Any help would be appreciated... 91 loyale, 1.8l fuel injection 140K on motor a friends car, just stalled and will not start. It ran smooth before hand. Plugs were bad and completely black, I replaced with new- gapped to .44 and new fuel filter. Fuel pump works fine. 3/4 tank of gas It will turn over, but won't catch. However, while turning over it's blowing blue smoke from exhaust. I don't have a meter to check the coil for connectivity. Any suggestions?
try starting the car with the gas pedal held down, or disconnect the injector harnes. my bet is that the car is badly flooded, blue smoke means there is some firing going on?
how much blue smoke is coming from the exhaust? I have a pretty fair meter if you would like to borrow it. Is the new fuel filter installed in the correct direction? can you check the crank postition sensor, has the timing belt been serviced?
Filter is in properly, blue smoke was pretty hefty at first, but now it doesn't even catch at all. Couldn't check the crank position sensor, and the timing belt has not been serviced that I'm aware of.
Blue smoke is an indicator that oil is being burned. Hopefully, your cylinders aren't flooded with oil. Check your oil (using dipstick) and see the condition of the oil, if you're low on oil, or if there's anything else floating in it.
SSSBB will make a motor run... Suck. cranking vacuum Squirt. injector pulse, fuel pressure, Squeeze. compression Bang. strong spark at the right time an Blow. clear exhaust. Broken timing belt?
timing belt looks to be intact. It's not cranking abnormally fast. Question....If I took the coil wire off the coil shouldn't I see an arch when turning it over...if the coil is good? I did that and NO arch. Nothing
you need to pull a spark plug cap, put a plug in the cap and touch the threads to the block. Then get a freind to turn over the motor and watch the plug to make sure it is sparking.
nope, that'll work, but there's an easier way. unplug the coil wire from the distributer and touch it to ground, and look for an arc are you getting a CEL? this sounds like a textbook crank angle sensor problem. I've got a few distributers you could swap in there. or there's a loyale in north side Upull, and an N/A XT in south side, both will have a distributer that will work (assuming it works :hsugh: ) this does also sound like a broken timing belt. get a flathead screwdriver and pry the edge of the cover open to check it.
Try this one... No spark, no injector pulse, no check engine lamp... Wait for it... Do the horns work? If no, check the fuse. Unplug both horns the replace the fuse if blown. ((Buried under the head lamps about where the turn signals are. I used to take the lower pan odd to get to them, others removed the headlamp assemblies. No fun either way)). The horns are powered off a fuse that also powers part of the engine computer. When (not if) the horn shorts and blows the fuse it causes a no start. Or I could be completely wrong...
I didn't phrase it right, maybe you figured it out, but you need to look for the arc while cranking. also check for power from both sides of the coil (use a test lead, one contact on one side of the coil, the other to ground. then try the other), if you don't have power there, it's probably the ignition amplifier under the coil, I've got a few of those you can try aswell. and yes, check the fuses....
Update K, thanks for all your help everyone. I beleive it's the coil, everything else checks out. I will grab a coil today (hopefully) and get this dirty little car out of my garage. Cross your fingers...
it's probably not the coil. there are a couple things that control the coil that fail much more commonly then the coil itself do you have power to the coil? are you getting a CEL?
thanks for blowing my confidence that i was on the right track...lol yes, power to the coil, but no spark on the main coil wire to distributor. that's whay i thought it was the coil
Update: okay, after looking further CHUX was correct, not the coil. However, I cannot tell you what it was/is...I took the coil out, put it back together....and gave it some starter fluid and what do ya know....it's now running. I let it idle for 15 minutes, shut it off and re started it a few times. FYI: I cannot figure out how to read the CEL codes on this car. I have the list of codes, but puzzled on how to interpret it. Here's where it's at....To start the car I must push on the gas pedal a bit....shouldn't have to, it's Fuel Injected. It idles rough at 500RPM, but revs smooth from 1K to 4K no problem. I checked with the owner, she stated the check engine light has been on for a year or so. (It's not flashing, just always on.) She also said it always ran rough at idle. Any additional thoughts? thanks to everyone that has helped out.....
Everything you need to know about ECU trouble codes: http://www.usmb.net/repair/?Current...icle&File=ARTICLE_3f2c055f4862e9.39782181.art probably the best article I've been able to find. Don't forget to connect the white connectors up by the fuel filter, it's just one wire, but if you don't connect it, you won't get all the codes. you have an '88 and later Single Point Fuel Injected model ibyougetanEGRcode
