Ryan Heagney Posted March 14, 2010 Report Posted March 14, 2010 hello we have a link v5 with electronic boost control running link ignitor and 4agze coils wasted spark, a cam angle sensor, it was wired and started first pop ran perfect on a tune from the previous 4agte it had, while idleing a fuel pump seized and it ran out of fuel (it has not yet been driven) we fixed fuel pump and now it will not start at all, hot or cold, no matter what you do with the cold start value, it will not start hot either, we removed the cas and spun it around by hand and all the injectors are fireing and it has spark, once we did this it started straight away and ran perfect , but then when it went to idle it idled then as soon as the rpm dropped below 1000ish it died straight away, not cough and splutter and die , it just died, then wont start again, we have checked the cranking voltage and it is stil above 10v and the cranking speed is 200rpm, all the injectors appear to be working fine, it seems like the crank angle sensor is faulty so we replaced it with one we knew was perfect and it still does the same thing, any ideas would be greatly appreciated , we are at a dead end really, and it needs to be running for dyno by the weekend you can contact me on 0277575167 if it is easier cheers Ryan Heagney Quote
Simon Posted March 18, 2010 Report Posted March 18, 2010 On having a look at this ECU in-house it was found that the TPS was spanned incorrectly. On the V5 software there will be a fuel cut active below 850rpm at wide open throttle. This is to allow the clearing of a flooded engine. When cranking the TPS must read less than 80% for the injectors to work. Quote
