A friend has a 800cc jcl or jlc what ever it is.We rode ,he washed it then it wouldnt stast.The dealer told him to change the ignition.He did that didnt work,if he puts power to fule pump it fires.The buggy is new 20-30 miles,any ideas.

I dont dont know much about those buggys but I would check to see if there is a fuse to the fuel pump.Let us know the out come!

The fuel pump power is controlled by the key switch. Perhaps water or mud got into the contacts?

Ill pass that on.

The fuel pump may also have a relay if it is EFI the relay will be by the ECU.

I thought he said if he put power to fulr pump it would fire.

He did...

If you have an electrical diagram, that will help.
However you can do most of the troubleshooting without one for now.

You indicate that if he puts power to the fuel pump it will start. Well, trace the wires to the fuel pump back to the next device. Take the wire off there and apply the power to that end of the wire. See if it still starts. If it doesn't it's in that wire/connection between that point and the fuel pump.

If it does, then the problem is from that point to the ignition You'll need the wiring diagram if the next item in the wiring harness is the ECU.

These have a Suzuki engine in them , right?


With power available and the key switch in the on and start positions you may be able to track it down taking voltage readings on each of the wires going into and out of the ECU.

It may take some time to narrow this down. If the cost of an ECU isn't too much I may just purchase a new one to assist with the troubleshooting.

I can't believe the dealer had you purchae a new ignition with that few miles on it.. It's still under warranty, right?

I would have thought that they would make the buggy more durable than this.

My buggy has a red kill switch on the dash that cuts power to the fuel pump if your unit has it did it get turned off by mistake?
