Hi guys
I got a problem that has got me completely stuffed.
I gave my El Falcon a oil and spark plugs change and I fixed a leaking exhaust manifold with a new gasket. Car started fine so I took it for a spin around the block and when I got home it stall and backfired in the driveway and I haven’t been able to start it since.

So far I’ve changed.
Leads = new
spark plugs = new twice
rotor button = new
dizzy cap = new
Tfi module = 2nd hand
map sensor = new
tps = 2nd hand
isc solenoid= 2nd hand
fuel filter = new
coil = new
Battery = new
Put the stock exhaust back on as I thought maybe my cat converter was blocked on my extractors

It has spark and has fuel. It trys to start but as you stop cranking it almost starts and when you hold the throttle wide open it back fires through the throttle body. I’ve use a Lead light to fault test of the Diagnostic plug and it comes up with 126 MAP Sensor out of calibration.

So any ideas on how to fix this?

Any help would be appreciated

cheers Steve

Make sure vacuum hose to MAP sensor on firewall is still connected both ends (usually will not stop them running though)!!

I would still suspect TFI & hall effect sensor. Had the same issue years ago.

so it turns out it is my Auxiliary shaft has a bunch of teeth missing.

my question is how hard is it too replace the Auxiliary shaft?
or would a be better of getting a 2nd engine?

cheers steve

have a read of this-http://www.fordmods.com/ford-4l-and-6-cylinder-f1/engine-rebuild-parts-list-cost-requirements-information-t107383.html

thanks hans
looks like a 2nd hand engine it is

drop a 3P package from one of our sponsors in. Barra low k's conversion job

which sponsors is that?

cheers steve

Interesting, I thought CMS or it was another sponsor that doesn't appear to be here any more?

I think CMS where building a 4.8 i6 & there was talk of a '3P' crate thing from somewhere. It involved a Barra motor conversion with everything you needed to get a barra in to the front of an E series

Yeah I didn't a search but it looks like the CMS forum has been deleted/moved.
I a quote from heinrich performance here in Adelaide he wanted 4K to do a FG conversion
or 3-3.5K to do a BA conversion.

so i think i'll just get another EL motor

yep... cms is no longer a site sponsor....
