a question I have a 2000 firehawk, and i just recently put a pair of JBA shorty headers in place of the stock exhaust manifolds. I have read the threads on AIR and EGR removal, and followed them. when i put it all back together a few days ago it would not start at all, the engine does not even turn over. I haven't had it retuned yet because it wont even start. I checked everything, (spark plugs, starter, battery) and im vexed as to why it wont even fire. I was under the impression before i had the codes deleted it would just run like crap, but it wont even start. I dont have a means of tuning it myself, and im not real knowledgeable on the diagnostic codes and tuning these cars. If someone can give me an idea of why its doing this, i would be deeply thankful, i am leaving for the military next month and i gotta get this thing moving. I appreciate your time.

post exactly what you did so we can get an idea of what's going on.when you say it is not firing, does it crank over and not start or nothing happens when you turn the key?

Sorry i was in a hurry. Yeah it doesnt do anything when i turn the key. and when i turn it back to 'off' the gauges jump and go back down. if i have the door open when i do it, the anti-theft little red light flashes and clicks rapidly.

well i started by disconnecting the battery, then i took the air dam, and bottom covers off, unbolted, and unplugged the AIR pump. Then proceeded to take off the hoses that run to the manifolds. After that, i unbolted the EGR bracket, removed the tubing that connects to the intake manifold and the exhaust, took that out. Then i unplugged my coils from my spark plugs on the passenger side, took the coils off to make room to get the manifold out. I took out the manifold on the passenger side, after i had taken out all the O2 sensors. The i took off the coil plugs from the driver side, then the plugs themselves, then the manifold. then i put the driver side header on, with new gaskets, then i put the passenger side header on. i put all the O2 sensors back, put the coils back on the one side, reconnected my wires to all my spark plugs, and blocked off all the holes in the headers where the EGR and AIR would have been and then i put a freeze plug in the intake manifold. This was over a period of about 3 weeks because i had to reorder headers. I charged the battery thinking it was just dead, but its fully charged and it doesnt do anything still. i looked and made sure all my wires were reconnected, like to the coils themselves, and from them to the plugs. The wires that were connected to the AIR and EGR are still on the car, and i just taped them up and made sure they were out of the way. Other than that i did not mess with anything else.

it could be your alarm is armed and preventing you from starting your car. also, lots of times your ignition key can get damaged and the pcm will not recognize the key. the same thing happens to the ignition lock and cylinder. if you have a spare ignition key try it. check to see that you tighten the battery cables correctly.

i haven't tried jump starting it, but i double checked the battery, i charged it twice, and used my meter to check it out, and it was good. im starting to suspect the anti theft system, because when i switch it to on mode, it turns everything off, even my dome lights, and the security light flashes and clicks. i switched it to accessory mode and the radio didnt even turn on.

ok i tried that, didnt work, but before i could disconnect the battery, the parking lights came on, like it was working normal, then i tired to start it and it shut all of again. also, when i put it on 'on' mode i hear a buzzing sound coming from my driver side fuse box, the one with horn, and the fan relays. and when i shut it off there was a knocking noise from somewhere in the engine bay, so i disconnected it.

my car was doing the same thing the other day, excpet just not after an install.
Sat there for 15 minutes trying to get it to start checking everything i could think of, they I pressed the unlock button on the key and bam it suddenly worked. The Unlock on the door did nothing, but the one on the key did the trick or some reason.
