The problems that Robert is experiencing is that the ECU does not recognize the chip. The car needs to be started with the chip in the neutral position, yet when Ryan and I went to troubleshoot the problem the car would only start in the "cold" program setting and would not recognize a change in "hot" and "cold" programs.... I unfortunately am unable to help Robert at this point in time due to the fact that he has had some work performed on the car(alarm, turbo timer, stereo install)that I was not present for, therefore making it difficult for me to troubleshoot someone else's work.... I say call the person who installed the electronic devices and have him/her come to your house as he/she obviously screwed something up. I personally beleive that an electronic device/connection has been fried as a direct result of moisture and not having a weather proof connection on exposed wiring/wiring harnesses

Demon, could the jumper wire in the ECU be fried as a result of the exposure to moisture? Just trying to think of all possible culprits. We checked the compression...190 across the board, changed the coil, removed the tapped in wiring from alarm/timer....what else could it be? Good Luck Robert!

The jumper is just two solder flowed points inside the PCM.
I don't see those ever "unsoldering" themselves without killing or damaging the PCM. (sustained voltage spike or the like)
Now a kill switch hooked to the PCM input/output off the coil pack may cause suck a voltage spike. (the PCM works with milliamps or less!!!)
Especially if it was unshielded. (i.e. highly prone to shorting from water!  )
I would go find who did this other electronic installation and ask WTF they did and why they did it so piss poor!!!
Until proven otherwise I would "assume" it's from this added on shtuff and how it was done.
The alarm/timer setup didn't mess with the PATS system at all did it? Like splicing wires or??? Another place for shorts...
I know if the installer of the TT didn't follow Stazi's write up that will cause problems. I know he ran across a few but don't remember what they were off hand.
That's yet ANOTHER part that is tied into the ignition system somewhere...

The car will start, as long as the chip is not in. It runs poor as hell. And on the S-AFC i'm getting absolutely no Airflow reading at all, usually i have at least something showing, and when i add a lot of gas at once, it'll start to bog but the continue to run with the higher rpms. It runs rough at idle and at higher rpms. You all can blame the wiring my guy did all you want, but if that's the case than how come my other CSVT didn't have the same problem? I think it has to do with the AFC, because i did at one point have a airflow reading and the car was running like it was supposed to. But from the looks of everything, if that airflow reading is not there, the car runs like sh!t. And any time i put the chip in, it won't start. Sorry if i sound a lil b!tchy, it's because i am. This has taken my stress level to a whole new thresh hold. My alarm guy knows wtf he's doing. So I'm pretty damn sure that ain't the problem. And the stereo isn't the problem, that thing is run off it's own battery. As far as the turbo timer goes, it's very unlikely that's the culpret. Right now, it's looks to me as if it's the AFC that has the car f-ed up.

Is the turbo timer the kinda that is hooked up to know RPMs to automatically set the time? If so, I bet it could easily be it. And did your other csvt have a turbo? No, so things are a lot different with this car, wiring included.

The thing is, with this case, that Alan had no proiblem like this before he sold you the car. Now you have had some extra electrical work done on it and nobody knows, not even you because you didn't do it, what happened at the shop or how "your guy" did everything. We all know by now that the PCMs are very tricky, sensitive creatures and if "your guy" threw some extra wires in there and now something's wrong, it looks a little obvious.....

But the alarm system has nothing different with it than it did with other car.
It's not like the guy who did my alarm is some friend of mine. The guy is a professional installer. And if it had a dirrect corrilation with those wire taps and moisture, then it would of shown up immediately, considering it rains pretty much every afternoon down here.
Regardless of the alarm and turbo timer, it starts with the chip out, but not with it in? Why is that? nobody seems to know, and i'm having to rely on other people for rides. This car is my main mode of transportation, hence the reason i had to have the turbo timer and alarm installed.

Sounds like the wires under the dash or attached to the PCM were damaged when this piss poor work was done.
The MAF reading on the S-AFC is just the voltage signal from the MAF. It's passed through the S-AFC so if the S-AFC is not getting it neither is the PCM.
You really don't want to believe it is this extra stuff that was added but more and more it's pointing directly at that!!!
Just because you took it to a "shop" doesn't mean it was installed correctly!!!
For instance I can bet you money they have NEVER installed a turbo timer on a contour before.
Also if they pulled a tach signal off he PCM it does not leave enough signal or the PCM to read.
There are just so many things they could have screwed up and the fact the job was done in such a piss poor way would indicated they are clueless (to put it nicely!)
Stereo is run off it's own battery??? It still has to be tied into the car's electrical system. What about grounding loops. Electronics hate grounding loops and your installer probably doesn't have a clue about them.
I still blame the installer at this point.
The S-AFC has built in protection but again a large spike or short can damage the unit and with what's been stated who knows what the installer hacked up.

Well it starts without the chip. It started with the chip until it was screwed with and rained on. Who taps the coil wire for an alarm or turbo timer using a scotch lock? I suspect the computer went out with the chip, but being 2000 miles away I can't say for sure.

Don't get a pisspoor attitude with people who are trying or have tried to help you...get pissy with the dipstick who obviously screwed the car up.
Just because you had the stuff installed and the problem didn't immediately happen does not mean that it is not directly related to the install(s).
That car ran perfect every day I drove it! The simple fact that you have beat the ever loving snot out of it(nearly new drag radials that went to absolute slicks in a matter of 1,100 miles) and have had some hack installs done, I'm not at all surprised that you're having problems with it. If you wanted an absolute bulletproof F/I vehicle you should have purchased a brand new Lightning with a factory backed warranty and left it completely stock. At that...if you had the hack jobs performed on that vehicle and had it towed in for service, the dealership probably would have voided your warranty.
Your peak of stress levels are self induced. Remember that....You need to be responsible for your own actions....When that clutch starts to slip because you have admittingly attempted to spin the stickiest drag radials known to man with a front drive and have been unsuccessful, don't cry to anyone about this and that.
I personally was shocked to see the compression so high after the car's apparent abuse since it changed hands!
Am I pissed off? Yes....sleep in the bed that you made, it's your own fault if it's uncomfortable!
