Firing up '03 TJ Tips
« on: September 06, 2017, 10:15:50 AM »

I'm after some tips Berties - after a longer than expected period we're finally getting close to being able to fire up the TJ again after much fettling and tinkering. Trouble is she's been sat for a couple of years now  :icon_rolleyes:

So - I could do with some recommendations in terms of steps to take before starting her up again. I'm guessing that while I could just stick the battery back in and try the key there may be a better/safer approach? :)

There's no coolant in at the moment as the radiator's been off so I'm wondering about just running water through initially to flush it through  :100:

...and to think it only needed a couple of minor tweaks when we got it  :hysterical:

If it has been sitting that long, I'd flush the block out and the rad. Check oil levels, a squirt of WD40 down each plug hole. Whilst the plugs are out, turn it over by hand to ensure the rings are not binding in the bores. Then spin it over on the starter without the plugs in. If it spins round nice and quick and pressure show on the oil gauge, then refit plugs. Drain the fuel tank. Replace fuel filter. Fill with 2 gallons of fresh fuel, and start it up!

Don't know about an '03 but earlier ones will loose their 'idle memory' when left with a flat or disconnected battery. They'll fire but not run; hold the gas on for a few minutes on a fast idle and the ECU will relearn.

Thanks for that gem - that may save a panic later!

The idle air control valve got stuck on my XJ 4.0 when it had been sat for a few months, causing it to idle very high. A quick tap with a hammer soon unstuck it  :003:
