Can you crank the engine? Does the starter work?

If yes, do you have a chip or flashed ecu installed?

I called you this morning to see if you want me to swing by and make an apperance. I guess you could use a fresh mind after not getting much sleep if any at all. :)

dude that would be awsome im missing something dumb and i just cant see it. plus i broke my finger and the bone is getting ready to pop through the skin:blackeye:
 
so you used a SVT harness on a straight 3L? what did you do about the fuel injectors? did you splice connectors? maybe one of the connectoins you had to make to splice injector plugs or to extend wire for the other items is shorting out or isn't good. that would cause a no start.

but i should still get crank right:shrug:

depends. there was a local member here who spliced in a new tps sensor connector. he got a no start conditions because the wires where shorting out. now I don't recall if it wouldn't crank but the ford dealer testing the car said the pcm was bad. When testing if they moved some of the harnesses it would work correctly and they could connect to the pcm.

So I am thinking if you spliced something and for soem reason it shorting out, etc it might cause this issue.

So without a key in the ignition, the fuel pump energizes and the CEL comes on?

A shorted VREF can cause a no crank. Did you rewire anything that had a VREF in it?

What's the condition of the battery?

yes, no, good
 
Try this, take off the connector for the engine wiring harness by the brake booster and try to crank the engine see if it will crank
 
figure it out, the ground to the clutch position sensor was dead:shrug: grounded to a new source and whammo:cool:

ROFL.
 
Yep. Eurotour had that issue. We couldn't figure it out. He traded the car to Steeda. LOL! It was his black one. He figured it out in 10 minutes. Doh!
 
false hope:cry: pats light will flash when reset by removing negative cable but stops when i turn key onand stays off till i reset again, no fuel or spark? anyone:shrug:
 
sounds like the pats, or PCM is RETAINING power after you turn the ignition on and then off. The pats does a 1 second illumination (prove-out test) when you turn the key to "on" the first time?

afterwards it goes off completely?

Does anything else seem to have ignition power on the car after you turn it off?

Test PCM power wire leading to the PCM or alternatively test the PCM power relay for an output:
after you "reset" the car
after you turn the key "on" the first time.
after you turn the key off, afterwards...

Does power to the PCM go away after you turn it "off"?
