Found the fault, a simple fuse. I first replaced the fuse but when I found the bad relay I switched it out. When I switched on the Batt, with the new relay it blew the 30A fuse because the pump was bad. Switched out the pump and relay but not the fuse. Checked it and sure as the sun shines the new fuse was blown. Bought another new fuse and put in the grey relay and Wheeeennning! Just a little trouble shooting and down the road. Much thanks to the forum for saving me a great deal of money. The shifts are so clean and it has never been better. Even with having two extra relays and some extra fuses this job was only $400. The pride of getting your Maserati badge on your tool box...priceless. Thanks again you guys for making this a done deal, here is a link to the pump I got off ebay. http://www.ebay.com/itm/161650977391?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT

Good news, that is rewarding.

I like the cheap fixes!

Enjoy, looking forward to getting mine out in 3 weeks (out the country until then)

I've changed every fuse on the car for those illuminating glow fuses, including those maxi ones too.
Should save time incase of an electrical problem.

Sorry to barge in but I am hoping you can help me out with the dreaded F1 pump problem
I have a 4200 cc which a few months ago would not engage a gear after reversing off of the drive. We managed to get the car on to the drive but she would not start an I has the cc warning light on. I left it a day, went to see if anything had changed and hey presto she started. Three months later the cc light is on and she won't start. I can hear the relay click when the door is opened or ignition is on. Is this a pump failure or something more sinister?
Any advice would be much appreciated

Could be either. Check the fuse first. If that's blown, you'll get the relay (I think) but no pump. If that brings things back, then you'll need to do some checking on how frequently your pump primes and so on. Other possibilities are failed relay, failed motor and then things start getting a bit spendy....

Given your previous experience (can you recall if the pump was priming then) I'd be looking at the relay seriously as well. But if that has failed it will still be worth checking the pump

Welcome to the forum BTW :)

Hi
Thanks for the welcome. The relay is brand new and all the fuses are all ok. The pump used to prime but no more. Maybe if there was enough pressure stored within the pump it would have enough to fire up. I am not to worried about replacing the pump as it seems relatively easy to do. What I am worried about is it not being the pump and being the gearbox.

That's not how the pump works. It's just an electric motor.

So relay is new, fuse is good. Have you tested for 12v on the pump? That would be my next step just to confirm that the motor is getting power. If you're getting 12v then you need to replace the pump *or* the motor. Motor is easier, but if your pump *has* failed, then the motor may well burn out (again).

For me i'd look at just swapping the motor. Sure I read it was possible somewhere:

Sorry for being thick but is the motor part of the pump or separate? As the Alfa pump is about £800 cheaper than the Maserati model I will just order one so I can cover the bases. I am no mechanic but I can undo a nut. If the pump is not getting power then I am buggered, I would not know where to start except with a BFH!!

I'm pretty sure the pump can be separated from the motor. I think Craig Waterman did it that way, and it saves messing around with fluid and so on. I suspect buying the Alfa pump is probably the cheapest way to get a motor as well, although I guess you might be able to find an equivalent.

If it's not getting power then you need to get back to basics. Trace the power back. Plenty of Indies can assist with that kind of stuff, or if you trust us kack-handed amateurs, we'd probably be able to make a fair fist of sorting it out. As long as it's not an ECU / TCU fault, which is where you're going to need some serious diagnostic kit.

I have a spare used pump you could try. Can be picked up near Bristol from Thursday evening.

Cheers guys, new pump arrived today. Alfa alternative brand new for £190. I am fitting it tomorrow, bit worried that the pump is not getting power, if that's the case then it will be a trip to the garage. I have always wanted a 4200, I love the lines, the engine and the noise, especially with Larini cats and custom built back boxes. Problem is the amount it has cost, new cats, new clutch, new lambda sensors, welding to the manifold to get rid of the infamous knock, new radiator, new ps radiator. Still if didn't have the car I would only waste it on something else!!

There all Bargains when you think what the first owners pay for them.
My old Ferrari 456 190,000 pounds new was unreal when I got it with full history for 25,000 in 2012 and now double still cheap compared to being first on the Log Book.

Just spent the day changing the pump. All seems to be working well. It please be aware that this job is not as easy as it looks. The hardest part was getting the old pump off and dealing with the nuts that hold the heat shield on as these shear very easily. I also had the benefit of a full workshop ramp. If anyone needs any help with this please get in touch. My email is steve@frontfive.co.uk
