Thanks for you friends helping me with this snag. I thought I would re-post part of the problem but please chime in if you can!

It's been suggested to blow out my lines and connect to a portable gas tank to see if my no start problem is due to bad gas in my tank. I've cleaned the V sensor, changed plugs, static checked the fuel pump and injectors, volt check. The motor turns over very well but only runs for 3 seconds if that and not every time. I want to connect my portable tank with known clean gas since I have used stabil and seafoam every year for 11 years and I'm hoping that was my mistake.

So, how do I flush out the lines on the motor to connect to the portable tank?
Thanks,

Not sure how to 'blow out' the lines, but using Seafoam is a No No, as you now know.

If it was me, I'd be opening clamps and draining as much fuel as I could from 'everywhere'.  Re-connect them, and then pump her full of fresh fuel, as much as I could with the bulb.  Actually, get the fuel up past the bulb before connecting, so not to get extra air in the motor.

An Injector 'leakdown test' may be in order, too?  That bad fuel may have done bad things to them also?  Sorry for more questions than answers...

Best!

Phil

Only thing keeping fuel from mixing with coolant waters in my E-TEC's VST is a small sealing o'ring.   Hence not sure blowing out a fuel line is a good remedial service practice?

Phil,
There are a lot of things I've learned not to do! (Insert foul language...)
A guy at the store said to just disconnect the fuel line and let it run dry like winterizing. Don't think that will work for me because it won't start. Maybe I'll disconnect as many lines as I know how like you say and let it drain. On a sad note I'm hoping the seafoam and stabil I've been putting in for 11 years and not using all the fuel in the tank with a few hours a year is the problem.

I think Seafoam is the culprit here.  The Stabil should be OK, as I use their 360 Marine now.  I wouldn't just let it run dry either.

Good luck!

Phil

Gsw, wouldn't recommend using compressed air to blow out fuel system, bad things could happen to the injectors and the seals that are in the system.                                                                              I flushed mine out this spring here's how I did is
get some clean rags preferably white as you can see the old gas better, purchased ahead of this was new fuel filters and VST return filter (not necessary as you can clean your old one)  and clear line to fit where the present gas lines are and a ketch pan I used my oil drain pan also fresh gas (2 gals)
    First remove primary filter and replace it with new one then remove the inlet hose off the primary filter and place a dummy there and place the other end in the fresh gas can. then ( my motor has an in line filter under the cowling) remove the outlet line off the under cowling filter and place another dummy line there and run it to the ketch pan start pumping the primer bulb until clean gas come out. then replace old filter and remove dummy line reconnect the under cowl filter.                                 If you want  to flush out the VST remove the return line   ( Caution   This tank is all plastic and has known to break and is very expensive to replace!!!) and remove the VST return filter and clean it. place a dummy line over the return nipple and pump some fresh gas into the system with the primer bulb. I took it a step further and pinched off the dummy line with a small c-clamp then pumped some more gas into the VST then with help of another person held the return line close to the ketch pan had them turn the key to the on position (Do not start the engine) this should flush the fuel rail out be careful that part of the system could produce as mush as 30psi.  use all safety precautions rubber gloves safety glasses ect. then replace the clean VST filter and lines to original places and check for leaks...
    I'm by no means an E-tec teck  just a back yard guy that learns as he goes, If you Mods have things to add please chime in as I'm also open to learn new things
     Also when you open a line remember there could be pressure on that line that is were the rags come in.                              
      Sorry I was so long winded just trying to be through...

Rideoutr,
Thank you for your thoroughness! I'm a newbie but I can do just about anything with good direction. I know what you are talking about. I already cleaned VST filter and what a hideous place to put the dar thing! I'll give your method a try on Monday because like Phil said, it's probably that seafoam I was talked into putting in. I've never used premium gas either, something I was just told I should do.

Thanks for the tip!

I got it running by using an external tank. Now it sounds like a helicopter in a Landing zone. I let it run for a bit in hopes it would improve. It doesn't just shut off and it starts up right away. Solve one problem and its on to the next! Looks like I'll have to hook up the software.
