Testing Rb20 Coil. Car Suddenly Wouldnt Restart. Adding Lead To Coil To Connect Spark Plug

hi mates have a problem with my rb20 hilux that started this afternoon. I started it up and reversed out my driveway. car died when I put the clutch in to go from reverse to neutral (does this a lot when cold. usually restarts straight away. CAR HAS HALTECH E11v2 so prob cold start tune). today it didn't restart. cranked for ages trying to get it going but wouldn't go and battery got too flat.

I changed the spark plugs now so I know there good.

mainly what I want to know is how do I make a thing ive heard of before where you connect a spark plug lead to the coil pack then put spark plug into that like a common spark plug setup so I can look for spark to rule out spark issue. im not sure how to connect it onto the coil

thanks for now mates

I would say you have no fuel then either.

Do the usual, check fuses. Then i would pull cas out and turn by hand to see if the injectors click and I'd there is spark. Then you have to set the timing due to removing the cas.

What fuses should I look for? Since its an engine converted car the stuff is in different places and probably unmarked.

I get fuel pressure at the guage near the fuel rail so fuel pumps are going I believe. Dunno bout injectors.

Setting he timing is going to be shit I rekn. Apparently aftermarket ecus don't set the timing off the Induction loop thing? And I don't know what they have set it too. Or will it just be tdc in regards to setting cas timing?

Like you said due to conversion what fuses do you check? If you don't k ow no way will I know.

The fact the pump is priming might mean the ecu Is turning on.

Fuel pumps wired to start with ignition is bad. Very bad in a crash. Should be controlled via the ecu.

Yea probs bad. I suspect that because they just run constantly once turn the key. Doesn't turn off when priming. Hopefully my ecu isn't dead. I don't believe the e11v2 has any lights on it so can't get quick idea if its getting power

I've done some more looking and thinking.

I hooked up spark plug to coil and prob have no spark.

Then removed spark plug and no fuel on it

I connected another cas I had (unconfirmed weather good or not tho) and turned it by hand with key in the on position. Nothing happened. No spark no injector noise.

My next thinking is I want to check power getting to the ecu and then follow from there. Problem is the haltech e11v2 doesn't have any lights in it to see if its powered up. Is there a way to check power to it?

It's a patch connector thing so the standard ecu plug is still there intact. I am now thinking of obtaining a standard rb20 ecu just to see if it lights up as my test for power getting to the ecu.

Any other ideas mates? Just bought house. Ment to be selling car. dream boats f**ked :(

did some more testing. didn't need standard ecu. I checked it with multimeter. has power.

what would be the next thing after the ecu I could check to make sure power is going out of the haltech ecu?

      R33 GTS25 NA - Stalling when vehicle is at operating temp

      By DRoc81 · Posted

      I removed the IACV, cleaned it and reinstalled.  I found a video on youtube that helped with the whole process, the guy then said the idle needed to be set, so the process was to get the vehicle up to operating temperature, unplug the TPS, set the idle screw in the IACV so the RPMs were around 600, then plug the TPS back in.  After I reinstalled the IACV, the car started (because, it was a cold start), once it warmed up, the car died, I adjusted the idle screw to see if that helped anything, it did not, I had to wait about 3-5 minutes, then the car would start back up. Only to shortly cut out, and only crank.  I loosened the TPS to see if adjusting that would do anything, and when I would rotate the sensor clockwise, there was a humming noise, but it would go away when I got the sensor in the horizontal position.  It only made the hum noise with the key on.  What do you guys think? 20250414_172604.mp4

      Troubleshooting - motor wont turn over

      By Murray_Calavera · Posted

      Quick update.  The engine grounding strap was replaced, the engine is now happily running.  Tested the voltage drop before replacing the strap, was about 1.2ish volts down between engine to battery, chassis to battery. With the new grounding strap, pretty much no voltage drop at all.

      Mistakes were made, my R34 Story

      I was chatting with an ex SAU person who is involved in chooning euros now. He was saying the factory cars like Audi VW etc have something like 2000 tables that the ECU uses for getting everything "just right". Compare that back to any aftermarket ECU, and you'd be hard pressed to surpass 50 lookup tables. Even the Ford Barra engine has a few hundred lookup tables to run it (and they're still working some tables out too!)

      Grab a temp probe, and probe each exhaust inlet runner with it sitting idling. Each one should be pretty darn close to the same temp. If you've got some reading higher or lower than the others, it's likely either air flow isn't equal, or your injectors aren't equal to each other.   The other things to check, is from the wiring changes that were made, were any earth's or grounds moved/changed.   Lastly, for the strut brace issue. It's not perfect, but can you get away with slipping a washer or two under the strut brace to raise it, and it still clean the bonnet? If you can, work out the height you need, that the motor can't torque up into, and get a spacer made for each side.
