rb25 refusing the start

[sil80drifter]

what would cause an rb to suddenly not start? after i spun out on track it just refuses to start now all of a sudden, its gettin fuel into the rail, the plugs are sparking but still no joy. Have checked intercooler pipes, afm, ecu, all wire/fuses etc but still cant find the problem, can anyone shed light on this???


was going fine up untill a blow out on the back left and from that point on wont start, its turning over perfectly but its not even trying to fire

Could be the cam angle sensor.

Ironic....I'm having the same problem this evening myself. Turned on car and was running fine. Took it for spin couple hundred metres coz I was checking if wheels were rubbing after fixing from my off in mondello. Got out left it idle for minute or two and it just cut out out of the blue and now won't tick over. It's getting fuel, has new plugs, piping, afm etc are grand too. sorry for the hijack man, but if some1 could help I would be getting out of a hole too

Throttle sensor id say just on plug a drop of WD40 and plug it back in happened mine before and this solved it. It only cuts out when you let it tick over but will run if you how the throttle?

Yeah if I let it tick over it will just cut out after 2 or 3 seconds. But when I crank it over and feather the throttle it will eventually start and if I keep feathering the thottle it will keep running but is very lumpy, misfiring and won't revc up high unless if I feather the throttle to get it to do it. Where is the throttle sensor on the rb?

I had a rough lap in my r32 in mondello and when i came in was spluttering and them wouldn't start, turns out I frayed the loom on full lock and it was messing with fuelling and spark and all! Maybe worth checking?

Its not the tps for me and the wiring under the arch is fine too. @Sil80drifter, did you figure yours out yet?
