Gday guys,newbie here
Ive recently got an EL Wags off my parents.Cars not bad for 18 years old
So...theres been 1 or 2 times it has troubles firing.It cranks fine but wont turn over.
I had NRMA come out,jump the battery after getting a little over zealous trying to make it fire.As soon as he jumped it,it sprung into life
After further investigation,i red on here about the CRT LP fuse.The fuse is fine,not blown but obviously if i take it out,it has the same symptoms as when i had to call the bloody mechanics.The car doesnt run an interior light globe either.My question is,would it just be a simple fuse issue with the car not starting every now and then and and after the car gets jumped,or should i investigate further?
Cheers

Next time it happens give the dash near your left knee (beside the steering column) a whack while cranking. Sounds like a bcm issue

Ecu controls the pump im fairly sure. Bcm controls all your body electrics and smartlock. Alot of e series you need to thump the dash. It can be a bcm issue or wiring into the bcm
