Micah Posted December 1, 2006 Share Posted December 1, 2006 I'm recently noticing when I first start my car a strong smell of gas upon startup. Is this normal? The car has fresh wires and plugs from last summer along w/ timing belt and K&N filter. I cleaned the throttle body too. What could cause this? It almost smells like an outboard engine. EDIT: Had a thought, could it be the ignition system? How can I test the coils to see if they are putting out right? I assume I can use a voltage meter.

Micah Posted December 2, 2006 Author Share Posted December 2, 2006 So no one has ever noticed this? Quote Link to comment Share on other sites More sharing options...
Micah Posted December 3, 2006 Author Share Posted December 3, 2006 Alright, I figured out how to check the coils, but I don't know what the readings mean. I checked resisance b/w pins 1 and 2 (the input plug) and then b/w pin 1 and output then pin 2 and output. Here's the results: Coil 1(driver's side): Pin 1 to Pin 2: ~0.5 ohms + or - .1 ohm Pin 1 to output: 11910 ohms Pin 2 to output: 11910 ohms (ohm meter read 11.91 KOhms) Coil 2 (passenger's side): Pin 1 to Pin 2: ~0.5 ohms + or - .1 ohm Pin 1 to output: 11500 ohms Pin 2 to output: 11500 ohms (ohm meter read 11.5 KOhms) Are these readings within spec? I'm beginning to think that this may just be normal, but the car seems a bit weak when I turn off the a/c and idle forward in drive. Creeps forward very slowly at about 500 rpm.

jzz30 Posted December 3, 2006 Share Posted December 3, 2006 usually if a coil is bad you have constant bad gas smell and your car has a very hard time even moving along with a very rough idle. i will get back to you on those specs as my manual is not in reach right now.

Micah Posted December 4, 2006 Author Share Posted December 4, 2006 Thanks, That would be great! Quote Link to comment Share on other sites More sharing options...
jzz30 Posted December 4, 2006 Share Posted December 4, 2006 resistance between the 2 connector pins should be .4-.5 ohms and the resistance between the + pin on the connector side and the plug wire side shoud be 10-14k ohms. so you seem to be in spec! maybe you have a leaky injector that leaks a bit while the car is off and you jsut burn a little extra on start up before the cat is heated up...

Micah Posted December 5, 2006 Author Share Posted December 5, 2006 Sounds good. That sounds logical. Thanks for the help! Quote Link to comment Share on other sites More sharing options...
BrabusCClass Posted December 6, 2006 Share Posted December 6, 2006 I have a smell during startup. Im gonna change my plugs and wires and see if that helps. My buddy thinks I have a lazy cat and I should replace them if I want it to go away. I dunno. Quote Link to comment Share on other sites More sharing options...
Micah Posted December 7, 2006 Author Share Posted December 7, 2006 sounds good. I have new wires and plugs along with rotors and distributor caps and timing belt. I think i'm going to have the compression tested to see what's going on in the engine and see if there is excessive wear there. Quote Link to comment Share on other sites More sharing options...

I think i'm going to have the compression tested to see what's going on in the engine and see if there is excessive wear there. Maybe its your Catalytic converter. After some years Toyotas tend to have "lazy cats" where unless heated up they do not work properly. We run into this a lot in Cali since we have to go to smog tests. So basically you have to drive around a bit before getting a smog or else you fail. Lolz. Quote Link to comment Share on other sites More sharing options...
Micah Posted December 11, 2006 Author Share Posted December 11, 2006 I was thinking O2 sensors maybe as well. Or even the Valves may need some adjusting? I plan on having all this checked after I get my boat finished this month. Would it be the cats if it only happens upon startup because I thought that they had to be hot to do their job right. The car's not hot when it starts first thing in the morning and therefore not burning off the excess gas. I'm just worried that a lot of my gas may be going out the tailpipe. I am going to put some lucas fuel injector cleaner in the tank and see if that helps. Quote Link to comment Share on other sites More sharing options...
BlueSC400 Posted December 12, 2006 Share Posted December 12, 2006 If I never hear from you again, I am going to assume that your car has blown up and you are dead. :D Quote Link to comment Share on other sites More sharing options...

Cornwall Posted December 12, 2006 Share Posted December 12, 2006 If your only smelling petrol on start up, check your injector seals top the manifold when warmed up the injector and the fuel manifold expand and can seal up a leaking o ring that weeps when cold eventually the leak will be there when the engine is hot as well as the leak gets worse get the torch out and look along the inlet manifold when cold for wet bits Quote Link to comment Share on other sites More sharing options...
thmman Posted December 12, 2006 Share Posted December 12, 2006 I had a gasoline-like smell when I started my SC400. The oil pan needed to be re-sealed. Quote Link to comment Share on other sites More sharing options...
Micah Posted December 13, 2006 Author Share Posted December 13, 2006 The smell isn't in the engine compartment. It comes out of the exhaust. Can it still be the manifold/injectors if it comes through the exhaust? Quote Link to comment Share on other sites More sharing options...
