What have you done to your Festiva today!?

Or just take a rubber hose put it on the top of the injector fill it with gas then put an air hose in the end wire a positive and negative to the injector and touch a battery to it and you can see it shoot fuel. Try all the injectors make sure they work.

IIRC Matt D does service our Mazda injectors, cleans and balances them. I Think somewhere it says $80 for this service.

[Aaronbrook37]

Good stuff... keep us posted with how it goes!

[200KGPGTP]

I'll just try cleaning these then

[Aaronbrook37]

Oh definitely. I got showered with fuel last night as a testament to that.

Also, injectors ARE getting pulsed, so it's gotta be the injectors themselves. I think I'll take them out and soak them in diesel or something.

Are B3 injectors the same?

Festivas are 120cc and I believe the 323's are 130cc.

Gotcha.
Are you sure fuel pump is working and building pressure?

[200KGPGTP]

Intake is an awful temporary setup. But it's secure and sealed... To start it with starter fluid, I removed the pcv breather hose, sprayed some in, replaced hose, then went and cranked. It sputtered to life great but obviously didn't last

[Oren09]

How are you spraying in the starting fluid?
You do have the intake piping and VAF connected securely, correct?
Just check simple stuff

[Aaronbrook37]

Oh okay it starts with starter fluid? Yeah take a real good look at those injectors and anything powering them. Sounds like your compression is good enough to at least start the car!

[200KGPGTP]

Dunno about the injectors, it's a 70k mile B6 that has likely been sitting for 5+ years. Excellent condition otherwise though.

I'll do some more troubleshooting tomorrow I suppose.

Roger that. Were these injectors known good before they were installed? It's unlikely they've all clogged up with gunk, but it's hard to say I guess. Rent a compression testing kit from the local auto parts store and get back to us with some numbers if possible. That'll help eliminate a big variable. I don't think I've ever seen a motor with air, spark, fuel, and compression not start.

[200KGPGTP]

Ps, it can run on starter fluid

[200KGPGTP]

What are your injectors doing?
What's your compression dry and wet?
Spark going to all four plugs?
Air filter okay?

Fresh B6 swap didn't start.... Have spark and fuel to the rail, but not past that.......

WAT DO!?
