dubchaser Posted March 3, 2004 Share Posted March 3, 2004 hello, i'm new and my buddy highly recommended using this site for help. I have a 91 loyale that is having trouble firing up. It turns fine though, just doesn't like to fire up. originally i thought it was just because of the cold and wet weather, but its warmer now and isn't starting at all. I was thinking it could maybe be the spark plugs and wires? anyhow, any suggestions would be greatly appreciated and helpful. thanks chase Quote Link to comment Share on other sites More sharing options...

calebz Posted March 3, 2004 Share Posted March 3, 2004 Start with the obvious. If you don't know when the last time a tune up was done, do a tune up.. plugs, wires, cap, rotor.. the usual suspects.. Report back when you have completed that. Quote Link to comment Share on other sites More sharing options...
TROGDOR! Posted March 3, 2004 Share Posted March 3, 2004 Is there any difference between starting on a cold engine vs. a warm engine? Quote Link to comment Share on other sites More sharing options...
myossfeece Posted March 3, 2004 Share Posted March 3, 2004 yeah in my opinion the warm engine would start easier becase, it's warm so the piston rings have sealed up the t-stat is open, the oil is warm, and the fuel lines would still be pressurized. When it is cold out I have to put my foot on the floor to get rx to start but once warmed it starts every time without the use of the throttle. If I don't floor it you can crank on it all day and it WON'T start ever, unless you cranked on it long enough to start warming the engine up. hope this helps.

konrad/soo Posted March 3, 2004 Share Posted March 3, 2004 is it MPFI or carb? i have mpfi and it's starting ALWAYS on the first turn,... just wait 10 sek. for the fuel pump to get the gas in right place and it goes( in -20 C too ) so check the spark plugs and wires , etc. good luck Quote Link to comment Share on other sites More sharing options...
torxxx Posted March 3, 2004 Share Posted March 3, 2004 if its a carb, try feathering your gas pedal.. I have to pump the hell out of mine every now and then to get it to start. take the airbox cover off the top of the carb, push the gas pedal all the way to the floor once and see if the choke closes. If not it doesnt, this may be your starting problem You could also try holding the pedal to the floor. (engine could flood itself out) I've also had this happen to mine. It does it right about freezing temp. If its fuel injected, dont try the first one you'll flood it. Pull your spark plugs, look at what color the tips are.. This will tell you if your running too rich or lean Quote Link to comment Share on other sites More sharing options...
calebz Posted March 3, 2004 Share Posted March 3, 2004 91 Loyale = SPFI Quote Link to comment Share on other sites More sharing options...
dubchaser Posted March 4, 2004 Author Share Posted March 4, 2004 ok subie experts, i did a spark plug and wire change, also changed the cap and rotar. I is still not firing up... not that it matters, but one of the spark plugs isn't going in all the way because the thread is all messed up. but we got it in as far as possible and connected the wire(didn't know if that matters or not or what i should do about that, i believe the previous plug also wasn't in all the way either, do i need to re-thread the hole somehow or any other suggestions), but at any rate the engine still isn't firing up. I'm thinking now maybe something with the fuel injection system. Also can water or moisture get in somewhere and prevent starting, because i live in eugene where rain is an everyday ordeal so there is a lot of moisture in there. anyway people, i'm needing a car! hope you can help thanks so very much, chase Quote Link to comment Share on other sites More sharing options...
MilesFox Posted March 4, 2004 Share Posted March 4, 2004 check to see if your fuel pump is coming on. you should hear it for a second once you turn the key on. you can also connect the green test clips, and the pump will cycle on an off, if the key is in the run position. the green clips will be under the hood for spfi, but if yours is mpfi? look under the steering culumn, behind the dash panel(like a turbo's) not to wuestion your intelligence, but is there an injector near each plug? MPFI? or does ithave a throttle bodt injector SPFI? anyway, start with fuel, or just pull the hose off the filter, and see if gas comes out when you turn the key on are you getting spark? check out the ign amplifier, the little round thing on the coil bracket check to see if the rotor turns when you crank it, but i doubt a timing belt would have broken from sitting maybe the water temperature sensor? but generally the car will start, but be hard to start when warm my buddy has an spfi sedan, it wouldnt start, spark or nothing in 20 deg weather, butr we came back the next day and she fired right up Quote Link to comment Share on other sites More sharing options...
dubchaser Posted March 4, 2004 Author Share Posted March 4, 2004 Its an SPFI, the rotar turns fine, its not the timing. we'll have to check the fuel pump out better still. what about that spark plug thread though, is there any way to fix the threading. the plug isn't going in all the way. also we think the fuel filter may be clogged, is that a big task to replace? thanks, CHASE Quote Link to comment Share on other sites More sharing options...
subaru_styles Posted March 4, 2004 Share Posted March 4, 2004 you'll have to use a heilacoil to rethread that hole in the block..... Quote Link to comment Share on other sites More sharing options...
torxxx Posted March 4, 2004 Share Posted March 4, 2004 when you say the plugs not going in all the way, are the threads stripped, or did you just bung up the threads? if it doesnt go in all the way, you could retap the hole. Just make sure you use the right size tap and use a shop vac to suck out the metal shaving out of the cylinder. Dont try starting it until you get that plug hole fixed.. You dont want a plug exploding out of the hole when you crank on it. 20 degrees is still high I think 12 is for SPFI non turbo static time it to 10 degrees and see if you can get it running from there. pull a plug and see if its getting spark. If not, you might have slipped a tooth on the T-belts Quote Link to comment Share on other sites More sharing options...
calebz Posted March 4, 2004 Share Posted March 4, 2004 Maybe its different for 86, but my 88 FSM says 20 degrees for SPFI.. Sorry torxxx Quote Link to comment Share on other sites More sharing options...
MilesFox Posted March 4, 2004 Share Posted March 4, 2004 20 deg for spfi, 25 for turbo, 8 for carb Quote Link to comment Share on other sites More sharing options...
rallyruss Posted March 4, 2004 Share Posted March 4, 2004 umm he meant the temp outside 20deg. but good now he knows where to set timing. somthing I think trogdor was tring to get at is the temp sensor. bad temp sensor or shorted circit will tell the car its hot when its not. and therefore lean it out. have you tried to start it using carb spray or starting fluid? that would really help decide if you have a fue or a spark problem. as for you you bunged up plug hole. ouch. they sell special taps at parts stores just for that. try that first to clean up the threads. if that does not work yeah you may need a insert . oh asfor keeping material out of the motor while doing the repair but grease on the tap (it holds the metal shavings) . then try vacuming after.

dubchaser Posted March 4, 2004 Author Share Posted March 4, 2004 yea we tried starting it with some B-12 chem tool, i think it was called. still nothing though, and i had the coolant temp sensor changed over the christmas break.... Quote Link to comment Share on other sites More sharing options...
Meeky Moose Posted March 4, 2004 Share Posted March 4, 2004 a real weak coil will do that too... just my .02.. hold onto the plug and have a friend crank it.. if it hurts a little, replace the coil, if it makes your fingers numb then its ok. p.s don't do it that way, but i would check out the coil.. might go get an accel for $40 or so.. btw my spfi wagon starts in about 3 seconds when its cold and you don't have to touch the go pedal.. in fact in my carbed hatch you get in, turn the key on, pump it once, and it fires up instantly.. also change the fuel filters.. they are easy to change and don't cost much..

dubchaser Posted March 4, 2004 Author Share Posted March 4, 2004 what is the accel thing your talking about for 40$? Quote Link to comment Share on other sites More sharing options...
Meeky Moose Posted March 4, 2004 Share Posted March 4, 2004 aftermarket performance coil.. any parts store has them.. if i remember right the part # is accel 8140.. come in chrome too Quote Link to comment Share on other sites More sharing options...
Buddythedog Posted March 5, 2004 Share Posted March 5, 2004 Everyone is right, check for fuel, take the line off and turn the key to on and it should spray out a bit, do this after it's run through the filter, I haven't heard of any getting so clogged that no gas gets through. If'n you have gas to the throttle body carb, good. Pull a plug wire at the spark plug and turn the engine over, if you've got spark, your timing belt is ok, because your rotor is turning, or just pull the cap, have a buddy crank the engine over and make sure the rotor turns to test the timing belt, if it doesn't move, that's your problem.
