My U13 lx started playing up in the heat last week when my son was driving home from work. Firstly it just lost power and then started to cough and splutter at idle. If you let it sit for 10 mins it was fine for a few K's then would do it again. He thought it may have been low on fuel so filled up and it got home. We had fitted an after market fuel pump about 2 months ago and thought maybe the pickup had moved in the tank and wasn't picking up fuel near the bottom of the tank. Next day did same thing, losing power rough idle then just stopped. This time wouldn't start at all. Won't even turn over. All dash lights fine, battery fine alternator charging fine, RACV thought maybe starter is cactus. We push started it in the cool and drove it home about 45 k's no problems at all, but it won't start with the key. Could both problems be starter related? Maybe drawing to much power? When I turn the key the clock on the dash and the radio stop but the dash lights don't even dim. Could it be the ignition switch? any clues? Anybody had anything similar?
