After or during rain with the water on the road the car will have an engine shutter and slows right down and then cuts out, it does not want to start and drive until a about 12 hours latter.

This sounds electrical in nature.have you inspected underneath and inside engine bay for trailing or bare or cracked cables.water is ingressing onto part of the electric system.could be anything from the ignition such as ht leads ....cooling such as electric fan.... Alternator....battery.check every where for loose ...frayed or bare wiring.you may have lost a splash tray that was removed during servicing or water may even be finding its way through front grill straight onto part of ignition system.lastly the ecu will record most events and log them as error codes which can be read at a local garage and reveal what may really be going on.unfortunaely some garages charge a fee whereas you might find a local one who will not.

The first thing to do is to have the fault codes read. If you comment with the codes found we may be able to point you in the right direction as to how to fix. Do this first before you spend heaps on all the wrong things.

Common problems
1. fuel filter clog and fuel pump stop working
2. Crankshaft sensor (spark is cut during high demand)
3. Air filter clog (not enough air during high rpm
hope it helps

Just water getting on your belts . Normal.

If the check engine light is on have it scanned at Auto Zone to pin point the problem. If the check engine came on then went off it stored the code in the computer you can still pull it up.

I HAD THE SAME PROBLEM BUT WITH AN ASTRO VAN. THE PROBLEM WAS WATER WAS GETTING INTO THE FUEL PUMP CONNECTOR UNDERNEATH THE VAN, NEXT TO THE FUEL TANK.THIS WAS CAUSING A SHORT, NOT BAD ENOUGH TO BLOW THE FUSE, BUT ENOUGH TO CAUSE THE PUMP TO SHUT DOWN. BEST WAY TO DUPLICATE THE PROBLEM IS TO FIND THE CONNECTOR AND SPRAY IT WITH WATER WHILE THE VAN IS RUNNING. ALSO DO A WIGGLE TEST, THIS IS DONE BY GRABBING THE HARNESS TO THE PUMP AND MOVING IT AROUND, IF YOU HAVE A LOOSE CONNECTOR OR A BAD WIRE THE VAN SHOULD SHUT OFF.

If you lift your hood, check the wires that are for your windshield wiper fluid, I had the same problem and because the wires were being pressed against the molding water was able to drop down onto the engine. When ever it rains really hard felt like the truck was going to cut off. But when the sun was out my baby would pur like a kitten.

check the wires to the fuel pump if they have rubbed against something and the insulation wore through hitting bumps or rain could cause it to short and kick the relay and resets again and will start

sensor problem ,could be the crank sensor accepting water seepage was it raining when car cut out,or maybe evan connectors on the coil pack,clean all visable connectors and use some vasaline on them then warm engine up and spray with hose just see what happens ,other than that call out your friendly mobile mechanic or be prepared to lay the golden egg at the dealers

I have an 85 fj60 that keeps cutting out. the catalytic converter has been removed, the fuel filter is new. As soon as the engine is relatively warm, the engine cuts out when accelerated..... any suggestions?
