Fuel pump - fuse or relay position?
Afternoon all,
Is there a fuse for the fuel pump? If not, where's the relay for it exactly? Story so far:
Car was running fine all day (UK MY98); parked up, then it wouldn't restart when I went to use it a few hours later. It just turned over & over with no sign of firing.
Cleaned the cam & crank sensors, then checked for fuel at the filter with the ignition on - nothing. No noise from the fuel pump, so put in the new Walbro I had on the shelf. Still no priming noise or fuel flow - aagh!
Multimeter shows no power going to the pump with the ignition on - am I missing something, because I don't think there's a fuse for the pump?
I guess it could be the relay (which is presumably somewhere behind the dash?) - apart from the new pump, the fuel system's standard, as is the ECU.
As always, all helpful pointers appreciated!
Cheers,
Steve

if it's got a sigma alarm on it it's probably the alarm ecu i've changed a few now for not powering the fuel pump, no pattern to them sometimes they work ok then they don't

Scoobyboy - it has got a Sigma alarm.
I tried putting it into Valet mode & the car actually "coughed" a couple of times on cranking, as though it wanted to start, but I checked the fuel at the filter - still no flow.
Swapped over the fuel pump relays onto my mate's car (cheers Scott) - his car fires fine, so my relays are ok.
Time for an auto electrician/RAC I guess. Being colour-blind, I don't mess with electrics!
