Peugeot 307 not starting ignition fuse keeps blowing!

Does the fuse blow when you turn the ignition on, or does it blow when you actually start to crank the engine over?

It just blow's when I turned the ignition on.

Well that rules out the starter solenoid side, but still leaves the ecu, fuel injection pump, even the fusebox and ignition switch.

Thanks kindly for your concern.

Are you able to help with the original question?

Provide me with a wiring diagram or furnish me with the details of what devices are on the affected circuit, and I'll quite happily point you in the right direction.

if it is the fuse for the ignition circuit, my money would be on a faulty ignition coil pack.

There's a full set of wiring diagrams for the 307 here.. albeit badly laid out.. you could do with an old-fashioned overview of the whole ignition system.

Not sure why you're asking on this forum.. it's interesting for others to read, but probably won't get your car fixed!

you could do with a multimeter, and test for continuity where it shouldn't be.. you've got a bit of job since it's an intermittent fault.. the fuse has never blown while you've been driving along? it only blows when you go to start it? or did the fuse actually blow when you turned off the engine? IYSWIM.

EDIT:

Are you sure that it is the ignition fuse that is blowing?

According to the table linked below, the fuse for the ignition circuit is 30A, not 20A.

There should be a diagram on the back of the fusebox cover or nearby to the fusebox. That should tell you what each fuse is for. It seems that each fuse in the Peugeot should be numbered using the scheme F1, F2, F3 etc.. What is the number of the fuse that keeps blowing?

You can't rely on the rating of an existing fuse to be correct. The !!!!!! who sold you the car might have put a 20A fuse when a 10A fuse was intended by the manufacturer!

See what you think from here.. http://www.peugeotlogic.com/fuses/fuses307/307fuse1.htm

Thank you I was sh!tting myself on the way home for this exact reason, thankfully I didn't have that far to go.

Only problem is that:

a) it doesn't matter how far you have to travel
b) It may be a constant live circuit that carries current even when you've got the ignition turned off so you could walk away from the car after the journey and it still set alight. At least one of the wires going to the back of the ignition switch is a 20A rated one and is constantly live....

OH! sorry I mistook this section of MSE for help. No worries I will take it to the garage.

Thanks
