Issues with my Fox-Symptoms inside......

[ShawnQ]

Has the ignition switch ever been replaced?

It's pretty easy, pretty cheap, and can cause similar issues. I had a car that the fuel pump wouldn't prime/energize with key on. You had to hold the key to 'start' (which also cranks the starter) in order to get the fuel pump to run. Ended up being the ignition switch.

Good catch Shawn...

So you got a new ECM right? Was it an A9L, A9P, ??? Salt and pepper shakers good and tight? You might try taking them apart and inspecting for corrosion.

Second hand A9L
Salt-Pepper are next on my list, thx

Hmm, never been replaced.
Thx, will keep in mind.

Yep, under the drivers seat. It could be on the fenderwell depending on what year it is though.

It depends on the year, if I am not mistaken its either 88 or 89 for the cut off then it went on the passenger side fenderwell. The pump stay on is a common symptom for those switches. Check the fenderwell before taking the seat out. Trust me on this.

'87-'91 is under the seat, '92 & '93 it's in the engine compartment.

Thanks! I was thinking it was the other way around... I couldn't remember...

You said you have two pumps? Are they both stuck on? Are they both wired together or is the second pump on a different circuit? Also what dizzy did you replace it with ? I had one from a parts store do something very similar right out of the box not long ago. Did you spray the engine with water at the car wash? You may gotten water in the salt&pepper connectors etc. As far as the maf goes just unplugg it fo a crude test. If it runs better unplugged it could be a issue.

if I'm not mistaken the TFI module can cause all the issues you are having as well. I would bet that's the issue. Did the new dizzy come with the tfi?

Second pump is booster pump on separate Relay but switched on from main,
As for the Dizzy it's a new one from O'Reillys I think Canadian brand Rich Porter technologies, can't find a stocker.
Did not wash the engine
Gonna try the MAF test in a bit thanks for the tip.

Yes new Dizzy came with the Module I have some spares I can try.
Thx

Before my back gave out today
Unplugged my MAF no change
Unplugged my second-booster pump no change although
intank pump sounds different hard to describe almost weaker sound
than before.
then my back got hurt...
Gonna try another stock dizzy I found.

Maybe just me, but, I would stop guessing and check the codes: http://www.dfwmustangs.net/forums/showthread.php?t=7908

Thanks! will give this a shot
Will I get an accurate read even though I have a custom chip?
Reason I ask car runs with "Check Engine" light on constantly
due to the minor improvements made to the polution control system
and other areas..

84
96
Found loose MAF Pigtail connection fixed
same as before 15 replaces 96
But wait it get's stranger, before i did anything today
I switched chip position to "Stock" fired up smooth stayed on for about
5 minutes then it died, unable to get it going again.
It does attempt to fire up in the Motor tune but NOT SMOOTH

[Diabolic]

I don't think the "stock" setting is even stock. NO way that thing fired off without the chip. You would be flooding the piss out of it with 60# injectors. I would think the chip was to control the larger injectors. I'm really not even quite sure how it would be able to run at all with a stock tune setting. It would be running super rich with 60# injectors.

This all occured at a car wash... Did you wash under the hood?
