Re: no power in fuel pump;no power ignition coil;no power...
Check the battery to see if its not bad. if it isn't bad then the only thing i can think of is there is usually a main fuse for the battery. On my car it is on the wire coming from the battery. some cars it might either be in the fuse box under the dash or in the box under the hood.

This relay is in the power distribution box. It's purpose is to link the computer with the ignition circuit (the coils) and the fuel pump circuit. When the ASD relay shuts off (by turning the engine off) power is cut to the coils, and in most cases to the fuel pump.
It could be just about anything was it driven normal before it died or was it acting up . make sure that the gas is actually getting to the engine if it is i would maybe change the spark plugs. then the computer again . but may start to get costly by guessing you may want to bring it in for test..
There are some possibilities which you
will have to check in this case:-- 1) First of all check the power and
voltage to the battery.with meter it will show exact 12 volt if the
battery is charged.if the voltage is less get the battery charged at local auto
repair shop.if the battery is internally drained and not getting charged then
its time to replace the battery. 2) When you crank the caravan do you see
spark coming at the spark plug? if no then its time to check the spark plugs
and coil pack.if the spark plugs are not worn out and looks new then its time
to check coil pack.the spark plugs gets power to spark from coil pack. 3) The other thing to check in this case
is the starter solenoid of the car.if the battery is charged and you start the
caravan then it gives power to the starter to start the caravan.but if starter is
faulty or not connected properly then car will not start. 4) The other thing to check in this case
is fuel in the caravan.if there is fuel in the caravan then check the blockages
in the fuel pump if the fuel pump looks proper then check the fuel filter above
the fuel pump. 5) If all the above possibilities
mentioned above checked out OK/perfect then its a electrical issue and
the wiring's in the Caravan needs to be checked.the caravan gets
power from the battery to get started.so the wires from battery needs to be
checked one by one. Thanks. keep updated for any more
query.you can rate this solution and show your appreciation.
Start with fuel system. Listen for fuel pump humm at fuel tank No humm check wiring to pump for power. Then check for spark at plugs and wires. Remove wire from coil and hold near engine and see arch when you crank. No arch. Replace ignition Modular inside distributor cap or cap or rotor
GO BUY A CHEAP CAN OF STARTING FLUID AT THE STORE AND SPRAY A LITTLE IN THE ENGINE AIR INTAKE , AND TRY IT. IF THE ENGINE STARTS, IT IS ETHER A BAD FUEL PUMP IN THE GAS TANK, OR A STOPPED-UP FUEL FILTER UNDER THE CAR.
