MS PnP 90/93 modded with VTPS won´t start
I already posted thsi on m.net but it seems nobody ever before had this problem:
Hi,
got a little problem out there.
My car (see it as a 90-93) had a complete engine rebuild during some months til now. Until restart, I did the VTPS mod to the MS meanwhile.
Now back on and all together again the car doesn´t start at all.
The fuel pump doesn´t start and the engine therefore doesn´t fire up.
I already wrote Matt at DIY AT and he told me to disconnect the normal TPS which is fitted.
I did and nothing happend.
I bridged GND and F/P on the diagnostics connector under the hood, the fuel pump permanently runs (and delivers fuel to the rail), but the car doesn´t start.
The car is fitted with a LC-1 (which I ran together with the unmodified MS PNP before the rebuild) and NO OEM O2.
Is there something I forgot??
I tried to start with a 90`s ECU (with AFM) which I have, but the same.
I also connected the 10A fuse under the hood, which is necessary for the OEM ECU (which has to be removed when using the MS PNP).
I have a Fuji ITB Kit lying around which should be installed when the car has proved for 1000mls that it´s all ok with the engine.
Would be glad for help
It makes me sad.
My laptop has connection to the MS, so that thing is working.
I tested the MS with removed AFM and stock ECU with AFM.

Think we got it.
Got the message today that Q5 on the daughterboard was dead. So it seems I forgot the fuse in the fuse box under the hood...
I did a firmware update, but with the ignitor plugged off.
For security I already changed the coils and will do this to the ignitor, too. For cases like these, I´ve got them things lying around.
