V8 Running problems

[spike2450]

Hi all
I have a 1998 5.0l v8 with thunderbolt 5 ignition, It starts and runs fine for about 10 to 15 seconds and then cuts out, it does the same whatever the throttle/revs are. It idles at 600 rpm. It doesn't restart straight away, i was thinking fuel and therfore changed the fuel sepaerating filter but she still consistently dies. Any help would be great.

Most likely ignition module.

I have a complete scrap engine in my workshop if your interested, I will ring the owner and ask him what he wants to do with it.

Have you checked the oil pressure switch that goes to the fuel pump ?
You have an a oil pressure sender that goes to the guage on the dash, but also you a seperate switch that goes to the fuel pump, idea being that it wont pump fuel if the oil pressure is low, it will only give you 15-20 seconds of running which seems to be what you are getting. I have heard its a common problem, easy to test just jump the wires on the switch and see if it cures the problem.

Typical marine engineer turns up and it doesn't cut out, ( midas touch). It seems to be runing rich i'll post again the outcome.

If it is a carburetor model check the choke operation.

Hi all
Problem sorted, i tried what neil said above and bridged the wires at the Oil pressure switch that leads to the fuel pump and she is now purring like a kitten.
