hi, Ive just joined up this evening and im hoping to get a bit of help with my 1990 xr3i. The problem is with starting, unless i press the throttle all the way down it wont start. ive only just got the car on the road a week ago and had been fine, it started getting a bit jumpy and not pulling to well so ive changed the leads and put new plugs (gapped to 1mm) thinking this would fix it. it runs a bit better but still the same problem. i Tried taking air filter out but no difference when i took the fuel return pipe of the regulator the full pumps out well when its priming up but only a small trickle when turning over.

Any help would be much appreciated, Paul.

Have you tried changing the fuel filter. Its supposed to be done every 25k miles but probably not been done in 10 years if you haven't changed it.
