Any help much appreciated!

1995, Fiesta with a 1.6 zetec

Started my car up, ran for about 2 seconds and then it cut out

Tried again and did the same thing! (about 4 times)

Looked at the petrol gauge and its 1/4 of a tank under the red, but I had at least 1/4 of a tank in there. It was used earlier this morning with no problem.

Can here the F pump priming and its turning off about a second after the IGN its cut.

Dont think its an ignition problem as its running perfect for the 2 seconds it runs.

Checked inertia switch too and it was good.

Any ideas???

Thankyou
