Motor cranks but theres no spark, we tested the actuator it seems to be alright. Im gonna test the coilpacks right now.

the thing is when we pull the spark plugs out and ground on it on the block, crank the engine and the spark plug doesnt spark.

I checked the igniter, it seems to be alright.

also when we undo the plug it doesnt smell like fuel as been in there.

Could it be something that is cutting the fuel and ignition?

Is there something else im missing? Someone have a diagram of the connectors?

got the plug for the igniter plugged into the loom at the back of the head properly, same with the injector loom and injector plugs...have you checked the line for fuel coming out while cranking, if not perhaps pump, maybe fuse gone?

Check fuses (under dash) and relays (in engine bay). Check that the 2 relays behind theECU are switching when IGN -> "ON".

You should be able to hear the fuel pump priming at the initial IGN -> "ON".

      ER34 RB25DE Auto - Would a flush ever fix an "A/T" light?

      By thatjawncrazy · Posted

      interestingly enough, i found out the answer is yes. doing a flush did fix my recurring A/T light. it might have been because of the trans filter: but that doesn't really make sense to me. the fluid/filter was super dirty. would that increase the pressure in the lines and trigger an A/T light? does the car even have a way of detecting that? i have no idea. i've done 200+ miles after the flush and no A/T light. if my A/B solenoids went bad, i would think the light would've come on. shifts and drives way better now though...at 2k rpm instead of 2500...no hesitation and downshifts when i want it to.

      I vote go red. Only because I hate keeping gloss black clean. Was no worries helping out either! Glad you've survived the rain outs of QLD

      I would again like too thank Matt for his help in me sourcing the detachable hard top for the little red car, without Matt's assistance in inspecting it and locking it down, I can guarantee it would have sold before I could get up to see it,  and as that was the only available NC hardtop in Australia, I consider myself extremely lucky on multiple levels To say I'm more that happy would be an understatement And, it is 100% water tight, I drove through torrential rain coming back south, and by torrential, they type of rain that doing 40kph in a 110kph zone was a real thing, and even then, the standing water on the Hwy was deep enough to throw waves I'm also more than happy that the huge "BEASTS" that Matt calls dogs didn't eat me for lunch, I'm sure the sniffs and licks were more to "taste test" me, over being to friendly Now to work out what colour to get it painted, panel match, or gloss black........first world problems are real

      Actually I might have figured out. Looks like there is a tab according to google images but it's hidden. Silly me.
