Hello All
I picked up a used blueline thermal wave 2 with a Vortech engine, I bought it as is hoping I could spend a few hundred bucks to get it started. But after spending money on mechanics and parts back in square 1, The machine runs for five seconds then shuts down, is there anyone out there that might have a clue or can help me out ?
I operate out of central California, unfortunately nobody has yet been able to figure it out!
Thank you All.

Machines only do what they are told to. Bypass every safety feature one by one... Eventually you will find out if it is a safety feature that is causing it or a mechanical problem is. You are going to have to invest either money or time to fix it. Start with the electrical schematic.

Some blueline thermal waves are plagued with overheat problems. I remember reading a lot about that issue.

I dont remember the exact model everyone was talking about but basically the machine just isnt able to disperse the heat well enough so it goes into protection and shuts down.


I think one guy stripped it down to the basics and installed a big exhaust fan in his truck to help but most just moved onto a different machine

Take off all the extra hx exhausts.....

Put a standard muffler designed by the engine company.......

If it starts then get rid of all hx and get fuel,heater.....
Thats what i did years ago....

Call judson...he does this as a standard procedure...
Also,he has a branch out in california....

Firstly I do appreciate your response, I talked with Scott over at sapphire and he suggested undoing the main wire to bypass all kill switches and I did.
The “mechanic” who claimed to be a specialist
Had the van for 2 weeks couldn’t figure it out!
I changed the MAF sensor but No go,,
So,, I’m trying to see if anyone out there ever encountered a similar issue?
Thanks,,

when I crank it runs for 4-5 seconds in idle then it dies, I can do they over

When I fire it up it runs on idle only for 4 secs and then it shuts off. It does that over and over,,

ya doesnt sound like overheating if its only 5 seconds.

is it cutting off abruptly or chugging and dying? immediate it could be a wiring problem, chugging and dying prob more like fuel starvation, bad air/fuel mixture etc

do you know if the mechanic checked the fuel pump/fuel solenoid?

you might just need to find a better small engine mechanic that can figure it out

Your only other alternative if that doesnt work....
Is strip it all out...accept the engine......all sensors...hx......
And install fuel heat.......

Its a big step as i went through 2-3 hx systems and decided to go that route 12 years ago....
Never regreted it..and will never go back to hx......

These guys at judson have specialized at doing this.....

I know this is awfully simple, but you waste tank float isn't up or defective is it?

It can't be a kill switch because it wouldn't crank. Sounds like a fuel delivery issue. Check fuel pump and filters.

My bet would be fuel pump solenoid because it's somehow getting enough to start but then starves out
I pulled out the hose that

thank you for your help, but I’m not ready to take that drastic of action at this moment yet!
I like the idea of HE, it’s safer and cleaner but not as Hot, that’s for sure,,

I put a bucket, disconnected the fuel line and dropped it in there, then cranked it and I saw the bucket filling up just enough to rule that out,,
Thanks for your help!

Pump is good filter is new but not too confident about the fuel pressure regulator.
Thank you for your help,,

That sounds like a good plan and what I’ve already been doing,, I know this old small engine mechanic who is willing to look into it !
Thanks for your help,,

Hi Jim, so,, here’s what happened I pulled out the in-line hose to the Throttlebody/MAF sensor
Opened the butterfly wing inside there just a little
and jammed a thin piece of toothpick to keep the wing open, then put the hose back on there, now I can run it in low speed for a long time without it shutting down but it runs super rich and h2o pump gauge reads 00! malfunctioning all the way.
I’m under impression something is preventing get to run optimally !
Thanks ,,

Make sure it doesn’t suck up that toothpick.

If I remember correctly those vortec engines and that unit had issues with the o2 sensor failing. Causing running issues. That sensor is located just after the exhause manafold. Sometimes the exhaust donut from the manafold to the exhaust pipe would fail and burn up the wiring to the o2 sensor. This causing a rich issue and the engine not running right. Try unplugging the sensor and running the unit to see if that changes anything. If it runns better then that’s the issue.

Does anyone out there have an extra Ecu for my blueline TWII vortec #38900438B ? That seems to be the problem. I borrowed one from another machine to see if that fixes the malfunction, and there it was, the answer to my problem! Thanks,,
