Help - Fuel and spark but will not start!
Discussion
Drove fine a few days ago, but now will not start.
Engine turns over fine, there is a spark and the fuel pump primes.
It had a service last month, plus a new battery, a bosch coil and new plugs.
I removed the plugs today to dry out, will refit and try again tommorrow.
Advice appreciated

So was it just flooded?
If it was and if does it again a quick get you going fix is to pull the metal relay on the loom in the footwell. The relay controls the fuel pump so when unplugged you wont hear the pump prime.
Unplug it and crank the engine till it fires and then plug it back in again.
There are two metal relays down there but you will know if you have pulled the wrong one when you switch the ignition on and you hear the pump buzz.

It lives!
Thanks for the reply.
It was the rotor arm. Put the old one back in and it fired and ran 1st time.
I replaced the rotor arm a few months back. It arrived in a Lucas box but had no branding or codes on the arm.
I recommend the plug testers from Halfords they were really good, I could see I had an intermittent spark - Good spark, weak spark, good spark etc.
I have a new Bosch coil so I knew that was good. Tried a different ignition module, no change. I thought it was something simple and it was.
Just need to track a genuine arm down now - does anyone know it there are any suppliers near Bristol?

Exactly the same thing happened to me. I was trying to cure a miss fire and replaced the entire ignition system trying to cure it.
I took the car to Castle Race Engines in the end and Jamie asked me if I had replaced the arm. Once I told him what id done he changed it for a 2nd hand one and problem cured.
