dangeestarlet Posted November 14, 2014 Share Posted November 14, 2014 (edited) Hi just put a new engine in my starlet and as soon as it starts to come on boost it spluttere like mad and pop and bang, it's overfilling like mad and black smoking , done a diagnostic and it says coolant circuit incomplete and map sensor circuit, any help would be great Edited November 15, 2014 by dangeestarlet Quote Link to post Share on other sites
daniel_g Posted November 14, 2014 Share Posted November 14, 2014 Sort fuelling and swap the MAP sensor for another one. Also make sure the vac to the sensor is in good condition.Then onto ignition checks if that doesnt sort it. Quote Link to post Share on other sites
dangeestarlet Posted November 14, 2014 Author Share Posted November 14, 2014 It has stock fpr, means more money again for map sensor lol. It's puffing out black smoke and blowing hoops through my side exit haha. Quote Link to post Share on other sites
daniel_g Posted November 14, 2014 Share Posted November 14, 2014 You got leaky injectors then maybe ? Check the wiring to the MAP sensor. Thought youd have a spare MAP sensor knocking about with the amount of starlets you've had haha. Quote Link to post Share on other sites
dangeestarlet Posted November 14, 2014 Author Share Posted November 14, 2014 What do you mean by leaky injectors? They feel pretty loose on the rail, I checked everything when I moved houses lol Quote Link to post Share on other sites
mikey4410 Posted November 14, 2014 Share Posted November 14, 2014 has the map circuit had a fcd wired in at sumpoint ?have a check over the wiring near ecu.also I have had a shit missfire and not allowing to boost before and it was a fuse blow in fuse box. Quote Link to post Share on other sites
daniel_g Posted November 14, 2014 Share Posted November 14, 2014 If the injectors are leaking too much fuel into the combustion chamber and overfuelling it. Theres only really a few things it can be when its shooting out pure black smoke. Quote Link to post Share on other sites
mikey4410 Posted November 14, 2014 Share Posted November 14, 2014 check all fuses.then check all vac lines.and as I said check all wiring around the ecu for a poorly fitted fcd or similar Quote Link to post Share on other sites
dangeestarlet Posted November 14, 2014 Author Share Posted November 14, 2014 Ok thanks , it's got a hks actuator and the vacum is looped onto turbo ? Is that right? And the only other vaccum I got is map sensor to inlet, il check ecu tommorow , the only thing I can think off is I ain't got no temp sensors plugged in as the engine I had was a 98 spec and mines a 96 with different plugs Quote Link to post Share on other sites

Stu Posted November 15, 2014 Share Posted November 15, 2014 You need to have the water temp sensor plugged in for the ecu or it will run as described above if at all. Quote Link to post Share on other sites
dangeestarlet Posted November 15, 2014 Author Share Posted November 15, 2014 Done temp sensor now, it's giving codes , map sensor, air temp sensor and coolant sensor Quote Link to post Share on other sites

patman Posted November 15, 2014 Share Posted November 15, 2014 Looking at them flames mate are you sure it's not well over fueling? Quote Link to post Share on other sites
dangeestarlet Posted November 16, 2014 Author Share Posted November 16, 2014 Yeah it iverfuelling like mad lol Quote Link to post Share on other sites
mikey4410 Posted November 16, 2014 Share Posted November 16, 2014 A typical question would be what are ure afrs ? And the typical answer is I havent got a afr gauge.This would tell you an awful lot, but on a serious note that looks like you have anti lag and looks sick.prob not doin car to much good though.

dangeestarlet Posted November 16, 2014 Author Share Posted November 16, 2014 I ain't got a gauge no lol, would it be fuel cut by any chance? Quote Link to post Share on other sites
mikey4410 Posted November 16, 2014 Share Posted November 16, 2014 Possibly but they way your making it do whatever it is in he video you wana hope it's not as you have poss done some serious damage. Quote Link to post Share on other sites
dangeestarlet Posted November 16, 2014 Author Share Posted November 16, 2014 She's running abit better today, something's definitely not right tho Quote Link to post Share on other sites
dangeestarlet Posted November 17, 2014 Author Share Posted November 17, 2014 would the ignition timing cause this? Quote Link to post Share on other sites
satyrs Posted November 17, 2014 Share Posted November 17, 2014 (edited) hiya, im no glanza expert in any case, but i am technician working at VW/audi. to break it down step by step. engine fueling is done by the ecu what needs to following sensors to do a correct engine cycle.-cranck pos sensor-engine rpm-air amount/ air temp-cooling temp-trothle pos-lambda sensor-knock sensor if any of those sensor gives a faulty ready the ecu will adapt to that false reading.after diagnostics you tell us that you have 2 faults: Map sensor and coolant temp. the coolant temp sensor gives a signal to the ecu that your engine is warm or not. this means it will use more fuel when cold readings and "less" at warm readings.try to find the sonsor qualifications of how much resistance at what temp it should give. so you can test it outside of the car. if it keeps telling the ecu that he is cold he will use more fuel. would it be enough to cause a malfunction as this.... duno cant tell.... the second is the map sensor.this measures the amount of pressure in the manifold, what is needed for a correct amount of fuel.this sensor can also be measure by a handpomp. most of those sensors have a liniar volt measurement. ( like: 0.1bar=1volt 0.2bar=2volt)check if those sensors are functialy properly and check the ecu if it gives any codes. after that happy hunting on the rest of the sensors. hope it helps, grtz, Wouter (p.s. im not english so dont mind the typo's) Edited November 17, 2014 by satyrs Quote Link to post Share on other sites
dangeestarlet Posted November 17, 2014 Author Share Posted November 17, 2014 Hello and thanks for your help, I have purchased new coolant sensors and map sensor along with new injectors and new coil and igniter , I will also gap the spark plugs to correct gap and also set ignition timing, it is probably something simple and I will let you know how I get on when I fit new parts and try it again, thanks again for your help : D Quote Link to post Share on other sites
Stu Posted November 17, 2014 Share Posted November 17, 2014 Done temp sensor now, it's giving codes , map sensor, air temp sensor and coolant sensor All of those sensors share the same sensor earth array fed from the ecu. I'd check the wiring and its pretty uncommon for the sensor to be faulty. Does it have a fcd on it by any chance? Quote Link to post Share on other sites
dangeestarlet Posted November 18, 2014 Author Share Posted November 18, 2014 Is there any earths to ecu? As I swapped ecu as I had a jam one in before ,it looks like it's had a fcd before as wires have been cut and joined Quote Link to post Share on other sites
