1991luminaeuro3.1 Posted March 5, 2007 Report Share Posted March 5, 2007 This car is still not running right after I got a different ecm,icm and coil packs. I'm starting to think it could be the fuel injectors. http://vids.myspace.com/index.cfm?fuseaction=vids.individual&videoid=2013033413 Quote Link to comment Share on other sites More sharing options...
1990lumina Posted March 5, 2007 Report Share Posted March 5, 2007 Are you throwing any codes at all?? Sounds like a horrible misfire to me...but I dunno for sure...that exhaust sounds pretty fucked up too Will it idle by itself without touching the gas pedal/throttle?

1991luminaeuro3.1 Posted March 5, 2007 Author Report Share Posted March 5, 2007 no not at all the check engine light isnt on. I dont have a diagnostic tool either Quote Link to comment Share on other sites More sharing options...
1990lumina Posted March 5, 2007 Report Share Posted March 5, 2007 If the light WAS on..all you need in a paper clip to pull the codes (jus t so you know) But since it isn't on, I dunno if there would be any codes in the memory or not... Does it smell of fuel when running?? Like running extremely rich? If you pull the plugs, are any of them black or wet with fuel? Almost seems like one cylinder isn't firing at all...maybe you have a bad plug? Quote Link to comment Share on other sites More sharing options...
1991luminaeuro3.1 Posted March 5, 2007 Author Report Share Posted March 5, 2007 The car was at a garage for awhile and they told me I needed another ecm but before i took the car to the garage it ran fine after running it for awhile it wouldnt start back up.

1990lumina Posted March 5, 2007 Report Share Posted March 5, 2007 Crank position sensor?? If it wouldn't start again after it was warmed up and your coils and ICM are all good...this would be the next thing I'd check for.... BUT - once it is worked up, use a spark plug tester and make sure you are getting spark at all 6 cylinders Quote Link to comment Share on other sites More sharing options...
1991luminaeuro3.1 Posted March 5, 2007 Author Report Share Posted March 5, 2007 I was also thinking that to but the garage told me it couldnt be that its probably some wiring problem and they dont wanna mess with it. Quote Link to comment Share on other sites More sharing options...
1990lumina Posted March 5, 2007 Report Share Posted March 5, 2007 I was also thinking that to but the garage told me it couldnt be that its probably some wiring problem and they dont wanna mess with it. It might have been John (GP1138) on hre he was having some issues that were pointing towards the CPS..and it turned out the wiring coming from the CPS had some melted insulation and was shorting to the engine block..dunno it could be something like that too....never thoguht of the wiring :oops: Quote Link to comment Share on other sites More sharing options...
Euro Posted March 5, 2007 Report Share Posted March 5, 2007 wow, i think you should start looking fuel related for sure. Check the fuel pressure regulator, they don't always shut the entire motor down(like with me). It will make the car run like crap. Fuel filter? it sounds like your cat might be clogged too.. Maybe.those are just some things to check Quote Link to comment Share on other sites More sharing options...
1991luminaeuro3.1 Posted March 5, 2007 Author Report Share Posted March 5, 2007 Fuel filter was changed before it went to the garage my dad just called me and said that the number spark plug isnt hitting right. The cat has a hole it was like that when i bought it Quote Link to comment Share on other sites More sharing options...
1990lumina Posted March 5, 2007 Report Share Posted March 5, 2007 Which cylinder # plug? And what do you mean by not "hitting" right?? Like the timing of the spark is wrong, or is isn't sparking at all? Quote Link to comment Share on other sites More sharing options...
1991luminaeuro3.1 Posted March 6, 2007 Author Report Share Posted March 6, 2007 not sure thats what he said lol i guess now it wont start Quote Link to comment Share on other sites More sharing options...
White93z34 Posted March 6, 2007 Report Share Posted March 6, 2007 well if i were you i would replace the crank sensor. when i got my euro lumina it ran like complete crap then finally quit starting altogether till i replaced it. it sounds like it is trying to stay running. how old are the plugs and wires?

1991luminaeuro3.1 Posted March 6, 2007 Author Report Share Posted March 6, 2007 I guess the plugs and wires are new the garage said the changed them. How much are crank sensors. The cat has a couple holes in it was like that when I bought it. Quote Link to comment Share on other sites More sharing options...
White93z34 Posted March 6, 2007 Report Share Posted March 6, 2007 a crank sensor runs around $20ish but the more i think about it, i'd consider cleaning your IAC, or replaceing it altogether. that runs about $30 Quote Link to comment Share on other sites More sharing options...

RJansen658 Posted March 7, 2007 Report Share Posted March 7, 2007 Not to be an ass, but it isn't the crank sensor. It would not have a decided miss if it was the crank sensor, in the latter part of the vid you can hear clearly, and it has a decided constant miss, not a syptom of a crank sensor. The ignition system on the 3.1L MPFI's is a waste spark system, so if it was a coil or ICM miss it would be on at least two cylinders. I am a mechanic and judging by the line your mechanic told you.... I'd have to say he knows whats wrong and doesn't wanna tell you cuz he just put all those ignition parts on. Don't waste time throwing parts at it until you do a compression test. Sounds to me like a burned/chipped valve. A compression test won't cost anything, you can rent a tester for free at autozone... Good Luck Quote Link to comment Share on other sites More sharing options...
1991luminaeuro3.1 Posted March 7, 2007 Author Report Share Posted March 7, 2007 the mechanic didnt do nothing to the car only put the other ecm in thats it. He said he was done messing with it thats why my dad is messing with it now hes a mechanic also but ive been wasting money on this car and my dad has been putting them on. The car is for sale at this point and I dont think the car will make it to autozone Quote Link to comment Share on other sites More sharing options...
White93z34 Posted March 7, 2007 Report Share Posted March 7, 2007 Not to be an ass, but it isn't the crank sensor. well, not to be an ass but... i'm going on what i have found myself. when i bought my euro i had every "mechanic" (and i am one myself so don't go throwing stones) i talked to about its misfiring, stalling, hard starting, and failing to idle properly. told me that the crank sesor could not be it, "because it either works or it does not". well after it was all said and done, i ended up removing one heavially cracked and damnaged crank sensor from my engine and low and behold it ran perfect afterwards i am not saying that "OMG IT IS THE CRANK SENSOR LOL" I am saying that it is a place to start i'm also asumeing here that the plugs/wires are fine and have no cracked ceramics on them. If i were there i would: check plugs/wires check to be sure they are pluged into the coils right use a timing light to see if all cyls are getting spark. remove/clean the IAC replace crank sensor ( i say that because i have spares to change with, and it is easy enough to get at on a 3.1) compression check Quote Link to comment Share on other sites More sharing options...
1991luminaeuro3.1 Posted March 7, 2007 Author Report Share Posted March 7, 2007 I might just get a crank sensor cause the garage told me that it couldnt be that. Quote Link to comment Share on other sites More sharing options...
1991luminaeuro3.1 Posted March 7, 2007 Author Report Share Posted March 7, 2007 Also I should say the reason why i got a different icm cause it was dead i had it tested at autozone. Quote Link to comment Share on other sites More sharing options...
Crazy K Posted March 7, 2007 Report Share Posted March 7, 2007 change the CPS. they are often battle worn anyhow so even if it isn't the solution, it could soon be a problem. I've found that the injectors sometimes can be at fault. have you ran plenty of injector cleaner throught the engine? Quote Link to comment Share on other sites More sharing options...
1991luminaeuro3.1 Posted March 7, 2007 Author Report Share Posted March 7, 2007 I think my dad put in 2 bottles of injection cleaner. In a couple days I might go pick up a crank sensor and hopefully it helps. Quote Link to comment Share on other sites More sharing options...
1991luminaeuro3.1 Posted March 7, 2007 Author Report Share Posted March 7, 2007 My dad talked to some guy today from autozone and they said its probably one of the injectors they told him to talk off the plenum and have someone roll the car over to see if gas is coming out of them or something like that. I was looking around online for cheap injectors and found this one. Would that be a good brand to buy? http://www.autopartsauthority.com/parts_catalog/buy.php?make_text=chevy&model_text=lumina&ml=lumi-euro-001&year=1991&part_name=fuel_injector&brand_name=cvu&make_code=CV Quote Link to comment Share on other sites More sharing options...
