yea autozone trys to sell you the fox pip and will argue with you and tell you its correct. some other fords had the same pip, i dont know which ones though. anyway did you check your coolant temp sensor? may sound weird but i heard that has something to do with only starting at wot ...

As you know, cranking the car with the throttle at WOT kills the injector pulse. Are you fouling plugs?

If it is an issue related to your nice Turbo set-up, that is gonna go beyond me.

Good luck.

first of all, hissin, i cant thank you enough for all the help.

No, it has nothing to do with the turbo setup, as it was running great after i got my dyno tune chip, and it just started acting up.It hasent fouled any plugs, but it just dies and wont run for crap out of nowhere.....and its definatly getting plenty of fuel, its belching out rich-burn ur eyes smoke as it runs. Honestly, im at a brick wall with what i should replace/test next. So, the car stis in the garage still...

Do ECU's generally go bad? When i remove the chip, i really dont get any ecu codes.

Please help?!

Click to expand...

there is a memory location that the ecu checks to see if the rom is "ok" or not. without a chip, that memory location is supposed to have the value 8192. in the tweecer, it is called the "checksum base address".

anyway, chips are supposed to set that location to 0, which disables the checksum checking or maybe it tells the computer that it is a custom calibration, something like that. i wonder if maybe your chip doesn't have that location cleared, which is why it spits out that code.

MAF.

I didn't have mine connected when I first got and started working on my car and in order to get it running I had to keep pumping the gas to keep it running.

Just a thought.

... a PIP can be bad at any time. It generally does get funky when hot, but it is not as heat-related as a TFI. Sometimes a hot PIP will allow the car to start back up and sometimes even after it has cooled, it still wont start. TFI's often come back to life once they cool down. TFI's can also allow a high-speed misfire as they are on the outs ....

yeah, i was incorrectly lumping the pip in with the tfi.

Today i took apart, cleaned, verified, anit-ox'd every single connector in the engine bay. No help.
I checked the timing, spout out, 10adv....perfect.......No fuel is coming from the FPR vac line.......
As the last thing i tried, i war barely able to get it running.....and with it belching eyeburning smoke, i put a scantool on it, and went into monitor mode, and i saw when i plugged in the MAF, it went from 0 volts to 5.....because it wouldent start with the MAF plugged in.

So, im thinkin this may be the problem....how can i check a maf? Its a Mass Air systems Blow through, and it wasen't cheap.....maby they can help me>?

i read almost every post you put out green, your lack of fear for tearing into your stang amazes me. i am gaining the courage needed to tackle my next projects thanks to you and a lot of other guys on stangnet.

so this is a real (stupid?) suggestion: have you tried clearing codes? i dont think i read anything saying that you disconnected the battery and let the computer forget everything. maybe if you try that w/ and w/o your chip, with the spout on/off, whatever.... i see you think your MAF is shot, i thought that was one of my electronic gremlins keeping my stang off the road for the whole summer. it was something inside my dizzy, i ended up replacing everything ignition related (all mallory hi-fire vi) until i got to my dizzy. once that was replaced the stang woke up and terrorizes the streets of new england. i have the saleen heat extractor hood so i think that water got into my dizzy during a storm, the vents let water go right through.

good luck man, i want to meet up with you some time im not too far away from the cape (hingham, ma). i want a ride in that tt stang, im just afraid that if i get a taste i may have to follow your lead and tt my stang as well
