mixmasterlex Posted March 18, 2009 Share Posted March 18, 2009 I have a Celica with a 3tgte. When cold it fires into life first crank. Boom, instant as shit. When shes warmed up if I turn the car off, then turn it on again straight away or within a min, she starts no problems. If I let it sit for 5min or so thats when it becomes really hard to start. Crank it over for a while and eventually it will fire up. What are the usual things that could cause this? Also if you have to keep cranking it (for 20seconds or more) it eventually starts to smoke a bit while its turning over, but as soon as it fires up the smoke goes away. Heat soak issue? Seems like its probably fuel or injector related? !!! Quote Link to comment Share on other sites More sharing options...
84_S12 Posted March 18, 2009 Share Posted March 18, 2009 Ignition module? They're a solid state device often found hiding between your dizzy and the engine block which of course makes them prone to heat soak... I could be wrong though it might pay to wait for someone more conversant with Toyota engines? Quote Link to comment Share on other sites More sharing options...
sheepers Posted March 18, 2009 Share Posted March 18, 2009 what happens if you start it when its cold, let it idle for like 30 seconds and then turn it off, wait the 5 mins and try to start it again? will it start straight away or do you get the same problem? sheepers.

mixmasterlex Posted March 18, 2009 Author Share Posted March 18, 2009 not sure sheepy. Ill give that a go tomorrow morning What are ya thinking? Quote Link to comment Share on other sites More sharing options...
sheepers Posted March 18, 2009 Share Posted March 18, 2009 it will differentiate between a "heat soak" type issue (probably electrical) and a possibility of over fueling. toyotas like to flood the shit out of themselves when they are cold, no such a flash idea when they are hot. could be something to do with the cold start injector, or the temp sensor that controls it. anyway, its just a bit more information to go with to try to help you fix it. let us know tomorrow. have you thought of doing a 4M conversion? no pesky cold start issues with an M, cauz they dont start any time. definitely worth thinking about sheepers (who LOL's himself) Quote Link to comment Share on other sites More sharing options...

Wouldn't a 4m be a step backwards? Or were you joking? It does sound like its flooded when she trys to start when warm. Looking forward to getting all these issues sorted anyway. I was thinking about selling it on but as I get things on it done I just want to keep it more! Quote Link to comment Share on other sites More sharing options...
sheepers Posted March 18, 2009 Share Posted March 18, 2009 4M = loss. let us know how it goes with the above mentioned shit. Quote Link to comment Share on other sites More sharing options...
forced Posted March 18, 2009 Share Posted March 18, 2009 So who's the dickhead that deleted my post? Which said....... A "pro" would check for faultcodes at the ECU. If you don't know how to do it...... jump over to toyspeed. If it doesn't have built in diagnostics then manual diagnostics would be the way to go by reading the ECU pins with a voltmeter, you'd need a workshop manual though. There's easier things to check first, like sparkplugs..... wet, dry, black or white. That will give an idea to whether it's fuel or spark problems. The igniter as mentioned would be a real possibility. Unlikely to be a temp sensor, you'd expect in that case for the cold start injector to stay on all the time, or at least run crappily when running.

Steve Good luck 3tgte runs analogue injection much the same as my MTEU, fault codes didn't come along until the second gen 5mge's etc. The cold start injector could be the culprit this is a separate system to the ecu completely on old stuff just a thermostatic switch that makes it piss in fuel under certain temperature Don't know who deleted your post but you know the way you go about giving out your information rubs people up the wrong way around here Quote Link to comment Share on other sites More sharing options...

(delete etc) yea im not a pro on toymotor systems but id have a stab at the cold start injector control system (whatever that includes) mainly the temp sensor .. they cause hassles soo quickly edit** . spence beat me to it hard by like miles... guh Quote Link to comment Share on other sites More sharing options...
Spencer Posted March 18, 2009 Share Posted March 18, 2009 YEa you can simply pull it off the car run some wires to it drop it in ice water chuck it on the stove and heat it up and check the resistance. Check the values against a repair manual (I think theres one on line) The problem could be something else but check the temp senders first and get that out of the way maybe Quote Link to comment Share on other sites More sharing options...
mixmasterlex Posted March 18, 2009 Author Share Posted March 18, 2009 Ok, fired it up this morning. Let it idle for a min. Turned it off. Waited 5mins, fired up straight away again. So sounds like a heat soak issue... Quote Link to comment Share on other sites More sharing options...

If you don't know how to do it...... jump over to toyspeed. Steve i deleted it. because, as with everything else you post on this forum, it was redundant (as pointed out by Spencer and others) and your language and manor was, as always, abrupt, confrontational and derogatory. notice the way you have written "whos the dickhead" at the beginning of your post. this is exactly the sort of thing that I'm talking about, and is going to get you banned very shortly. pull you head in, be a bit more friendly and helpful or fuck off. sheepers.
