Paul-90 Posted April 20, 2014 Share Posted April 20, 2014 Hey we are having a problem getting the supra to start after we had the engine out to fit the whifbits turbo conversion. The car is a 94 jap NA. It ran perfectly before pulling the engine out. The car lay with no battery in it for a few weeks. The car has spark, fuel pump is priming and there is power going to the injectors however the injectors are not firing. The car had a cheap aftermarket alarm on it that we pulled out hoping that would sort it however it didnt. We think the car may be immobalized however i only have a normal key for it. Does anyone have any ideas what may be the problem? Quote Link to comment Share on other sites More sharing options...
David P Posted April 20, 2014 Share Posted April 20, 2014 The missing signal would appear to be on the earth circuits of the injectors, which is controlled by the ECU. If that helps. Quote Link to comment Share on other sites More sharing options...
Guest Roger NE Posted April 20, 2014 Share Posted April 20, 2014 Have you checked the fault codes ? That should give you an idea what the problem is. Most immobilisers interrupt the Starter Motor solenoid and/or the ignition and/or the Fuel Pump (mine does all 3) . . . but if you have checked that those are all working, I presume that's not your problem.

Paul-90 Posted April 21, 2014 Author Share Posted April 21, 2014 It has now started. Checked all the connnections and earths. All seemed ok. Still wouldnt start so decided to just hold it turning over till it either started or the battery died lol. It finally started. It is however a little slow to start. Any one any ideas why?

Fizzy T Posted April 21, 2014 Share Posted April 21, 2014 Sounds like maybe fuel wasn't getting through. Quote Link to comment Share on other sites More sharing options...

Probably the easiest step to take is to put a multimeter on the battery terminal s to see volt drop. Battery voltage should around 10v and above when cranking the engine. This is to check the starter motor isnt drawing too much due to high resistance. ..StartingSystems-2.pdf Edited April 21, 2014 by Tayfun.tugra (see edit history) Quote Link to comment Share on other sites More sharing options...
