Fuel pump not priming.

[threespins]

Good morning gents, my 1998 400 has been stood for about a month and now won't start. The fuel pump is not priming although immobiliser seems to be going through its sequence. I have checked fuel pump and connections are clean and tight but no voltage present when fob is pressed. Giving the pump a tap has made no difference either. I have disconnected the battery to see if a reset would do anything but no joy with that either. The relay connections are also clean and tight. I am now stuck so would appreciate what to do next. Many thanks.

Many thanks, trouble is I'm as deaf as a post so would not hear the relays. Anyway swopped the two relays round and although it took about four attempts it eventually started. So any ideas, relay doesn't like being stood in a cold garage?!

Yes they are the metal ones with a red stripe. Well Chimp, what can I say great answer, never seen the operation wrote down like that in plain English and easy to understand. Thanks, that I will save in my history file. So assuming there is a relay problem within the immobiliser, what is the answer? Can it be repaired or replaced or is it a case of fitting a different one and ripping the Metec out.

Pump connections are good, clean and tight. Will check the fuse next and change the old relays as a matter of course.

I figure like Oldred V8S that it is a sticking relay, just seems to happen when car has been standing in winter. got two new relays coming tomorrow so will prove it one way or the other.

Hi Chimpongas, I agree with everything you say. I do have an engineering background and have several multimeters. I just thought that as the relays were 16 years old and playing about with them got the car going then it would be prudent to change them for what little money they cost. They are now changed so I will report back after giving it some time without further trouble.

That made me laugh Chimp, just about sums up the phrase "they all do that Sir"
Great information though, learning more each day from you.
How does the alarm fit into all this, is it totally separate and just to do with locking the car?
