Microtech Issue - Was Fine Now Won't Start

Hey guys, our track miraculously won't start now once I hit the button

Its a forged RB25

Microtech LT12S

GT35R

etc etc etc

Now when I turn the key it cranks and cranks forever but will not fire

There is no spark from the Splitfire coils, and the injectors do not tick

When the ignition is switched on, with CAS removed from engine, and I spin the end of the CAS - both the injectors and coilpacks tick, however when I put the CAS back in the engine - theres nothing

I am bamboozled - have replaced CAS, and Ignitor to no avail.

I am wondering if maybe tehre is a voltage drop somewhere in the electrics of the car???

Any idea or things to check would be great!

Check the wiring for breaks going into the CAS. Maybe by removing the unit you are bridging a broken gap in the wire.

Long shot but it's the first thing I would check.

Also make sure the drive on the camshaft is still there.

Pretty much there are lights on the side of the ecu, pretty sure the red one flashes when there is a problem. If it flashes, check your hand controllers error log screens (screen 33 off of memory) and it will show what error options there are.

ErrorChk1 is for air temp, crank angle, home and ref

ErorrChk2 is for MAP, RPM, TPS and DC volts

See what it says from them and start from there.

check your fuses

Mine was a stupid blown fuse (yes I did check them first)

same thing i could take the cas out turn it and there was ticking only problem was i couldnt get a spark (occasional weak spark)

but when we looked at fuses again there was a blown one

changed that and away she went

I have a handset controller but the screen died months ago - it occassionally shows some info - i have used another controller on the ECU and it works fine so I guess my controller is only good as a paperweight now

I checked all the fuses like 10 times - theres only 5 in the cabin for the whole car :D

Highly unlikely, but I had an issue with mine recently where the green wire for the fuel pump relay wasn't working, I ended up wiring the relay straight to earth, till I can either get it fixed or find a better solution.

Auto Sparky who re-wired teh whole car is coming out tonight to look at it - jus seems weird that teh CAS when spun by hand makes the coilpacks emit spark and injectors tick - which would make me think the ignitor is fine - however once u try and crank the car, the CAS does nothing. I have watched cranked engine with no CAS fitted and the end of the cam definitely spins :D

As the WOR57 stated is the drive inside the cam engaging into the cas locater?

Check for bad electrical contacts if you sad that when you remove the cas it triggers the inj's then it sound like bad conecction

the keyway in the end of the cam spins, which in turn I would assume spins the end of the CAS.

      That looks good, but I think you're going to need much beefier side skirts now.

      new 1.5 LSD issues/concerns

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
