Im having a hell of a time getting my taurus back on the road.... its a 3.8l with 93,000 miles on it. it was working fine up until a few days ago and the air bag light started blinking 4 times then a pause....then once..... then 4 again...then repeat. but it still ran and drove fine so i figured this weekend i would look into it
Fast forward to today we went to get some food and came back out....and it wont start... it tries to, but i cant hear the fuel pump priming. there also is not any spark....none of the warning lights come on and all i hear is 5 beeps then a pause...... 5 beeps then a pause......5 beeps then a pause......then after the 5th round of 5 beeps it stops.....but still it wont start (guessing because no spark and no fuel lol)
What would cause the car to beep 5 times? now the airbag light dosent come on at all when i try to start.... is the brain fried or something? this is our daily driver and we have 3 kids.....its allways 1 step forward 2 steps back
Well, everything else works.... the power windows work when i turn the switch to "on"..... the blinkers still work and the engine tries to start when turned all the way.... but for whatever reason its not shoing any lights in the cluster and i hear 5 beeps from the passenger side dash....
This is killing me i cant find ANY answer on the web......and ford wont tell me anything without actually seeing the car ....
Im a decent mechanic and im good at trouble shooting but this has me stumped.....every fuse in the car is good ive checked each one under the hood and under the dash like good ol saint nick lol
What gets me..... i usually when you turn the key to "on" without starting.......the check engine and low oil light come on untill i start it, but now im not getting any gauge cluster warnings at all......just 5 beeps from the dash. it tries to start but im not getting spark or fuel....
Is it in any way possible that an SRS failure could caue the vehicle to not give any signal to the ECM? the fuel pump does not prime nor am i getting spark at the plugs.
i dont know if this will help.....but we just bought the car a week ago.
The radiator fan is hard wired into a red/green wire by the harness plug at the driver side of the engine bay. Its wired in a way that when i turn the key to "on" the fuel pump used to prime and the rad fan would spin.......what wire does this control? could the previous owner running a 30 amp fuse to the fan off of that wire caused a problem somewhere? there is no melting or anything. and now when i turn the key on i dont hear the fan or the pump prime....
so im assuming the red/green wire is a switched 12v wire? but why is it not working now?
Damn that's a mouthfull!!! OK, code 44 was Center Cowl Primary Crash Sensor Mounted Incorrectly. If the Crash sensor on the cowl is loose, or has corrosion on it's mounting point will cause this code. With the battery disconnected, unbolt the sensor, scrub the cowl with a wire brush, and the crash sensor mounting bracket. Reinstall the sensor.
However, you have the airbag diagnostic monitor now beeping 5 times:
If a system fault exists and the Air Bag Indicator is malfunctioning, an audible tone will be heard indicating the need for service. The tone is a series of five sets of five beeps. This DOES NOT indicate a diagnostic trouble code 55. It means that the indicator is out and a system fault exists that requires service.
Inoperative Lamp Circuit or No Ignition Voltage to Diagnostic Monitor
The air bag indicator is designed to light for 6 (±2) seconds when the ignition key is turned to the ON position. This initial 6 seconds of air bag indicator illumination (continuous lamp) is considered normal operation and is called "prove-out" of the air bag indicator.
The diagnostic monitor requires power at Pin 1 in order to energize the air bag indicator circuit. If the air bag indicator circuit is open or if the diagnostic monitor does not have ignition voltage at Pin 1, then the air bag indicator will not light.
A No Air Bag Indicator condition can be caused by:
A burned out bulb or open wiring in the air bag indicator circuit.
Loss of ignition voltage at Pin 1 of the diagnostic monitor.
So... you may have an ignition switch issue causing a loss of key on power to the airbag diagnostic monitor.
Now, the no start issue. The last owner must have jury-rigged the vehicle to run because of a bad Constant Control Relay Module/Intergrated Relay Control Module (CCRM/ICRM), which combines the PCM power relay, the radiator fan relays, and the fuel pump relay. The CCRM is a common issue, there also can be corrosion in the CCRM connector. Take a picture and post it on here to show where the Red/Green wire is. The CCRM is under the warning label shield, next to the front crash sensor. Make sure the ground wires on the radiator support are tight too.
