chevy tbi no spark no start no pulse at injectors 

Ever figure out the problem

This is the problem I'm having. Any luck figuring it out ?

Glad it helped

@Mireles Gio yes sir she did...

Glad it helped!

So did your 87 Squarebody just die on you mine did and I’m thinking about it’s totally the distributor now

​@Frankie Nickels did you get it fixed?

​@@JaboTheMechanic I have a 98 caddy sevelle. If I spray it out gas in throttle body it will run . No pulse signal . Getting gas in the fuel rail . Just no pulse . What could it be ? It's about drove me mad Ty

Old comment but ill answer. Reluctor is bad in distributor. Change the distributor to get pulse back to the ecm to make injectors work.

Check ecm fuse

i can try to get a video of the sound im hearing thats coming from the carb when I have someone turn the key to on position but yes please lmk any details or whatever what could be the problem but the distributor/cap rotor plugs wires fuel filter fuel pump has been replaced so far

You figure it out

You ever figure this out? I'm having the same issue

@@ieatfoodthatisgood ended up taking two distributors and made a good one. used a new cap and button. old one had play in the drive gear and cracks. if they don’t fire they won’t get fuel, also changed the black box beside brake booster (after distributor was changed and did not test before changing black box) it would be easier to buy a new distributor. they come with new icms. but didn’t have the money at the time. let me know how it goes

Thanks man your reply means more than you know. I'm gonna give it a shot

@@ieatfoodthatisgood no problem, been there done that. was very stressed for 3 days. wish i had help back then

I had the same problem. So I put 12 jumper wire to my injectors and they pulsed. If you put gas or spray starting fluid will yours start then ? Mine will . I'm totally stumped 🤔

Getting sparks from distributor

@ghouliesgarage3922 Did you ever figure it out, i had the same problem

It could be your distributor

Did you ever figure it out?

You end up getting it fixed?

Yes you can but check your ecm fuse too

Fuse is good. I tested new distributor like In your video spark is present but still no injector pulse. I'm just about fed up with this truck.

@@robertgarcia2992 Just bought the car, and have the same issue. It gets power, but no impulse, I haven't test any other distributor yet. My serviceman made a button to manually inject fuel when cranking, also I have to spray choke cleaner on every cold start, but it works!

I have this same problem. Did you get yours figured out yet?

@@ghouliesgarage3922did you ever fix the issue?

No

If they are intermittently going out. It could be faulty tbi's

@@JaboTheMechanic I replaced the injectors

You need to make sure that your ecm fuse is good

Why I'm not getting fire to the fuel injection wire to my fuel injection ejection carburetor

Oceanside California

Ignition coil could be bad

@@JaboTheMechanic What if you recently replace the ignition coil? I had a no start no spark situation and it was a bad ignition coil. I replaced it and it worked great for about 5 starts. I let the truck sit for a few days and then back to no spark at the coil. I came across your video, which is great, tested with a different distributor (new out of the box) and have a pulse but no spark. I still have power to the coil as well.

The distributor is bad

Did you try it with a new one. Your distributor controls your tbi as well

@@JaboTheMechanic yes I tried a new one I bought it today

And still no injector pulse. Is your fuel pump priming when you put the key in the on position

@@JaboTheMechanic it is I have fuel coming up to the tbi, I'm going to trace the wire to the ECM I might have a bad wire

Me too on a 93 k1500 350ci

Most likely the ecm is not getting power or ground. When you first turn on the car do you see the tbi spray one time

@@JaboTheMechanic 94 K1500 5.7, no same thing. New pump, filter, ICM. For some reason it seems to not want to start when I park in my driveway on a hill. Worked fine after replacing pump and filter (last time I parked in my driveway about 3 weeks ago, it wouldn't start back up, towed, changed pump,filter) It's a spare truck so first time driving in 3 weeks since replacing pump, filter. The truck was being driven but not by me for several days with no issues. Once I get the truck and park on my driveway overnight, it will not start again. Just changed ICM and still nothing. Any suggestions?
