TBI fuel injector trouble?

[bradshawtech]

I sometimes use a 8 inch long piece of straightened coat hanger, stuck in the #1 spark plug hole. Then turn the engine over with ratchet and socket.
When the coat hanger gets pushed out, and the timing mark is coming around, you know you got #1.
Then, line up the big timing mark with the pointer.
That's it!
Pull the dizzy, and drop it back in, with the rotor pointing at #1 cylinder.
You may have to turn the oil pump rod to align the slot with the dizzy.
Apply spark plug wires.
BAM...DONE!

There’s the chance using the coat hanger method that it’ll be 180 degrees out of time since it could be coming up on the exhaust stroke, I like to put a finger in the spark plug hole as you turn the crank with a socket, when it pushes your finger out of the hole then you’re on the ignition stroke, then line up the timing mark and then line up the rotor pointing at #1.

got the thermal paste from best buy per the link i sent, was hoping that would be the remedy - still no start

 

[Mastiff]

I think the paste would mostly just keep it from frying once running. If it never started with this module, I'd look elsewhere.

Back to basics boys. It'll get you everytime!
Check for spark, check for fuel, check for timing

I use a compression gauge hose in #1 cylinder, front driver side on sbc, and a remote start button, to bump the engine over with my thumb over the hole. when compression pops my thumb off the hose, I then turn the engine with a wrench by hand to line up the timing marks. If no remote start tool a helper can bump the key in the cab. Be sure to unplug power to coil.

Another trick is to line up the crank timing marks at the degree of advance you wish to have as base setting. Then stick the dist with rotor dead center of #1 tower, lock down the clamp. You should be with in a degree or two of desired timing.

Going by 3rd diagram, and your pictures of dist position, I am guessing your to far advanced in spark timing

Also I am not happy with the color of the connector pins to module from pick up coil. if the female part is as lack as the out side this could cause resistance possibly enough to keep the truck from running.

great stuff!!
i'll aim to mimic this angle when i go test for spark in a bit

@Wes Harden @BoondocK5

in thinking about it, i might snag a new distributor pickup coil today. i didnt even notice how black and 'fried' those look
also, i tried adjusting the timing just now, and because of my ghetto oil temperature sensor fitting, i cant get spot on to that mark sent in the image above
lastly, i have a Summit oil pressure sensor arriving in the mail (hopefully today), and i realized its the correct threads of 1/8 female to 1/8 male
the one i put in there was 1/4 male, 1/8 female - i wonder if that is contributing to it

nonetheless, i just had a couple minutes to test for spark. threw my phone in there as i cranked and was able to snag a screenshot from the video
i tested cylinder 1 and cylinder 2 since they are the first and last in the firing order 1-8-4-3-6-5-7-2

i have a yellow/orange spark in both.

should i test the coil or distributor, or try again after i put in the new dist. pickup coil later?

You have spark, so let check fuel. Get a can of starting fluid.
Cosby sauce, as Peg calls it.
I have a can, I only use it cases like this.
Give her a snort, then crank. If she fires great! If not, you got a timing issue.

 

[Wes Harden]

Well you have spark. I suspect it would be a nice lighting blue if had a better ground.
Let work on the timing

@Wes Harden @BoondocK5

i have a timing light that ive used in the past, but i cant use it without the engine running
i'll try the starting fluid to get her going, but if not, how would i set the timing
do the top dead center method mentioned earlier?

 

[Wes Harden]

Timing light is not needed till it is running.
1st we need to know the distributor is clocked correctly and rotor points to #1 tower at Top dead center compression stroke on #1 cyl.

So check with starting fluid then get to top dead center and try firing

We've already been over how to get TDC.
Use what ever method works for you.
I'm 30+ years wrenching on junk, and I still get a dizzy in 180° out once in a while.
So, don't fret, if you "F" it up. It happens!
Do you have a compression tester?
If not, Use my cost hanger trick.

 

[BoondocK5]

The anticipation is killin' me

i don’t, the “stick something in the hole” trick will have to do

Haha

@BoondocK5

We’ll, just tried starter fluid and nothing. It tried to turn over and almost sounded like it had it once or twice but wouldn’t stay on

Wonder if that oil pressure sensor being the wrong size is still the culprit?
I have the new fitting showing up tomorrow now, wouldn’t be able to rotate the distributor even if I wanted since the one I put in is smack next to it

Back to square 1. Think it’s the distributor coil thats fried? Or is the timing that far off
