Tom757,

There's a number of start-up troubleshooting hints here:

Lance.

No injector opening no gas no go , but really pretty lights and the computer says it is firing.

Now that you have assembled, tested, and installed your MegaSquirt, you need to get your engine started and tuned.

This is the first line from the site you sent me to. The engine wants to go, but no gas no go

Tom757,

Yes, and the link I posted gives several reasons why you might no be getting fuel, from a reversed fuel pressure regulator, to no power to the fuel pump while cranking, to being in flood clear mode.

So let us know on each count which works or doesn't work, and what else you have looked into and what you have found.

if i short to ground the injector fires, but not tru the ms unit bad transistor?

this posting was viewed 721 times and no real help. What can I say maybe it is like the man on the moon conspiricy maybe Mega Squirt works, but not for me.
I might keep working with it , but I doubt it. thanks

The forum etiquette says, "11) Not following advice. If you have started a thread, and other users have repsponded asking you to perform certain checks or supply specific information, it is likely you won't get any more responses from them until you do this. Of course, ask for clarification if you don't know how to do the tests, aren't sure about what is needed, or the test itself doesn't make sense to you. But if you simply ignore it, you'll likely find that user won't respond with any enthusiasm to your thread until you do what's required. "

I asked you for the result in the links I posted, you have not responded. You might want to check this post: http://www.msefi.com/viewtopic.php?t=16456

been there done that doesn't work . everything appears to be good except NO GAS FLOW OUT OF THE INJECTOR WITH OUT PHYSICALLY PUTTING THE NEGIATIVE WIRE TO THE BODY OF THE CAR OR ENGINE otherwise a great light show
There is something inherently wrong with my unit i believe, I did not make it therefore I am at a loss.

everything appears to be good except...

Tom757,

Telling us that is as good as telling us nothing. You need to tell us specifically for each step what you found. For example, does the fuel pump power up? Do the injectors have 12 Volts while cranking? Does MegaSquirt? Are you in flood clear? Can you post a datalog that shows you are not in flood clear? Do you have fuel pressure at the injectors, or is the fuel pressure regulator a problem? Is the code laoded and properly configuredd? Do you have a stim, and what do the INJ LEDs show, etc., etc., etc., etc..

INJECTOR LIGHT FLASHES ON CRANKING
THE ONE NEXT TO IT LOOKS LIKE A SPAZ FIRING AT SOME UNKNOWN BEAT...
Car to look at the unit and fix it? I could send it to you for a project and pay something for your trouble
