Re: 2004 s40 1.9 hard start/wont start

It’s been a while since I posted about this car. It still has same issues, but have learned some things, and made some interesting observations. This gets a bit wordy, but bear with me, please. First off, I have noticed that it does use coolant, and there are no leaks that I can see. So I had a leak...

Re: 2004 s40 1.9 hard start/wont start

Agreed, regarding the likelyhood of the fpr installation causing the trouble. I will say, however, it started today with a vigor. Another observation, is the MPG "computer" on the dash. It shows a very high fuel mileage, like 45 mpg or more when cruising, and 34 as the average. Shows 15 or more when...

Re: 2004 s40 1.9 hard start/wont start

It seems im still battling the hard start issue. I think i have it narrowed down to a rich fuel mixture, or flooding. When i change the spark plugs, it starts perfectly for a few days. After that, it begins to start hard, misfiring and sputtering to life. Eventually, after 10 days or two weeks, it w...

Re: 2004 s40 1.9 hard start/wont start

The reason i ask, as you may have guessed, is so i can rule out sources of coolant in the combustion chamber. I still hope that the coolant is residual, from the previous turbo failure. If the turbo is, in fact, "coolant cooled", the there is the possibility that the new turbo was improperly install...

Re: 2004 s40 1.9 hard start/wont start

After thinking on the latest developments, i have a question. How does the intercooler on the s40 work in regard to interaction with the engine coolant. Is there any opportunity for a damaged intercooler to have coolant enter the turbo charged air, therby entering the combustuon chamber? Or, is the ...

Re: 2004 s40 1.9 hard start/wont start

It started good for a few days, then slowly became more difficult. Now today it started a bit rough, and i drove it a few miles. I then parked it at home for a couple hours, went out to use it again, and it wouldnt start. I pulled two of the plugs, and they look wet from coolant. Not a good sign. Se...

Re: cranks but no start

Did this car run before cleaning the Idle Air Control Valve?

Re: 2004 s40 1.9 hard start/wont start

I have been driving it since last post, and it has started fine so far. I think (hope) what was going on was due to the failed turbo two owners ago. Heres my hypothesis. Owner #1 had turbo failure, and had turbo replaced. Owner #1 sells car shortly after this to owner #2. Owner #2 drives car for 6 m...

Re: 2004 s40 1.9 hard start/wont start

I hope it clears up. The PO said he owned the car for about 1.5 years, and had this hard start/no start issue for a year before he decided to sell. He claimed he changed the timing belt, and coil packs in attempt to fix it, and only put 2000 or so miles on because of its issues. He said the turbo wa...

Re: 2004 s40 1.9 hard start/wont start

Started it this morning and drove it to work. It started easily, ran a little rough for 5-10 seconds, and cleared up after that. I drove it 30 miles into work, shut it off. No issues, no smoke. Smoke in earlier post must have been cleaner i used for IACV & throttle body. After about 1.5 hrs of car s...

Re: 2004 s40 1.9 hard start/wont start

Just now checked compression. 1. 180 2. 178 3. 183 4. 179 Put new spark plugs in, and it started very hard, ran rough and "weak" (for lack of a better word) for 15 seconds or so, then smoothed out and ran great. No smoke. Drove it for 15 miles at highway speeds. Shut it off, and started it warm, fir...

Re: 2004 s40 1.9 hard start/wont start

Tonight i tried to start it again, no go. I pulled the spark plugs. Plugs are black, wet, sooty. After wiping off, they are grey. I shined a light down into the cyllinder, and the top of the piston was wet looking. The oil on the dipstick, and under the oil cap is normal, not milky looking. I will d...

Re: 2004 s40 1.9 hard start/wont start

Timing marks are good. Last night I took of the Idle Air Control Valve and cleaned it, and also cleaned inside the ports that the IACV bolts onto. Cleaned inside throttle body as best i could , given its hard-to-spray-into location. Started it up and drove it. It poured white smoke (with slight blue...

Re: 2004 s40 1.9 hard start/wont start

I thought 80,000 seemed awful low for turbo life. But people seem to have no problem putting new timing belt and head gaskets in Subarus every 100,000 miles. I will check cam timing marks. I still wonder if the position sensor could fail intermittently, seeing that my problem isnt always happening.

Re: 2004 s40 1.9 hard start/wont start

Tested fuel pressure today, and it reads 45psi. PO told me turbo was changed by the owner before him. I assumed it failed. I have read that the turbos on these last 80,000-100,000. Today, it started with no trouble. PO had same experience: start very hard sometimes, start right up and run perfect ot...

Re: 2004 s40 1.9 hard start/wont start

It actualy runs perfect once its started. The prblem is it doesnt start easily. Takes a very long time of cranking with the throttle pressed/pumped, nearly draining a brand new battery. Now yesterday i couldnt start it at all. Just sputtered and popped while i cranked it.

2004 s40 1.9 hard start/wont start

I just picked up a 2004 s40 with 83,000 miles that had a very hard start issue. If i hold the throttle down and pump it, It would pop and sputter for a long time while cranking, and then finally run on its own. I have had it for less than a week now, and now it wont start at all. Just pops and sputt...
