Just changed the fuel pump, and its not even priming , on the old pump only the one wire was connected so I did the same on the new one, what is the keyfob shaped thing attached to one of the clip/bracket that holds the pump inplace ,,,

Thanks yes it does, i connected the other wire and now is priming but still no start, I had to empty the fuel tanks before changing the pump and now its turning over but not firing,,,

Do you have a picture?
Have you checked for fuel and spark at the plug?

[gwentman]

check for spark first,take middle lead off distribitor, and hold close to engine, get someone to turn engine over, if spark, change rotor arm and cap, I just did this and my chim is up and running

[kennybgr8]

here is a pic all it says on it is MTA ITALY 2.2mf 110v 100c its about 50mm long




I will get working on the car shortly, everytime I turn ignition on the alarm now sounds so annoying for Neigbours and me even accepting the alarm it sounds seconds again after that ,,,

[kennybgr8]

Thanks Ray will try that also, it was never a problem before I changed the pump,,,

Hi Kenny,

That "gizmo" does appear to be a suppressor - I assume that TVR fitted one to prevent radio reception interference.

There's a schrader valve (a tyre valve) on the fuel rail ... if you take the cap off that and (holding a cloth round it to catch any spillage) just briefly press the valve bit then does fuel spurt out? (If it does then it should be under a hell of a lot of pressure.) That'll check that you're getting fuel as far as the fuel rail.

Cheers

Phil

Thats everything connected up for a second time I will now try locate the valve, should it be primed before the fuel comes out or will it spurt fuel with out ignition being on,,,


Kenny

[kennybgr8]

Still not firing there is no fuel coming out of the schrader valve, I previously mentioned there was only one wire connected to the pump on the old one, I connected both then it appeared to prime, is it possible that the wires are the wrong way round, I can easily change them but if its wrong will it fry the pump,,,

[kennybgr8]

Oh and there is plenty spark from the distributer, but no smell of fuel grrrrr,

[kennybgr8]

To recap, when I took the old pump off I had to empty the tank into buckets reconnected the fuel hoses is it possible there is air in the system blocking the flow to the plugs, Im going spare its a lovely day here and was going to go out a run ,,,,,,,,,,,,,,,,,,,,,
