20v wont start

[Dom-AE71]

my 20v in my AE71 wont start

basic rundown,

Microtech LTX8
just swapped originaly injectors back in
new plugs
bosch coil packs

the car has spark and its getting fuel, injectors are pulsing, the car cranks but doesnt fire, it semi fires like a splutter at first then notthing

any ideas?

[Hokey]

have you checked the timing?

[TA-022]

plug gap and / or timing???

new injector o-rings? greased the o-rings???


*note* my mechanic mate is spitting reponses at me here

[Dom-AE71]

that was the only other thing i could think it would be BUT you can adjust the timinig using the microtech and its easier than trying to get behing the head to loosen the dizzy but i dont have a handset

its not too hard to get in there to loosen the dizzy. use a flat ring spanner and you'll be able to get to it.

ooww may have your answer!
You said you just swapped the std injectors back in. Did you adjust the impeedance setting on you ECU back to the Std impeedance ( ohms )?
or are they the same impeedance?

[The Last Streetfighter]

Air + Fuel + Spark + Timing. What else is there?

[Hokey]

Timing being the key there cause the other two are useless without it

:S no idea. anybody know?

seems the crank alot smoother and feels like its having a better go. played around with the dizzy to no avail. might =have another go and change the order of the leads around jusstt for fun.

sideshow is coming out on sunday

[Dom-AE71]

ok sideshow came out

we put the 1JZGTE injectors back in, it started with the 20v ones but the map was setup for the 1J ones and seemed to run alot better on them also.

the main problem was actually my battery, although it had an ok charge it was pretty old and shitty and he told me that when the voltage drops too much the microtechs go a bit funny.

so in short the car runs i had everything sweet except for a shit battery. sounds tough as too with jsut the extractors!!! hehe

[TA-022]

ah... always test voltage on crank .. drops below 10volt mean batt flatery.

good to see its solved!

[Adam_Cressi]

damn batteries

[Dom-AE71]

drove it up to the exhaust shop.

meh i have the BIGGEST head ache.

after trying 2 different battery braces and then modifying one of the brackets i FINALLY got it mounted and solid in the boot and in the box. pics once i get the car back
