I've got a 92 Camaro RS (3.1 V6), it started up perfectly this morning & now all of a sudden it won't. It's about 20 degrees outside here in Ohio & the car is parked on an incline, so I tried adding a little bit more gas to it, but no luck. I had the battery replaced a few days ago with a DieHard, the starter & alternator were checked at that time & they were all fine, I checked the fuel pressure release valve on the intake & it's getting fuel when I crank, I checked the coil to see if it was getting spark - & it is, I pulled 3 of the spark plug wires & grounded an old plug to the metal & I'm getting good spark there, but the motor keeps wanting to turn & it won't kick over. A couple of times it acted like it was going to start up, but it didn't. I have no idea what the problem could be....Someone please HELP!!!!

 

I'd still recommend putting a fuel pressure gauge on it. Even though you say it's getting fuel it might not be getting ENOUGH fuel.

EDIT: You might as well look at the Idle Air Control motor and see if it's sticking or broken....not likely but it's possible. If it's not getting air it won't start.

 

If the fuel presure test doesn't show anything out of the ordinary yank the electrical conection from the EGR and unbolt the metal hose that goes from the EGR to the intake. Then try to start it. Having the EGR disconected will set a code so you should check for any codes before you do this. In fact it would be in your best intrest, you may find the problem before having to do anything else.

If the car starts and runs after doing this your EGR is stuck open and need a new one. Allthough another easier way to check is to hold the gas pedel down 1/4 of the way and try to start it.

 

I've tried holding tha gas pedal down & then trying to start it - still no luck...I just replaced the EGR valve a few months ago too.
???????????????????????????????????????????

 

You didn't hold the pedal ALL the way down did you??? I'm pretty sure the car will go into "clear flood mode" if you do that. This will cut off the fuel so it won't start. Our cars might not do that though.......

 

When I worked on cars for a living (Firestone shop), I saw all kinds of cars come in as "no starts" when the weather started getting real cold out. These "no starts" fired right back up when new spark plugs were installed. It seems that old worn out plugs + cold weather = no start. Change the plugs, if that doesnt help, then at least your not out much cash. Try spraying some starting fluid in the intake too.

 

Thanks guys I fixed my problem. My Distributer cap came loose and moisture got up in there. Thanks for your help.

 

nice to see that it was a simple fix!!

 

So how was it getting spark when you checked it? Musta been some weak spark.

 

It had a blue spark when I checked the few plugs that night. Thats why I didn't think it was the distributer. The other mechanic I work with said It probably wasn't getting a consecutive spark. All I know is that it fixed it and that makes me happy.

 

Yeah your spark should be white not blue.
