2-5 is closet to the drivers side. Go by the decal on the radiator support.

I've had my bird sit 8+ months without a single issue. Fired right up and I used the rest of the gas in the tank without issues. Didn't have a choice. When Uncle Sam says go, you drop everything and go.:(

Then what do I do now? If fuel is OK and Im getting spark, engine wont even stumble unless I spray in starting fluid, what now? Injectors? If so?

Re: Im back! And with a 94 Camaro ~ need direction!

If the car wants to start when you spray starting fluid most likely its a fuel problem. Is your fuel pump whining when you turn the key on? Are your plugs wet after you try and crank the engine? If they are wet smell the gas on the plug if it doesn't smell right you have to change the fuel.

Fuel has been changed with additives, new fuel filter, still nothing. And when the fuel filter was disconnected we checked to see if if the FP primed, no issues there. I also checked to see if there was pressure at the relief valve and noticed it only had pressure if I did it right after trying to crank. A closer inspection revealed that the valve was leaking, so that was also replaced.

But now I believe there is reason to suspect the PCM. For the hell of it I decided to check to see if I could pull some codes. I know I had a good connection, jumped A+B terminals, it is the 12 pin so I know its the right procedure. And I couldnt even get a code 12! It did nothing, the SES just stayed on! So is it the PCM???

Are your plugs wet with fuel after you try cranking? If not then your still not getting fuel?

Re: Im back! And with a 94 Camaro ~ need direction!

If the plugs are not getting wet and Im getting the fuel to the valve, then it would have to be injectors right? If this is the case then what do I do?

Re: Im back! And with a 94 Camaro ~ need direction!

Ok, the plugs are deff getting wet....

So for the hell of it, while the plug was out I decided to check the spark again. Now I noticed instead of going between the center electrode and side electrode, it goes between the center electrode and insulator tip... So what do I do now?

Re: Im back! And with a 94 Camaro ~ need direction!

Never heard of that! Does it do that with all the plugs or just that one?
If only that one then replace it. It could be cracked from removing and installing. Check the porcelain for cracks.

I tried four different plugs on the same wire. Although not new by any means, but they all did the same thing...

At least we know its a spark issue now...

Anyone?...

Re: Im back! And with a 94 Camaro ~ need direction!

When your checking for spark do you have the spark plug grounded?

To the intake, very well... I know the intake shoud be enough.

Even then, what would it be then? Im getting fuel to the plugs...

Re: Im back! And with a 94 Camaro ~ need direction!

Did you check your coil packs to make sure there good? You should check your fuel pressure reading also. It's best to check these things first before throwing money at parts. I did have a problem once with my car starting and running and it was the map sensor which is mounted to the passenger side of the upper intake. Check to see if the vacuum lines going to it aren't cracked or disconnected. The vacuum line is shared with the fuel pressure regulator.If the fuel pressure regulator leaks it will send fuel into this line. Something else you can check for.

weak spark

what color was the spark when you were checking it?
