First let's see what's missing, fuel, spark or both. Do this remove a plug wire or coil on plug the insert a screwdriver into the boot and then hold the metal part of the screwdriver 1/2in. from a metal part of the engine block then have someone crank the engine while you watch for spark. Check fuel, do this remove the cap from the fuel rail test port and depress the schraeder valve while someone turns the switch on, fuel should spray out. NOTE to avoid fire do these tests in this order. I wonder about your fuel pump. I hope this helps. Take care.
Is the engine turning over and not firing? Check the schrader valve on the fuel rail for pressure. Remove the air filter and spray starting fluid into the intake tube. Have a second person turn the engine over till it fires. If you have adequate spark to the cylinder and starting fluid reaching the cylinder, it will fire. Don’t over spray the cylinder.
I thought I answered this already. Check for spark and fuel. Do this, remove a spark plug wire insert a screwdriver into the boot and then hold the metal part of the screwdriver 1/2 in. from a metal part of the engine block then have someone crank the engine while you look for spark, check fuel, remove the plastic cap from the fuel rail test port the depress the schraeder valve and have someone turn the switch on fuel should spray NOTE! Do this in this order to prevent fire. Do you have a spark tester? If not find an old spark plug and open the gap really wide like 1/4 in then connect it to a plug wire or coil pac, unplug the injector for that cylinder to avoid filling the cylinder with fuel then start the engine, does the spark quit as the engine dies. Clear misfire code before going on. I hope this helps, take care.
I take that it does crank over? If this is the case you need to determine where the problem is, are you getting fire to the spark plugs? or is fuel not getting to the engine. If you know you have fuel pressure to the fuel rail, and the pump is running when you are trying to crank the engine, make sure that the injectors are spraying fuel into the engine. If you have verified that you do have fuel and it is getting into the engine, make sure you have spark to the plugs. It could be the pickup in the bottom of the distributor, this is what fires the coil and meters the injectors.
Got fuel? Sounds crazy but you'd be surprised how many times I have poured a gallon of gasoline into someones car to get it to start.
No start condition is the most frustrating problem. More information on what happens when you turn the key would help......but basicaly you need 4 things to make a car start. Fuel. Air. Spark. Timing. Fuel, Air, Spark and Timing are needed to start/run. Asked about fuel, but is the fuel getting to the cylinder? Do you have fuel pressure at the fuel rail(s)? When you turn the key to the "On" or "Run" position, do you hear a whining sound coming from the rear (fuel tank area)? That is your fuel pump priming the system. No sound? Check fuses and relays associated with the fuel system. Air. You need air to the cylinder to make it start and run. Check your air intake and filter. Really clogged and dirty filter? Pull it out and try to start. No go? Put it back (change ASAP) and look for Spark. Spark includes battery. Are there any loose connections to/from your battery? Really corroded terminals? Clean and tighten the connections. Try to start. No go? Pull the spark plug wire off an easily accessible spark plug (grasp the "boot" as close to the plug as possible and wiggle back and forth easily while pulling - these boots and wire connectors are fairly delicate). Remove the spark plug (be careful and dont break it or cross thread it when putting back in) and pop the wire back on it and set the plug on top of your engine (away from the spark plug hole). Have someone try to start the engine. You should see the spark plug fire its tiny bright blue spark. If not, you have found your problem. The problem is likely a bad coil, bad coil wire, distributor cap, rotor or a combination of these. If you have spark, then it has come down to timing. There are lots of things that affect timing in modern cars. There are a couple of sensors that jump out - Crankshaft and Camshaft position sensors. These will generally quit working while driving and you will likely notice the problem beforehand with it running really rough and getting crappy mileage, and the check engine light will come on and give you all kinds of hints. IF you turn the key and nothing happens, it might be a broken timing belt, but again, those usually fail under working conditions. It is possible (rare) the timing belt slipped/broke when you last shut off the engine, but I would point at the other 3 things first (Fuel, Air & Spark). Hope this helps. Good luck.
Your ignition switch is good if you are getting spark to the plugs. You need to find out why your not getting fuel through the injecters.Check your relays again . Do not crank engine over ,but turn key on and off 10 times to charge the fuel lines.But I think you need to check your wireing and get your instrument cluster working first.
start with the basics check for fuel fire and air check fuel peressure with a gauge should be 50 - 65psi
pull spark plug wire and place near ground if no spark in crank sensor or coil pack ensure air filter is cleaned
on fuel pressure if low check fuel filter pump may be working and cant get to fuel rail but could have damaged pump the fuel pump is controlled via crank sensor signal so no crank sensor signal no fuel
I would say replace ignition coil, that might me the problem, otherwise it can be the ecu, which might have some electrical problems not allowing the car to stay running. Good luck.
If you have spark and fuel (either via the injectors or spraying fluid into the intake), and still no evidence of firing, it suggests your valvetrain may not be working. If the valves can't open, the fuel cant get into the cylinder.
Do (or have done) a compression test. You may have a broken timing belt/chain.
check to see if you are getting a spark from the plugs. Just pull the plug and connect it back to plug wire. Then with gloves ground of that plug at the threds. Have someone try to start it only allowing 3-4 repatisions, and see if you have a spark. If you dont have a spark, then it would be eaither be the sparkplugs, plug wiers, or your coil is bad.
