F40 Starting problem

Don't keep cranking a motor that will not start for long periods of time. You're washing fuel into the engine, past the rings into the oil. Have it towed to your service place. Smell the dipstick and if you smell fuel get it the oil changed. You can also damage the rings if you don't stop.

It could be a number of things hopefully not major.

Good Luck

Cheers

 

It's not sparking, tow it to the dealer.

Who services it for you? I like using Dick Lovett in Swindon

Best of luck

 

couple of turns of the crank is not going to cause bore wash so dont panic. Over years maybe but not just a few times.

Sounds like primary ignition, probably a dry or loose/corroded/damp connection, especially with the weather we have been having, otherwise at least one bank would fire as they are run by separate ecu. It will be a feed before these no doubt.

Not sure if they use a shared crank sensor on the F40 but this is often suspect on other marelli equipped engines using the same ecu.

First thing to do is move/twiddle etc every connection you can see in the engine bay before sending it off to the dealers.

 

I wouldn't mess with it. This is happening for a reason that needs rectification/repair by the dealer after checking it over. If you can somehow get it started, you run the risk of this happening again somewhere inconvenient.

 

Then get onto the phone with Alan first thing in the morning.

 

Its a late 80s car, no different to any other, dont be afraid of it just because its worth a lot of money in comparison to other late 80s cars.

They were all made of the same basic components, ferrari mechanics are no different to any other mechanic, they will go through a checklist just like one thats fixing a humble fiat.

If your not mechanically minded then steer well clear regardless of the type of car but if your are practical then you wont do any harm trying to isolate the problem area yourself first.

 

Wow, all that trouble for that, thankfully it was just that. I will check in the morning if mine has that switch. Haha these things happen at times

 

Ugg..I've been stung with the same type of thing a few times. You knock your head against the wall for hours over stuff like this. Worst part is, you feel like a complete dolt afterword's!!

 

Glad that its resolved now, enjoy your F40 in best of health.

 

Hey, it could have been worse! It's a good thing it was just a kill switch. I didn't know they had them...

 

Haha. At least it was nothing but lost time.

 

According to the diagnosis...the kill switch is disabling the fuel pumps ?

Seems strange that the fuel pumps would prime, electrics work and then engine crank over even though the kill switch is armed.

I would assume that a kill switch would not allow any power to the ignition and starter motor (ie non-startup) in order to prevent this situation?

 

Is your F40 a 1992 or a different year? Maybe the kill switch was added near the end of production?

Can you post a photo?

 

I would imagine it was installed at the request of the first owner, the early 90s were one of the worst periods for car thefts in the UK/ Europe and normal alarms were easy to bypass back then. I have always had such a switch hidden inside all my nice cars, killing the supply to the pumps.

An F40 is not exactly difficult to get into and hotwire, a basic switch like this confuses most thieves, mine certainly did on one car I owned in 1991, they got past all the installed security and a £2 switch saved my car from vanishing.

 

Interesting. Obviously effective!
