No year, way a shame. 1jz what, there are 3. ge,gte,fse
24valve, DOHC , got twin turbos?
inline 6 , 2.5L (unknown target country or EFI used)
do the 60k mile tune up.
(ignition off to on process) huh? bad starts , ( i do a battery of tests ) here is a stupid list. (can do 50)
LOL what a pun, battery not low? (a battery of battery tests? LOL.
no year, makes answers SUPER HARD so guess at 96+
ever run a scan tool on it, see if DTCS are there? if not; why not?
1: never tuned up, this decade or last 60k mile marker.
2: ISC sticking close, starves air and goes rich floods.
3: low fuel pressure
4: leaking or clogged (full or partial) injectors
5: ECT reads wrong, so fueling is wrong
6: flooding for many reasons.
7: weak compression on 1 or more cylinders.
8: leaking head valves.
9:cam belt slipped, see low compression x 6
10: spark parts bad, or timed wrong.
11: scan it, scan it scan, it.... but no year so cant help you.........

If the spark plugs aren't firing then you just have to follow it backwards. the spark plugs should be connected to a coil or distributor. The problem could be there.

check for a good spark first, if there is none look at ignition circuits its more likley this part,
it could also be the car alarm the immobiliser shutting of the ignition ""stops it getting nicked?"
try resetting the alarm if you take off pipe to carb and there is fule pumping out!!! fule filter is "ok" for starting up on!!! take care working with fule!
