My GT JTDM is current stuck at the bottom of a long hill after I failed to get it to bump start
I have managed to bump it a couple of time but not today.
Anyhow, the need for bumping it is coz the starter appears not to be working - but I'm open to ideas on what else I should check before jumping to that conclusion.
Recent history - Car had been getting sluggish to start, especially since the colder weather started, put new glow plugs in (mileage ~120k), seemed to improve things for a few days, then one day the battery was flat, jump started ok off the wife's car, all good for a few more days, then flat again, so replaced with shiny new Bosch S5, again all ok for a few days.
Problem - last week whilst leaving friend's house on a particularly cold night, turned key, dashboard lights all come on ok but I get a "tick tick tick" noise and no engine start. Tried again, dashboard lights ok, but no mechanical activity at all.
Bump started car down handy slope, all good, started and drove ok for a few more days, then again got the "tick tick tick" noise one morning but no ignition, followed by nothing (dash all lit up correctly). Bumped it again, all ok, also started again off the key a few hours later, but yesterday back to getting the "tick tick tick" noise then nothing.
Any thoughts on things I can investigate further before checking it into garage?
I have already tried - hitting starter motor with hammer, checked the charge on new battery (12.6v when cold), tried jump starting it, none of which help, can usually get it to bump start if the hill is steep enough but get "glow plug warning", although this goes away once the car has been idling for a few minutes and does not reappear when I start it again off the key so I assume it is just a side-effect of not starting previously.
Feels like an electrical problem? The starter isn't particularly easy to reach, but plan to check wiring to it, have also seen some folks suggest checking the crank case earth.
Once I've towed it back up from the bottom of the hill, I will have a proper look at it in the daylight tomorrow.
