Starting Issues
Tried to start my Alero (2.4L) this morning and it did not start. At first, it started slightly but did not run smooth at all and died after 2-3 seconds. I tried to start it immediately after and it turns over fine, but as soon as engine takes over from the starter motor, there's a pretty violent shutter and it dies.
Any ideas what this could be caused by? It's pretty cold here, not sure if that would have anything to do with it. EDIT: I have had a code thrown for a minor EVAP leak. Haven't had the chance to address it, but maybe this could play a part in it as well? |

UPDATE: For anyone lurking. Pulled the coil pack and tested using an ohm meter. One bank read 0.5 ohms and the other 0.4 ohms. On my way to get news coils, plugs, and boots. I'll update after that.

UPDATE: Plugs, boots, and coils did nothing. Back to square one.
Video has been made public. Sorry about that |
Check pressure at the fuel rail. Almost seems to me like it isn't getting any fuel.
|
Thanks, I will look into that tomorrow. Unfortunately I don't have a fuel pressure gauge and I won't be able to make it out tonight
|
with a cloth under it, just push the valve real quick and if fuel comes out with any pressure then it isn't fuel pump and I would then check the fuel regulator. My three best ideas of what it is without being at the car are fuel pump, fuel filter, and fuel pressure regulator or a combination from the list.

^I am in agreement. Looks like you knocked out the spark being an issue. If its not fuel than you might be looking at big things. Loss of compression inside the motor or something, who knows. Start with the fuel stuff, sounds similar to when my pump went out, and if you replace that, replace the filter with it.
Also, depending on how quickly you need it, rockauto has much better priced pumps than local stores. They ripped me off good cause my alero is my dd. |
Gotcha. I did just put a fuel pump in about a year and a half ago, so I don't think it's that. I'll check pressure right now and see what I get.
Thanks for the replies |
Is the valve under the plastic intake cover? The one right above the throttle body?
|
UPDATE: couldn't find the valve, but I sprayed a little ether in the air intake and no dice. Still doing the same thing. I also checked compression and all seemed okay there as well. 110, 140, 135, 115.. Is it possible that a major evap leak could cause this? I'll see if I can get my hands on a smoker to test the system
|
Check the fpr it is a likely culprit.
|
Is there anyway to check this apart from replacing it or using a fuel pressure gauge?

Thanks for that! I'll find a hose and do the test now. Looks like it's just two torx screws holding it on the rail. Seems pretty simple to replace.
Thanks again for advice! |

Ran into a slight hiccup... I took off the resonator to get a better view of everything and there was no hose clamp on the bottom fitting. To make it worse, there was a bunch of gunk built up in there. Obviously this isn't good, but could it be the cause of my problems?
|
It's ice! I guess moisture got in there since there was no hose clamp (not sure who did work on this car before I owned it :glare:), collected, and froze. I'm thinking this has to be the cause. Still planning on replacing the fuel pressure regulator.
EDIT: Is that a coolant hose by any chance? It's orange, like coolant, so I'm wondering if it's possible that it got so cold here that it froze even the antifreeze? It's been in the negatives (-15 to -20) here lately. |
That, and the places it leads to, is not a good area to have moisture in. Let alone, THAT much. You may have to dig deeper.
|
I'm looking into it now... It looks like the hose pictured above leads to a box (not sure what it is) on the side of the engine. Another hose comes out of that and leads to what I think is where the timing chain is (where the oil cap is). That hose feels completely solid abd full of ice... I can only imagine this is really bad :(... I might have to look into scraping this thing and getting new car I guess
