Now it wont even start

The cam shouldn't be the problem, cause the Trick Flow stage 2 cam is still streetable. I think your problem will be with the 80mm MAF meter. Though trial and error with a friend of mine, we concluded that the 80mm Pro-M meter she had wouldn't even work on her car, but my 75mm Pro-m worked just fine. Also I have heard numerous people having problems with sample tubes in their MAF meters, that's why I prefer Pro-M. Each unit comes with a calibrated sensor for the correct injectors.

Would it be possible for you to put back in your stock 19 lb-hr injectors and stock MAF meter? Just bump your fuel pressure up to about 50 psi, and see if it runs then?

Oh yeah, I forgot to add to reset your computer after every change like Mendari said.

Oh and please make sure to include Cam Lobe Seperation. If you give me this info I will try to call the boys at Anderson Ford through my work. They will give me some good ideas to help you out. I wish I could help more but I have no real world expirence about the Tweecer. Because AEM is taking forever to come out with there unit for the Mustang. I may go Tweecer to so I'd like to learn about it also.

hiflow50, as far as ive read pro-m only calibrates there mass air meters up to 36# injectors?

Sorry for being confusing. I meant that you should check the throttle body for movement, make sure it opens, closes and that the cable has the right amount of play. It sounded as if the engine might be starving for air.
For the alternator, the battery will supply power to the starter motor but after that, the alternator sends electrical current to your ignition system/spark plugs. Just make sure that your alternator is producing enough electricity to keep the plugs firing properly.
So far however, the MAF seems to be the favoured suspect.

#1 The TFS 2 Cam shouldn't be an issue with stock MAF.So my guess was wrong thier but I will still ask Anderson Ford
#2 Are 42lb injectors low impedance? I can't remember but for some reason I think they are. If they are that is your problem right there. But some1 needs to confirm this.

This is a good point as well.

Also, why do you feel the need for 42 lb-hr injectors? Do you have future plans for a power adder?

[stang_racer20]

well i thought about 36 pounders, but i got a great deal on these. i got the set of 8 steeda 42# injectors for $300. Plans for power adder, oh yeah! Either a Twin Cartech or PTK Turbo Kit.

I just dont understand how 'just like that' for no apparent reason it wont start now. It boggles the mind.

[GTStang]

If your 42lbs injectors are low-impedance injectors that is your reason right there. Low-impendace injectors will not work on a stock MAF computer set-up correctly. It will run somewhat but the amounts of fuel you are gettin is all messed up. I think your Tweecer can handle L-I injectors but it needs to be set-up for them. My research will continue

[stang_racer20]

does pro-m make a 80mm bullet for 42# injectors?

maybe i should just switch and see what happens. plus i talked to my engines teacher today and he mentioned several things for my car i never would of thought of to check out. i'll try those any see what happens and then post back.

[GTStang]

Ok I talked to the boys at Anderson Ford today. A lot of your problem with the hard starting is the #42 injectors. They are not low-impedance but the are pushing the limits of what a high-impedance injector can do. Most people who have #42 injectors will have a tough time starting thier car. Anderson's PMS has a special fuel start-up setting for starting a car with #42 injectors. But we are trying to figure out what exactly to do with the Tweecer.

A seriour problem you got Stang_racer20.

Listen, might be a stupid suggestion but this is how we "Ukranians" start our Lada's, try to start the car from a roll (you know, call your friends and tell them to give you a push) and then check the engine while its running.

[stang_racer20]

what type of setting are you talking about GTstang. like a different startup fuel table for the tweecer?

the car is an auto ssdisabled, not a manual. and it still wouldnt help any if it was.

Yea one especially for using #42 injectors which are causing all sorts of problems when starting cars.

[stang_racer20]

u say anderson ford has a table but not for the tweecer?
