Well it isn't 180 out so my nuts are safe! I guess I will go swap out some injectors soon.

[hoogiesngrinderz]

Swapped in the 19# injectors that came out of my running 305. The f*#cker still wont fire without ether...

Even though all 8 injectors measured 16 ohm, I found that 4 of the 8 didn't even fire when I tested them on the bench!

[hoogiesngrinderz]

It was holding pressure better than the other injectors, but now it isn't holding any pressure. Drops right to zero when the pump shuts off. I'm about to stuff a rag in the gas tank....

[TylerT/AZ28]

peculiar. ecm maybe?

[Gregs_gsxr]

what about the cap and rotor ? getting enough juice to spark ?

[hoogiesngrinderz]

I've swapped ECMs (both worked in the Camaro)
I do have spark
I took apart the FPR, didn't notice anything unusual but it holds pressure now
I manually fired each bank then cranked it...sputtered for a split second.

I'm going to go through the grounds. I don't think the injectors are getting a full 12v to fire with the ECM

Injectors ground to fire in case you didn't know. Put a testlight on them to see if they flicker.

[hoogiesngrinderz]

yup, found that out a while back

I put a noid light on the ECM (clip to +12v, probed the pin with the black/green stripe and black/purple stripe) and it flashes during crank. I just can't tell if the injectors are getting enough voltage differential to fire. The grounds on the passenger side head were a little loose, I checked the ones on the driver side. No change.

One thing I didn't mention is that I don't have my oil pressure switch plugged in right now. The current headers don't allow me to do that, I'm going to plumb a 90 or 45 degree fitting to get the sensor closer to the block

[hoogiesngrinderz]

THE ***** IS ALIVE!!!!!!

Another injector swap, plumbed the oil pressure switch with a male/male adapter and a t fitting, yanked all the IP connector pins and went with the basics (will replace one by one), pumped the fuel out of the tank and added fresh gas, a HEALTHY shot of Carb/TB cleaner, and VIOLA!

Oh this will not do where is the vid to back up said posting of moving motor........

[hoogiesngrinderz]

I still need to swap the crank pulley, press on the power steering pulley, swap the TV cable for the longer TPI one, swap headers, run coolant lines, add coolant, and set the timing.

I was hungry so I whipped up a homemade pizza. Do I need to take video of that, too?

[TylerT/AZ28]

yes you do, video of pizza and running truck

sooooooo, your saying we'll see a vid sometime tonight riiiiiight?

[hoogiesngrinderz]

bahahaha I fell asleep after gorging on the za. But, I will go take a video for you impatient fellas.
