When it doesn't start, you need to find out if it's spark or fuel. Start with spark. Get a cheap spark tester and put it inline with a spark plugs and wire. If you don't have spark, we can help you chase that. If you do have spark and it still isn't starting, check fuel pressure. If you have both spark and fuel pressure, it could be an issue with the ECU not letting the injectors fire. There are many things it can be, but you will have to gather the requested info when it doesn't start.

What spark plugs are you running? Did you look at the cap and rotor? Coil?
As for header, I am running a Doug Thorley. Some like the Banks. I just received the 'cat back' system from Iron Rock. Also, the ignition module up by the key, might be an issue. Also, replacing the injectors might help it run better. The Ford 4-holes are a good inexpensive solution.

was looking on iron rock what cat and muffler the o2 sensor plug is not on the cat on my stock exhaust wouldn't mind the magnaflow just want to know which one along with the muffler
thanks
the cap rotor and plugs were replaced brand new by previous owner less than 2k ago but I'll check all out

How was your fuel filter? If it has ever been run without a filter or with a very plugged filter it doesn't take much to plug the injectors. Obviously first check your spark and air but plugged injectors are not uncommon.

thanks mongolchuck when I can I'll be sure to check the injectors changed the filter and it runs better and starts up i will be looking into purchasing the 4 hole
any suggestions on type or part number
thanks brutha

Did you check the battery voltage? Battery cables? Voltage to the PDC (Power Distribution Center)?
