2.2 fails to run.
Hi All. Say, I've got a problem with my 2.2 Legacy. It starts rite up, idles smoothly for a few seconds, then dies. Good spark, good fuel pressure well after it dies. I've checked for vacume leaks, everything seems tite. It was throwing a 49 code (MAF), replaced that, no change other than no codes now. It's really close to continuing to idle, but seems to have a fuel cut when it dies. Not sure what to look for next. Thanks much, Steve.

Sounds like a vac leak, have you checked the line going to the IAC?

Re: 2.2 fails to run.
Yes, I've looked it over closely, don't see any leak points. I was thinkin' to try a little starter fluid around possible areas, during the short idle periods. And, scratchin' my head. Thanks, Steve.

Re: 2.2 fails to run.
Hmm, if fuel pressure looks good, check the fuel filter.

Filter's pretty new, pulled the line, great flow. Thanks.
Re: 2.2 fails to run.
This might be a stretch but I once had a cracked intake at the base where it bolts to the head, but it still ran. Its acting like the MAF isn't reading the proper amount of air.

Re: 2.2 fails to run.
It was throwing a 49 code a week or two ago, so I replaced it with a JY unit the other day. No longer a code, but no change in run time, maybe 10 seconds. Just picked up some starting fluid, thot I'd give it a leak search that way. Thanks guys. S

Re: 2.2 fails to run.
Sounds like a fuel pump... what fuel pressure are you seeing?

Re: 2.2 fails to run.
I've got it set at about 35-40lbs. I seems to me not to be pressure or volume, but more the injectors stop firing. I,ve been meaning to break out the stethoscope and listen to the injectors as it dies. This business of making a livin' seems to keep gettin' in the way. And sadly, the nite crew doesn't get much done any more either. Oh. I also have another ECU I should plug in just for snicks and grins. Thanks

Re: 2.2 fails to run.
Have you tried running it with the MAF not hooked up.
I think it will run and it would rule out the MAF and wiring if it still dies.
