Efi/ignition

[gevandam]

Have a 2005 FSE450, Was running fine and lost power, could not restart, no spark. Battery was charged and still not starting, any Ideas?

is there a fuse panel? may have a blown fuse?

Does the fuel pump run for a short burst when turing on ignition? (does the headlight come on?) If not, there may be a solenoid problem. The same solenoid feed the ignition coil and the fuel pump. Solenoids are located behind the right side panel. I think the fuses are there too.

1. check fuses
2. If/when fuses are ok and pump still not running, switch the two solenoids.

if fuel pump is running and still no spark, disconnect the ignition coil connector and use a voltage meter and check that 12V is present at connector pin 1.

Get a replacement coil(kinda expensive, tho).

Check all connectors for bad connections, oxidation.

Use the electric schematic from the manual as an aid in troubleshooting. Be patient and thorough.

Keep us posted on progress.

Possibly the relay. Take off the right side cover and switch places of the 2 there.

I have had the same problem.1) the relays in the airbox 2) fuses in air box area and the headlight area. 3) the on off key, the wire breaks under the silicon, I use a togle switch now. 4) the fuel injector. Try this order also check for any broken wires behind the light. All the info before this looks good. Good luck. Tom
