I really hope someone can shed some light on this as its driving me round the bend!
97 silver 6 developed an Intermittent starting issue a few weeks ago, seems to roll the dice as to whether it will start or not? looked over it with a technician friend and confirmed spark but no fuel. We have replaced the fuel pump to no avail and moved on to replacing the relay but still no luck, the problem persists.
As such we think we can rule out things like immo(has spark), crank sensor (has spark) now fuel pump and relay is this correct?
In faulted state, at first fail, it will start badly, splutter and die immedietley, as if not enough fuel is being delivered and its failing to start on the dribbles in the line, then will just crank but not start until it 'decides' to go again. When it runs it runs perfectly. I have also noticed a new quirk which is the engine temp light now swings quickly up and down a couple of times whereas before, at the second ignition position it would illuminate, needle would rise up and stay for a few seconds then come back down, is this related?
It has spent the last few days in a garage and they couldn't get it to fault, started every time on the button only to have issues an hour after I picked it up with newly sealed fuel pump and new relay.
I'm desperate to get to the bottom of this as the anxiety of not knowing if it will start when it's time to go to work or come home is unbearable, any info or help would be massivley appreciated.
Many thanks,
Hatch
