Herro fellow Vlt people, have a Vlt and bought half done project. Actually 1/4 done project and trying to finish. Everything is back together apart from exhaust. Have a Microtech lt10s ecu with a red falshing light which if for air flow sensor(according to the microtech usb adaptor to my laptop), BUT have no spark from plugs. I have power to Coil (have tried x2coils 1off a car that was running) but wont spark to lead or plugs. Does anyone know how to change air flow sensor settings on lt10s or is it totally different to no spark? Im confused? Has anyone heard of this problem? Cheers! Anything would be helpfull guys! Some original photos have not been recovered yet.

Anything would be helpfull guys! you've left this statement so open ended you can start from 1000 places first check is amber light flashes on crank, that means your getting some kind of crank single you need to supply more info about wiring, where the lt10 came from etc etc Some original photos have not been recovered yet.

Cheers for the replies but worked it out, crank angle sensor was wired in backwards. Pulled the whole wiring loom out and checked over everything and all spot on now according to the Microtech LT series manual. BUT haven't got her going yet. Buying someone elses half done project is a challenge. For those interested in helping? It's a, 1986 VL Turbo RB30 Manual Forged pistons and rods 1mm oversized valves Stage 3 cam 80lbs injectors custom fuel rail Custom Intake plenum XF throttle body High rise manifold with T70 turbo Microtech Lt10s ecu Gizzmo adjustable boost controller Turbosmart FPR800 Variable fuel pressure regulator X2 Bosch 044 pumps and surge tank 3.9 diff with mini spool Bla Bla Bla Got strong spark now, good fuel pressure, Timing is spot on, Tps is working, injector pulse is good but still no bang? A mate reconds get a new crank angle sensor? Any thoughts out there or ideas would be appreciated. Cheers!
