3.0 3vze #1 not firing?

[uprunner]

Ok so I have a freshly rebuilt 3.0 v6 bored thirty thousandths milled deck milled heads, ported and polished, polished and balanced crank, new fuel injectors, new injector pig tails, and I can't get #1 to fire, it has the same compression as all of the othed cylinders, the wiring is %100. Good and gone through I've tried differnt ecu's changed my maf swapped around fule injectors and I still can't get it to fire it has spark, any ideas I'm at a dead end and 10000 percent stuck. :/ oh and I've put 1500 miles on the motor with no other issues

Bad injector, wiring, valves too tight, bad plug or wire, etc etc.

hey my friend needs a boat anchor for his 30ft CRISS CRAFT,:haha:

That rigs coming along chase sucks ur having that issue atleast it got ya back home from BELFAIR yeaterday ,ull figure it out an learn something at the same time.

Ok let's point out the easy stuff, injectors good, its been tested, has spark to the cylinder, timing must be on or thered be more issues, all three wires from those pigtails on the odd side of the motor blend into one wire positive and negative, so how does the computer single out each injector to fire?

If the valves were to tight how could that effect it?

Loss of compression

batch fire... not sequential... one of the many reasons 3.slows get crappy milage..

 

[uprunner]

Cylinder has the same compression as the other 5 not any lower at all

wow I just learned something. That makes allot more sense now.

Wonder if ther would pep up and get better MPG with sequential injection?

Does the 3.4 wire the injectors like that too?

I'm pretty sure 3.4s have sequential

There is more to is than simply rewiring it.

get an ohm meter and verify continuity at the injector plug to where all the wires come together...

mega squirt would probably do wonders for it... to bad it would be money wasted on polishing a turd.

 

[uprunner]

All of the wiring has been re done abd the ohm metter showed its good, other posibilities?

 

[Damnyankee]

compression good check
spark good check

gotta be a fuel issue.
just because the injector tested good with an ohm meter doesn't mean its good.

Pull that plug and smell if it has gasoline on it. If yes do a compression test......Rather than testing injectors and tracing wires just put a trouble light on it and see if it flashes when running. Rapid flash means it's pulsing.

I'm gonna pull off the timing cover and check all of that for the 5th time, I've tried everything else

 

[Bill]

have you tried a new plug wire and plug?

 

[Flat-Bed_3rd_Gen]

have you tried a new plug wire and plug?

X2!! is the plug fouled out? maybe just no good? is it arcing through the ceramic and through the boot?

What do you expect to find in there?:eeek:
