wiring up a 2.0 zetec
steveyb - 16/11/09 at 11:37 AM

Has any one on here wired up a 2.0 zetec engine from a 1995 ford mondeo using the standard brain and fuel injection system?
I have fitted one to my sierra but I can’t get it going. I have it wired up and turning over but there’s no spark so it wont fire up.
The wiring of it has the PATS but I have the transceiver and chip key. I have it wired in with a status led but it keeps flashing so the immobiliser is not switching off.
I have been talking to big_wasa regarding the wiring and he’s been a great help. I have it wired up but what could I be missing to stop it from sparking?
I think it’s because the immobiliser is staying on but I’m not sure. Has any one had the same problem?
Ecu is TELL if that makes any difference?
Thanks

have you only got the one red ford key? as sounds like the PATS imobiliser, does the fuel pump run or is it just lack of ignition, not sure if the PATS imoblise's just the ignition or fuel pump. does the led flash at constant speed as there seems on this web site some diognostics if you leave ignition on for a couple of seconds. hope it helps
PATS system

yea i only have the red key.
i have the fuel pump wired direct for now.
yea it flashes constant then does intermitting flashing i'll need to check which code it is refering to.

ok thats the power for the pats

pin 5 must be the white / green

steveyb - 16/11/09 at 07:36 PM

yea pin 5 is white with green line.
i have wire from the pats (yellow/green) to direct 12v. do i need to move it to pin 41?

Its how its done in the car.

Its perm 12v not switched.

That and pin 1 orange need a perm 12v

The key needs to be in range before switched the ignition is on.

The Immobilizer led should stay on for 2~3 seconds then go out.

If it does not read the key it will flash rapidly.
