ok will look out for a pressure kit. i think ive found a few on ebay that go to 100psi, but i think theyr only for carbs. am sure therl be some around though. motor spare shops dont seem to do them...

was reading this on another site...

Diagnosis:

Check for a spark using a spark plug wire and a paperclip near ground. If you have a spark, then your fuel injection system is a candidate for further investigation. If not, then your ignition system is at fault.

I have a spark so its definlty not this.

Next, you could replace (or use a spare) the fuel pump relay. Normally, when you switch on the ignition, but just before you actually crank it over, you should hear the fuel pump working, (a faint whine) then it stops (i.e. it is priming the system to pressure) If you hear nothing at all, then the relay could be bad (it is a green bastard stuck in the row of relays (usually top left as you look at it) behind the ash tray. You should remove the little shelf panel to get at it.

Relay is working fine!

Another thing you can do is undo slightly one of the unions in the fuel distributor, using a 12 (or 13mm) mm ring spanner. Normally, undoing one of these, there will be a spurt of fuel. If there is nothing, you have no fuel pressure.

Here i have no fuel. AT ALL !


So far it could be the relay or the main pump. You could buy a new relay, slot it in and the car should go. If not, then it is your main fuel pump (or pump wiring, but that is less likely, as the connections to the pump are very solid and durable) You could disconnect the pump wires (you can do this without removing it completely) and get someone to crank while you test voltage across the connectors.

So these guys are pretty much certain its the fuel pump...

what should the readings be on the fuel pump while cranking and while just priming.? worth a test.
