mr2 -91 3s-ge conversion to -91 3s-gte

[Gimbaz]

hi i have made a conversion in my 91 3sge gti 156hk to a 91 rev1 3sgte turbo.
i cant get it to start. i have no spark.
it cranks over and it smells fuel etc but no spark.
bought new igniter and coil but no change.
i wonder if i need to make any rewiring as i have not changed the loom from left foot Place?
i have connected the looms together by the fusebox in Engine bay.
all the connectors are the same and fits straight in but maybe that not enough?
please help.
im thinking of buy Another ecu in case its broken but maybe that is not the firs thing to do.
cheers Daniel

Where are you?

[Gimbaz]

in sweden

[PW@Woodsport]

I was going to offer to get it running for free, but obviously impossible if you're in Sweden.

Check you have 12v ignition power on the Black/red coilpack/ignitor wires.

[Gimbaz]

yes i have 12v Power on those leads and coil and igniter is brand new.
i have checked without distributor by putting coil lead Close to Earth but nothing. i ussualy tickles in your fingers if you do that but not in this case.
cheers Daniel

[PW@Woodsport]

Are you sure the ignitor/coilpack is well earthed to the chassis?

Chassis loom (from the foot well to engine bay), engine loom and ecu all have to match (be from the same rev car) ... i did this and the car fired up ... had the same problem as you with a mismatch .. you can repin but i dont have the pinouts any more

[PW@Woodsport]

With all due respect, i've done dozens upon dozens of turbo conversions and never once changed the kickwell loom, i repin at the rear as it avoids a whole heap of other issues you encounter by changing the kickwell loom.

Yeah i get that Pual but if you dont have the pinout information to repin your stuffed .. i swaped out my looms for a matching rev2 set and it fired, no problems in 5 years+


You way is easier, its the info on how to do it thats hard to come by mate .


I had a rev1 car with a rev2 engine fitted , i went with rev2 looms and ecu .. worked great .. its just my experience right or wrong

[PW@Woodsport]

Yep it can work, no doubting that, but i get phone calls on a weekly basis from people who fall foul of changing the kickwell loom, other faults start appearing sometimes.

The repin info is all pretty basic in my opinion, most of the time it's just power feeds and the FC pin.

I honestly believe people don't do enough research, the info is all there in both looms they actually have right in front of them.

[2mad]

My original looms and ecu were rev1 ecu, rev2 engine loom and rev1 chassis .. swapped out the ecu and chassis loom for rev2 and bingo .. like i said i can out go from my experience obviously you have way more bud .

[2mad]

I should just add my car was a rev1 turbo .. if it had been an na like Paul said it might not have worked

hope you sort it and are boosting in no time

[Gimbaz]

Earth should be fine.
i cleaned the bracket etc used new bolts.
maybe there is some repin that is needed?
or the ecu maybe?

[2mad]

maybe there is some repin that is needed?

This buddy ^^ .. you need pinouts and instructions on how to repin from someone .

[PW@Woodsport]

Sorry if this is a really stupid question but it has happened before.... you are using a turbo ECU and not the NA one right?

[Gimbaz]

yes i have the turbo ecu that came with the Engine the 17322 ecu

[PW@Woodsport]

Are you sure the distributor plug is connected?

[Gimbaz]

yes its connected. but i have also tried to test the spark at the coillead againts Earth just to se if it jumps any spark at all.
but isnt it any repin needed really as i have not done any since the connectors fittet straight in.
Cheers Daniel

[2mad]

What looms are you using ... eg. rev1 N/A chassis loom, rev1 turbo engine loom and rev1 turbo ecu.

May be Paul can help with repinning if he new what you were working with

[PW@Woodsport]

To be honest if you're seeing 12v on the B/R wires on the coilpack and ignitor then no other repin should be needed to get a spark, assuming the ECU is powered up correctly of course.

Check your battery and ignition supply wires to the ECU which are found on pin 1 for B+ (W/R wire) and pin 12 for Ign+ (B/Y wire) of the far right ECU plug (22pin grey)

Is the CEL coming on with ignition?
