scratching my head on this one.. 1991 kodiak no start

I posted the files in the linked thread, which I personally verified before posting them.

I'm curious what the Noid light testing for the injector wiring revealed?

i am getting no pulse to the injectors, but i do have spark. reckon it might be an offset issue? this is about to drive me crazy..LOL!

no it can't be an offset issue

ok so i managed to get pulse to the injectors, but no fuel. fuel pump is running, upon further inspection i found the fuel had turned to some milky color.
keep in mind this isnt too old of fuel (6months) so thats weird. i am now flushing the tank as we speak, and im going to fush the fuel lines.
i managed to get it to bust off by means of pouring fuel in the throttle body, but it still has the flashing service engine soon light.
maybe im on the right path...

When an engine briefly runs after pouring fuel into the throttle body indicates a fuel problem.

Possibly the rapid flashing check engine light is bad chip.

I favor troubleshooting the rapid flashing of the check engine light first, by replacing the current chip with a known good chip.

the original chip is toast, im using 27FS512 chips (brand new) with the bin you uploaded. im wondering is im missing something, or if i dont have something just right when i burn the chip.

As far as i know, i have the offsets set right. I'm using BoostedNW chip burning software and Tuner RT to verify everything is right (possibly).
I've become fairly familiar with this software from tuning and playing with my '88 Trans-am Gta, i know it's a different ECM but shouldn't it be the same as far as tuning?


I really do appreciate ya'll taking the time to assist me throught this!

ECM 16147525 Uses a 4K chip, 24 pin. Is this original computer part number and chip for your Topkick?

The 27SF512 chip is a 64K chip, 28 pin. What chip adapter 24 pin to 28 pin is being used?

Possibly the chip is installed backwards?

current ECM# 19186079, which i was told was an updated replacement for the 16147525. when purchased that was all i could find in stock.
The adapter i am using is the solder in GM2 adapter ( replacement of the Moates G2 i used in the past) from boosted NW.
Chip is installed in correct orientation because if installed backwards it will kill the chip.
