    hi! the car as described above is cranking and would not start, i could not hear the pump priming. the car already has the orange clip on the fuel filter. i have checked fuses and swapped relays but still no joy.

    Is that the V8 you are talking about, which you bought over a year ago? If so, are you trying to start on year-old+ fuel, it may have become waxy and have caused fuel feed blockage(s). Risky using very old fuel anyway. Injectors can become blocked or, if it does start, even self-destruct causing untold problems ('Harrygsi' managed to kill his engine by hydrolocking probably because of a failed injector "hose-piping").

    Anyway since you are now an owner, you can go 'green' as a full member, and get lots more handy information here; just get on to Tim for a questionnaire.

    • Spark - faulty ignition circuit

    I have checked the fuel filter, swapped the relay and fuses, still nothing.

    Do you have fuel pressure? Do you have a spark?

    Have you done anything to the car since it last started?

    I have not done anything to the car. There is no fuel pressure as the pump is not priming.

    Do you have 12v at the pump?

    If you do then you probably need a pump if not it could be the module in the boot, a relay, fuse or the the ECU is not sending a signal for some reason. I know on som GM vehicles a faulty CPS can cause this.

    I think the first thing you need to do is get your questionnaire back to Tim to get full membership, you will then have access to a lot more information to help you try and solve your problem.

    You need to apply a bit of logic to your problem before jumping to conclusions. If the car is cranking but not firing you are obviously not getting any fuel to the cylinders but it's probably worth checking that you are getting a spark at the plugs first anyway. Once you have checked that you are getting a spark then it must be the fuel supply. Start at the pump, you say you can't hear the pump priming, that's pretty subjective, check that the pump is getting an electrical supply and if it is then is it ouputting fuel at the correct pressure? If everything up to this point is working as it should then work through the rest of the system to check where the fault lies, gradually narrowing down the options.

    Hope this helps.
