Help Relay problem
fishachuck - 8/5/15 at 10:56 AM

Hi

Got a problem with a Siemens Relay part number 90459642 does anyone know where i could get 1 for sunday i'm supposed to be going to cars in the park at Newby Hall but the car won't start without it, there's a few on ebay but won't be here in time, absolutely no good with wiring so no idea if there's anyway to bypass this, any ideas/suggestions would be gratefully recieved...

thanks Pete

Looks like a std 30A relay to me. Halfords, maplins etc should all keep them.

However, the pics I found make it look like one terminal is extra big, but a normal relay may well still fit, difficult to tell.

Apparently it's a Saab / GM fuel pump relay. Any decent autofactors should be able to sell you one.....

Just rung round all motor factors in York where I am but they said it's obsolete now and they don't do them anymore,

Try these people, they may be able to ship on an overnight service?

By the pin arrangement it looks like a change over relay sometimes fuel pump relays have built in resistor or diode.

Landrover Bosch fuel pump relay http://www.ebay.co.uk/itm/Bosch-fuel-pump-relay-0332-014-112-from-Powerspark-/110882274806?pt=LH_DefaultDomain_3&fits=Car+Make%3ARover&hash=it em19d1193df6

I can't seem to find this, is it something I would definitely need/have..? I turn ignition everything lights up but turn to start it and nothing just dead, checked battery and all wiring to starter everything seems to be fine that's what made me think it was the relay, but like I said I no absolutely nothing about wiring... Also if I bump it off it runs absolutely fine....!!

Clutch Switch?
Key Barrel switch?
Broken connection/Cable?
Bad earth?
Is the relay energizing?
if not maybe wiring/Starting switch issue.
Hot wire the MF...

So the car runs fine, just won't start?

How about starter solenoid?



The inertia switch is fitted inline (usually just to the fuel pump) so it shuts off after a heavy impact, obvious reasons. With an electric pump it should have one. Really, if it hasn't, I would be putting one in.

Yeh car runs great once started, can I test the solenoid.? Although it's only a few months old.

I'll check again for inertia switch maybe it's near the pump it's self..

Perhaps I have the wrong end of the stick. .. but if it runs ok... it's none of the inertia / fuel switches etc. it can only be a start problem. I would take a stick and give the starter a sharp tap to ensure it's not a stuck bendix. If that doesn't work, then a thick 12v feed taken direct to the solonoid will check that. If that works then follow back the wiring from the key switch...

Thanks Howard, Yeh all runs great if I bump it off so I'll try your suggestion tonite when I get home, thanks again....

Yeh starter solenoid was at fault all along by the looks of it, give it a clout and she fired up straight away what a plonker...lol
Thanks for all the help guys much appreciated....!!
