OK. Yesterday I set out and installed my new OBX header welded to a Random Technologies 300 cell Cat. The install went OK, except that I lost one of the 8 header bolts and was unable to find it. So I finished up everything else, and figured that one bolt missing will be fine until I get a replacement. (would have been the same day) So I start the car and everything is running fine. I didn't even here a leak from the header. So I let it idle for about 10min or so to warm up while I put away everything, then got in and drove back down the street to my house, where I then parked and shut it off. About 1 or 1.5 hours later, I go back out to go to work, get in, start it, and it starts fine, then while its sitting there idling with me in it, I see the DSC light come on. I was a little confused so I tried to shut off the DSC light with the switch, but it satyed on. Then the rpms start to "choke" and slowly it faded and stalled. I tried to start it back up and, it started again, but then immediately stalled. I did this a couple more times, and the same thing kept happening. So I got a ride to work, and figured I'd try it again when I got home. So I get home and it was raining so I waited until the morning, where I tried to start it but nothing. Its cranking, and trying to turnover but it won't. So I pushed it down the road to my garage, and tried trouble shooting. I checked all the O2 sensors...all fine, check all the connections...all fine, also found the missing bolt and retightened the header. then I disconnected the battery to reset the computer. So I tried to start again, and no luck. I checked for spark, and I am getting spark, so I figure it must be something fuel related, but I just don't know anymore. I'm afraid I might have to take it to a shop. Anyone have any ideas as to what could be wrong?
Also, here are the specs on my car:
06 MCS Automatic
Just under 15k miles
Oil changed at about 5k intervals
Only use 93 octane gas\

Any ideas would be greatly appreciated!

 

I certainly don't mean to be a schmart **** here but I'm sure you have checked to ensure you have gas?

Is the fuel pump running
Do you have spark
Do you have a noid light, if not, might want to get one, they are cheap and it will tell you if the computer is firing your injectors.

Just a couple of things to start with,

good luck

YD

 

Thanks for the advice!
It sounds like my fuel pump is running, however I do not know how to go about checking whether or not I have fuel flowing.
I will have to look into a noid light as it sounds like a good idea.

 

Could you have messed up any of the cars ground wires? Do you have another battery you can try...

 

I definitely have power. All electric items are working fine. I'm unfortunately thinking that it may be the fuel pump...but really not sure yet
