Re: Fire, then no fire

I have never had this type of symptom.

It does not sound like a typical fuel pump problem. But, to be sure, I would check the fuel pressure at the rail with a gauge. Fuel squirting out of the schrader valve may not indicate whether there is enough pressure.

If you have good pressure at the rail, what about the regulator?

Can there be some glitch that is shutting down the injectors after the engine fires up?

What about the ignition module? I have never replaced mine and seem to remember reading that aftermarket modules are trouble-prone. Maybe?

But, I would so what you are doing: posting the question and seeing if anyone has a good suggestion! Good luck!
