i've been using a map recently that seems to start the car sometimes but other times no luck



what should the ignition be like for 0rpm 500rpm?



how many ms of fuel am i shooting for with 850cc primaries? would it be easier for me to put the 550cc primaries back in?

your timing for cranking should be 5btdc*, that spec is in the manual. so i usually make my 0-500 map 5btdc too.



the injector ms at say idle should be 1.9-2.4ish, mine changed a lot when i put the cat on, so with a big bp you might wanna start on the high end.



also if it has a hard time starting bump up the primer map



*if its really cold 0btdc will crank over faster

my 0rpm map is like 6BTDC



my 500rpm map is like 20BDTC, you think that is the problem?

i replaced igniter, still i'm not hearing it fire off



i don't have an extra pair of hands to try the spark test



plugs look nice and shiny...

Timing light can be your extra hands. Hook it up and put it somewhere you can see it.

yah i made a little wire so i can crank the engine over from the bay, i think on the fd they have something like that in the diagnostic box

power wire to coil packs wasn't hooked up



new plugs + atf + fixed that wire = she's got 20miles on her now https://www.nopistons.com/forums/pub...IR#>/smile.png
