What's up guys?
I need alittle help here..... My tuck is acting alittle funny again. It's been running great for months with the NEW Ford motorsport mass air conversion kit. But yesterday I took her out for a 15 min. drive and parked it for approx. 30 minutes and when I went to start her it just wouldn't ignite. I turned it over and over and finally she fired up. It idled fine then stalled. I did that five times in a row. It almost felt like someone was under my hood and pulled my ignition coil off while it was running . It would idle nice and smooth at 800 rpm's then just cut out. The engine didn't bog or chug. It was just like someone turned the key off.
I hope I'm making sense here. Any suggestions guys......ignition coil, ign module, computer, bad ground?
Any suggestions would be very appreciated.

Is it a dual tank set up? Mine was doing this 2 weeks ago. It wouldn't start properly. Turned it to the rear tank and it was fine. Turns out it was my front tank pump.

Good luck!

Yes, it is dual tank.
You might be on to something here..........

Thanks,

 

It's hard to explain.......It doesn't feel like a fuel problem.
It will run for a couple of seconds and then cut out....just like I turned the ignition off. And as it's shutting down the atermarket tach will jump around like it's on crack.

Merry Christmas ........lol.......too funny . tach on crack .......lol

 

LOL! "Tach on crack". Too damn funny!

Have you checked for codes? If something is disrupting the ignition signal, the ECM probably is aware of it, and is just dying for you to ask it about it.

Also, you could try this: Start it up in your garage/driveway, and grab a hairdryer. Plug it in, turn it on low, and point it at your TFI module. If the engine stalls within two minutes, the module is bad. If it continues to run after two minutes of pointing the hairdryer at the TFI, the module is fine. Either way, don't exceed two minutes with the hairdryer.

Take care,

Thanks guys. I'll give it a shot.

 

I finally got around to changing the TFI module. I couldn't get a hold of a Ford TFI so I went to the local auto parts store and bought a WELLS TFI module. (Part# F121)
Has anyone used products from this company before? This is a first for me.

Anyway, I think this did the trick!
So far so good.........

Thanks for all the help guys.
