demuire Posted June 5, 2006 Report Share Posted June 5, 2006 I have an SV21 Camry. It doesn't work. I don't know why. RACQ doesn't know why either. It's sitting in the middle of Brisbane city, and I probably can't keep it there forever, but RACQ will only tow it 10km... I drove it to work this morning (no issues), and now it won't go anywhere anymore :monkey: Anyway. Battery OK Starter motor OK Fuel pump OK Fuses OK Spark plugs OK Cold start injector OK Injectors getting power, but NO PULSE. What is wrong? Dead computer? That's the only part the RACQ dude can think of. :) Quote Link to comment Share on other sites More sharing options...
love ke70 Posted June 5, 2006 Report Share Posted June 5, 2006 crank signal? Quote Link to comment Share on other sites More sharing options...
Raven Posted June 5, 2006 Report Share Posted June 5, 2006 I'd suggest another ECU.... Quote Link to comment Share on other sites More sharing options...
thomo Posted June 5, 2006 Report Share Posted June 5, 2006 do you have an after market imobilizer fitted? Quote Link to comment Share on other sites More sharing options...
demuire Posted June 5, 2006 Author Report Share Posted June 5, 2006 Thanks for the replies... Crank signal? No idea, how do I check this? The cold start injector works when initially cranking, I would assume it is getting some sort of signal? I also get spark. Just no injector pulses. Raven: Yes, RACQ man's best guess was ECU. Will try to get one from the wreckers tomorrow. thomo: Yes it does, not entirely sure what it is immobilising, but unless the module is malfunctioning and immobilising only 1 circuit (starter works - and I know for a fact that that is one of the circuits it immobilises) then I'd be guessing it should be working? Unlikely for immobiliser to just be cutting out the injectors? Quote Link to comment Share on other sites More sharing options...
love ke70 Posted June 5, 2006 Report Share Posted June 5, 2006 well, how does your ecu get signal of where the engine is? is it by crank angle sensor, or some sensor in the dizzy. if this has packed itself in, the ecu wouldnt know when to make the injectors pulse. your cold start injector is triggered by water temp sensor and...is it the cranking signal? I'm not sure how to check if your CAS or whatever you have is playing up, other than swapping for a known good one. if ecu is cheap, try that, if it still don't work id be thinking crank signal gone kaput.

Toycrash Posted June 5, 2006 Report Share Posted June 5, 2006 Check that your dizzy is turning... And look what fault code your ECU gives. T and E1 jumpered Quote Link to comment Share on other sites More sharing options...
demuire Posted June 5, 2006 Author Report Share Posted June 5, 2006 Will check ECU code today. Check engine light hasn't come on, so doubt there would be a code, but who knows... love_ke70: I have no idea actually. It doesn't look like there is a crank angle sensor, so I'm guessing it comes from the dizzy... Quote Link to comment Share on other sites More sharing options...
demuire Posted June 5, 2006 Author Report Share Posted June 5, 2006 ECU code 51: Input Circuit error. Have not yet checked TPS, don't know which wire is for AC on the ECU, so next thing on the list in the Gregory's book is to replace the ECU. Resistance on dizzy pins checked out OK. Not sure if this means anything... Going to get another ECU today, I wonder how much they cost? Quote Link to comment Share on other sites More sharing options...
demuire Posted June 6, 2006 Author Report Share Posted June 6, 2006 Replaced ECU (wow, $50), no difference. Still reads error code 51. Checked TPS, it's fine. I have no idea anymore. Carton of beer to anyone who can come and make it go again. Will probably give a couple of tow companies a call later today and see how much it would cost to tow it back to Ipswich. I don't expect it to be cheap :faq: Quote Link to comment Share on other sites More sharing options...
Mr Hardware Posted June 6, 2006 Report Share Posted June 6, 2006 you know with RACQ you get the first 10 kays free then you pay for the rest RACQ cost - 10 free kays would be cheaper than some random tow company i'd reckon Quote Link to comment Share on other sites More sharing options...

demuire Posted June 6, 2006 Author Report Share Posted June 6, 2006 Have can of StartYaBastard, will give that a go. If that doesn't work I might go back and replace the ECU again, maybe the "new" one is a dud too? Who knows. Failing that, I think it's tow time.

demuire Posted June 6, 2006 Author Report Share Posted June 6, 2006 StartYaBastard had no effect. Which sounds like no spark, although when removed the spark plugs fire. Camry probably getting towed tonight. Quote Link to comment Share on other sites More sharing options...
