AU XR6 cold starting - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I recently purchased a 35km old AU XR6 that I am well chuffed with. However there is a small glitch that I have noted in cold starting, I suspect is probably quite normal but just want to check.

When starting from cold I never use any throttle, no injected engine I have ever driven has need it. However the engine starts and immediately reaches around 1500rpm then instantly die's. A restart works perfectly and the engine manages to maintain correct cold start rev's.

The problem never occurs once its been running for a couple of minutes, its as though it forgets to richen up on cold start and just flames out.

I am running 98 in it, and did note the problem didnt exist when on 91, this may or may not be a red herring.

Any idea's, or is this normal/reasonably common?

Hi mate, congrates on your purchase of an AU XR6, i can vouch that there a nice car and definitly fun to drive. I'm assuming your car is 35,000km.

About the startup issue, mine doesn't actually go to 1500rpm but on a few occasions it does stall or almost stalls then settles on the first start, but on the the 2nd start is always startsup.

Having an EF and now the AUII i've noted that it's possibly a characteristic of the EEC-V computer with the coil pack ignition. The EF done this as well slow startup but rarely stalls, but i suspect (not sure if my theory is correct) that since the XR6 has a warmer cam when it struggles to start it has a tendancy to stall over the regular 4.0L engines.

I think as long as it drives ok and the starting issue does not get any worse i wouldn't worry about it.

Your description is spot on and reflects what happens much better than I described, and yes that is 35,000kms.

As you say, I don't really mind the false start it's the driving that counts.... was more curious as to whether it indicated a problem or was reasonably typical, and you have answered my question.

Cheers

just my 2 cents worth check your plugs with they are black i bet my 2 cents that the coil pack is faulty another thing wrong with the AU.

i agree, try chaning your plugs first. I had the same problem with my AU. Once I changed the plugs she starts first time every time.

This problem has been brought up a few times. It seems to be an AU and AUII XR6 thing.

I had a brand new AU S pack and it started first time, every time. I then traded it in on a brand new AUII XR6 and found that every now and then it would stall at start as you described. After talking to others on this forum I found that it was a common problem with them.

I found that when you start it, just keep the key turned a second longer than you normally would and it should start first go. This won't hurt anything due to the failsafe system.

I also found after I drove down to Melbourne and gave the car a good run, it also would start first go everytime.

I don't have the problem any more since I fitted a performance exhaust. It might be because it is free flowing, though I wouldn't call that a cheap fix!

I think i'm going to get a new set of plugs for mine. I don't really trust the 50k life span of the plugs.

Anyway it can only do the car better and give it abit more

out of the engine.

A reflash of the pcm by local ford dealer should fix the problem.

My EL does the same sort of thing when i turn the car off with the A/C on. No probs if i turn the A/C off while slowing down to park

My dealer reckon's nothing's wrong with my car, they can't find anything anyway. My solution? When you turn on the ignition, wait until the ABS light goes out. Starts first time, everytime when I remember to do that.
