Help car won't run/start

Well most of yu will know that car is off the road again
Driving car all going well until it just dies as if lack of fuel
So have changed fuel pump but still won't start ! And can't hear fuel pump
Prime at all !
all fuses are fine, sounds like alarm/immobiliser deactivates
It's turning over just seems as if no spark

What's the next thing to check

Cheers guys [right]

Hey Shaun,
Why not run a fused live to your fuel pump and check to see that it runs as you will soon hear it whirring away.
If it does then try to start the car - if it does start then you have a break in the wire somewhere and then you could just run an ignition feed straight to the pump to keep you going.

If that doesn't work you may have a faulty crank/cam sensor.

what year

whats your location ? cud pop over if not to far and check the electrics tomorrow if thats any help

Cheers for today craig most appreciated

Is it sorted now then mate what was the problem ?

Well found a water damaged relay and fuel pump relay not
Engaging either so tried running bridged wires and still no
Joy ?
Next gonna try replacing relays and cam nd crank sensors now
And then take it from there !

Have u tried to see if you have a feed at the pump if not try running a live from btry to pump and see if it pumps (or a neg and a pos feed of btry if that doesn't work could be a dodgy earth ?)

If the above works at least it will tell u your pumps ok and its your wiring which you will have to trace !

Pump is working and still not firing !

sounds like a immobilisor problem to me.

Well Craig
Tries tapping into wire either side of the immobiliser
Tapped into and it's disabling and allowing feed thru

The alarm is a cat1 so only disabling the fuel pump. Fuel pump relay getting power to the coil from the ECU but not pulling in. So i bypassed the relay. Pump running ok. But still wont fire. The alarm relays seem to be working can here them click in and out ,and once the fuel relay had been bypassed and the immobilizer was on the pump didn't run until you turned the alarm off.

If i didn't have to go to work Muzz i would have took the alarm out altogether as you said you were getting a new one fitted to eliminate the alarm altogether.

Let me know what happens when you get the new relays. Free most nights to pop over if you need a hand only 10mins up the road

Craig

Ur a star mate thanks alot
I was trying to say that lol

ok guys got the car started and now need to know wot the symbol is on the left next to oil on dash cluster



although the car starts its still running like shit and i have to beat that light from coming on otherwise doesnt start ?

it's the cat on fire lamp. As far as i am aware this light won't cause any running problems. it just goes to a temp sensor in the cat

did it start as soon as you put the relays in mate?

Nah had to disconect couple of wires that we must have been trying
Under the dash m8

But gonna have a good luck over on tues nite

I believe cat 1 alarms have two immbiliser circuits, some super duper alarms have 3 circuits.

What alarm is fitted?

Autowatch 160rli

It only has the 1 circuit ?

wen u say it started ?

was it really lumpy and unwilling t rev etc ?

if so could be faulty water temp sensor

you checked for any fault codes ??
