Right bit of an update....

Been on the phone to colin at AVA and he reckons the same. check the power to the fuel pump then check the relay.

Now ive been working on both cars today and i know this sounds funny but when i take out the small plastic shelf on the right hand side of the driver under the dash to get to the fuel relay(just above the drivers speaker) the car starts no problem. but when i put the shelf back in it wont prime

I know it sounds rediculous but can i be disturbing anything in there?

tearing my hair because i replace the starter in my fieats and the new one has the same problem as the old one and now ive changed the sump and the crankshaft seal leaks

Not a good day for me and mechanics
