Let me get this right - a mobile mechanic came out, tried EasyStart (and it still wouldn't) and diagnosed the fuel pump? Without checking the cam timing?

No wonder he's a mobile mechanic, moving targets are harder to hit!

It is all a bit vague as if he doesn't know what he is doing . All fuel injection systems are similar . Generally the engine will run if the tank pump is faulty and there is half a tank or more of fuel , but it will make the main pump noisy as air bubbles are drawn through .

At the beginning that mechanis as quoted makes no sense. If it won't start with easy start that might indicate that it is not a fuel problem? The evidence might be right there for you. And Clan has explained re the usual thing re fuel pumps.

How many times has that mechanic attended and how much have you paid them? There are good mobile mechanics/diagnosticians. And good ones in garages. I really think you actually need to find a good garage.

I am "not convinced" re meths when a car actually just won't start.

Anyway, tell me please. Was the car ever starting and running OK and if so when? Now, when did starting problems start and did they arise as poor starting or not starting? .... &c. &c. Tell the story in nice simple terms from the beginning. Please mention anything and everything that has happened or been done to the car during that period of time.

And. PLEASE. Answer the actual questions that the "expert" people ask you.

As always, good luck.

And for example. What EXACTLY happens when you try to start the engne, with or without Easy Start?

And for example have the plugs or plug leads been removed changed disconnected? Did the leads go back correctly?

Ahem. I walked away from my brother in law's VW horizontally opposed twin when he pulled off all the plug leads and did not know which had been connected to which plug. I find it difficult to be patient with that person generally....and I was tired. He had escalated a broken fan belt in to a disaaarster...

yes the car has been running great until the back box on the exhaust bloo open and coursed a small back fire as ive already said if you read my reply.and was idling very bad after that engine very unstable .then it just stopped from starting all together.so i changed the plugs leads rotor arm dizzy fuel relay and fuel pump.today ive checked for spark on all the plugs and they are ok.

More than likely an ignition timing issue , I would change the crank position sensor ..

and on starting the key its just turning over without firing.he took the air cleaner pip of and sprayed easy start down the pip while i was turning the key and it was almost firing up but not starting and just said there is no fuel getting to the engine

90% of all fuel problems are ignitiom related.
I got most of informations of your car together.
Still : has the engine a spark at the central lead of the dizzy?
If yes, does it have spark on all 4 spark plugs?

Did you swap the firing order?

Still 2: Your car isn't with a CSP

Still 3: Do you own or have access to a multimeter? Do you know how to use it?

I can't help you otherwise.

We have to go step by step.

There is no whish free anymore

Good luck, Kay

Doesn't have it. Either duff fuel or cam timing is out.

[atco]

this car dont have a cps.ive checked all plugs today and they all have good spark also checked the timing marks on the belts and they all match up also the leads are in the right order and even if they were not it would still turn over.no multi meter.

DO NOT USE THE BELT TIMING MARKS TO CHECK IT'S TIMED CORRECTLY!!!!!

You don't know if it was fitted correctly in the first place andbecause the distance between the marks isn't even, there will only come a once in a lifetime occasion when they are in perfect alignment again.

Use the pointers on the pulleys and timing covers to check the timing. As far as i'm concerned, you either have condensation in the fuel (the meths will sort this after a few minutes of cranking) or the cam and hence ignition timing is out - you MUST check the pointers on the pulleys and timing covers and "near enough" ISN'T good enough!
