links checked thay looke like large fuses.
