fuel shutoff solenoid causes cold start issues?

[jcolvin]

Brainstorming other things that could be causing cold start issues, could this be a fuel cutoff solenoid problem? If the solenoid is sticking or functioning intermittently this could cause exactly these hard-start problems, couldn't it?????

Could be.

Could be.

of course it could be. could be many things. other than posting pictures (you should be posting it in the FAQ section instead), you're not doing the OP any help Mr. Advertiser. If you don't have anything to contribute, don't post

jcolvin, aside from your IP seal being done soon, if that does not resolve it, check the resistance at the glowplugs and solenoid (not voltage). If it's dropping, you may have a ground issue or corroded (internally) wire along the circuit. I mentioned this in the other thread that RSI messed up as well. Not sure if you caught it in there.

The simple question asked by the OP was could it cause hard starting if faulty. RSI gave a simple answer which is correct, and gave a picture of what it looks like which may be helpful to the OP if he is not sure what to look for. It would be nice if Jesse would quit with the personal attacks. I'm tired of it, and I think others are to. If you disagree with Stevens advice, say so, but please keep your personal junk out of it.

Thank you

Well, I am sick and tired of Mr. Advertiser aka Rising Sun Imports posting junk (mostly with pictures). What kind of answer was that? Yes, it could be. How valuable this answer is? How this part in question looks like is irrelevant. Jfarsang always provides technical solutions or troubleshooting steps unlike RSI who jumps into each post with images of parts he sells de-railing literally every single post. So what? The Administration pretends that nothing is wrong and the mess continues to build up. This is not jfarsang who starts the fight but rather RSI's technical ignorance plus agressive and sneaky marketing tactics muliplied by the administrative blessing that sparks and fuels this conflict.
Are we on he usual track again?

if your cold start problems are consistent with every start, but it does start and run, then no way is it your fuel shut off solenoid. if its cutting out intermittently while driving, but the dash lights etc all stay on, then cut in again, then it "could be" your FSOS

You guys are starting to annoy me, it is starting to resemble a "strata corporation" in here. If you don't like what you read...turn your computer off for a while. Every aspect of discussion does NOT need to be guided along by two or three people!!

No. It is not the problem in your case.

I'm scheduled for a pump-seal change-out this week

I would wait until you get the IP seal replaced and then report. Hunting on the fuel delivery system/FSOS is a waste of your time until the IP seal is done and as you said it runs fine when warm and on normal warm days it fires right up. This is not the fuel shutoff solenoid.

Save your money and ignore Rising Sun's advice that it "may" be your problem. It most surely is not your problem.

Posted above is an alternative electrical area that may not have been explored with regards to a solution to your problem.

RSI gave a simple answer which is correct

Rising Sun's answer is NOT correct. You should know better. Brad nailed it on the head.

With regards to pictures, delica.ca has a FAQ and area where pictures/part numbers and manuals are posted. Posting an individual image in a thread like this will not get to 99% of the members down the road as this thread will be buried. It does garner the attention RSI is getting. He's your top poster.

jcolvin, aside from your IP seal being done soon, if that does not resolve it, check the resistance at the glowplugs and solenoid (not voltage). If it's dropping, you may have a ground issue or corroded (internally) wire along the circuit. I mentioned this in the other thread that RSI messed up as well. Not sure if you caught it in there.

All new over-gauge wires with soldered connections, relay hooked straight to battery +ve, extra ground strap hooked straight to battery -ve, bus bar polished, brand new relay. I have systematically eliminated any possible issue with the glow circuit. Trouble is that it is an intermittent issue. After sitting in the cold for days it will fire right up, then it can sit for 6 hours and cough and sputter and pour out clouds of smoke. If a fuel cut solenoid got sticky it could conceivably cause such issues but as you said, i might as well wait until the pump seal has been switched out before looking further; although if i was going to change the fuel cut solenoid i might as well do it while the pump is out.

[jessef]

if you are experiencing cut out's in power/throttle while driving or while at idle, then you fuel shutoff solenoid is suspect.

if you are only experiencing intermittent rough starting, then your fuel shutoff solenoid is not the issue.

The FSOS is very simple to diagnose. In your case from what you've said in the other posts, it is not the culprit.

[MardyDelica]

well, will chip in to this.
were here to discuss not any parts issue.
first nobody want to debate with steven at RSI,its useless. waste of time.
as i mention before he should be more open to the topic not just post the parts.
as we all experience this problem on cold start.
that solenoid could also be a factor.
but you have to do the simple one that it really needs attention before buying all this part
i agree sometime we need to guess trial and error.
but i would suggest do the first thing first front shaft seal injection replace, rebuild or clean, glow plug, relay
then go further.

I concur that this issue is not to sell parts but to help out another JDM owner that has issues. What we should do is diagnose his problem, I have to agree it should not be the FSOS, it is possibly the IP Seal but it should be bypassing the seal when cold and "shrunk/hard" not when it is warm and the seal is providing max potential. If it is intermittent them I would have to say that it is electrical. Adding grounding straps will not cure the problem but mask the underlying issue. First is your Glow Plug timer/relay working properly? Temp switch that plays a part in this is it working properly. I installed a glow plug light on the dash of my Pajero to let me know when the glowplugs were on instead of listening for the "click". This has been invaluable to myself and others driving my truck. This will also let you know if the gp's are on or off. If they are failing to stay on it will give you the hard start and cause smoke. If they are staying on then check your gp's. Pull each one out and test them individually. With gloves on and a couple test leads they should get white hot within 5-7 seconds, if they only get orange or bright red then this is more than likely your problem. If they get white hot then its back to connections, ie the gp rail, connections from relay to rail, or connections from timer assy to relays. The only solution is taking away the variables one at a time.

Pump seal was changed out and so far the issue has not re-appeared. Looks like it may have been slain finally!

[Artacoma]

I like pictures related to the post or not, for us less mechanically inclined and out of an area close to a JDM parts supplier It's great to see various parts labelled . When I'm futsing about under the hood and moving stuff to get at that rattling wrench the last mechanic left in there, it's nice to have a bit of an idea what the bits are.
