Car will just crank.

[Cynxe]

Yesterday it took awhile to get my car started. But i did get it started, and i drove it. I got it home and parked it, and hour later i went outside and started it, it fired right up. Now its the morning and it just cranks, no starting.

You most likely flooded your engine +1 for check your injectors out ohm them and see what the ohms are and use a continuity tester to check and see if the injectors are stuck open,

Next time your car won't start remove all plugs and clean them off u can get a spark plug cleaner for cheap to but( ragg works) after you dry them off I bet it will start went threw this when my cts went out causing this exact issue you gotta be patient when the car won't start so you don't flood it

If it does start check your cts when the engines hot and after its bone cold and compare to a good cts resistance

Is it possible that the cas can be causeing all my misfire?

It is possible that youll figure out your issue if you do all the things that have been mentioned

Stop wasting peoples time and go out and work on your car. You need to check fuel pressure with an actual gauge and not just by pulling the return. Check compression to see if it holds air and if you have spark. Its the basics(air, spark, fuel). If its a coolant temp sensor check the resistance to see if its good. Dont just buy and replace unnecessary parts.

If you dont have tools or knowledge to diagnose things then take it to someone who does before you damage the car. Judging from your other thread you dont even have a $2 spark plug gap tool because you just "bent" the electrode back after you dropped a plug from checking it.

The more thorough job you do and more information you give us after you've done the basic tests(PROPERLY) will allow us to better recommend a fix.

I replaced spark plugs with new properly gaped ngks, it started right up. But during idle it has bad misfire. I shut it off and changed the coil, still bad misfire. Im getting fuel, my injectors are fine, my compression is fine, and my fuel pressure is fine. I have spark, i pulled the plugs and it had good spark. I am now stuck with plug wires, or the cas.

Drive it around it might go away if the ecu was reset unless the misfire is bad but you might as well change the plug wires just in case

i did drive it around. but the misfire didnt go away. what happens if its not the plugs haha?

 

[Cynxe]

when i get up to higher rpms, the misfire stops

How do you know injectors, fuel pressure and compression are "fine"? What method did you use to test these items?

 

[lasthope05]

Check resistance on plug wires/ look for arcing. How new is the gas? Usually a CAS is not problem if the car is starting and running.

Also whats your fuel pressure/compression numbers, resistance of the coolant temp sensor..etc. You're not telling us anything by saying everything is fine.

To tell you the truth your going to have to try and see how it runs with new plug wires but if that's not a fix then return them if you can and buy a fuel filter Instead

But if fuel,compression,spark is all good I'd swap a differnt known working ecu in it have you checked timeing?
Do your marks all line up?
Did you try an unplug the maf?
If your really out of options trace through all your wiring and look for broken wires (fuel injector plugs , cam sensor,cts ect..)

you can even try and and see if your power transistor came out of the socket a bit the wiring is really tight and can shake loose but usually you loose spark in 2 cylinders when that goes out ,
what ohms are your injectors seeing?
Do you have a logger?
Lots of stuff to check so this should keep you busy for a while it's always good to test twice when your trying to find the root of your issue , keep me posted

All in all I bet it's your injectors if plug wires don't help what's your ohms? test twice , also a good idea to check the injector resistor pack but I'd doubt it's the issue

I did a leak down test at my college here. All cylinders in 150psi range, and pressure held. I haven't done the fuel pressure but i pulled plugs while it doesnt start. And its wet and i can see fuel on the pistons all cylinders. I was trying to change the fuel filter but the bottom fitting is coroded into the old filter and i cannot remove it.

So...youre having a starting issue again?

 

[Cynxe]

yes :/ Im beginning to think its that stupid coolant sensor, I get spark on every cylinder, good compression, and fuel. it just makes no sense. I want to change the fuel filter for good messure but the fitting on the bottom is impossible. Earilier it took upwards of 2 hours to start and when it did it lasted for about 5 seconds and it sounded like it was going to stay at idle but it died. I did this about 4 times and then it went back to regular cranking.

Yea...you should have probably put a new one in the first place....I mean..you do work at O'Reilly

I want to clarify, that i bought this car a month ago, It sat for 2 years. The transmission was blown to peices. I spent hours and hours on my time off swapping trans, I just recently started it for the first time last friday. I wasnt aware that that sensor was bad in the first place. I understand that after sitting for 2 years it would take a bit of effort to start. If i wouldve known before hand that the sensor was bad, yes i wouldve replaced it.
