What have you done to your Festiva today!?

[RhodeStiva]

^x2. try swapping at top of fuel filter and return going in next to the fuel filter.

[Oren09]

Past the regulator?
Do you have the fuel lines hooked up backwards?

[200KGPGTP]

Turns out fuel isn't getting past the regulator.... Can I use a B3 regulator?

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.

[Aaronbrook37]

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.
