you got me. the truck just died at the gas station one night, wouldn't start back up.

it seemed to be a fuel issue, so i checked the fuel pump and couldn't hear it click on so i replaced the pump. now it's working fine, gas is getting all the way up front but it's not starting still. so we pulled it apart and cleaned the injectors, and now it's dumping fuel. when i turn the ignition. it didn't seem like the gasket sealed right so we redid the gasket so i'll try it again tmorrow when there's light

no when bill put the injectors back in he missed the o rings. i just bought the gasket kit and we replaced those so no leak. it starts up, and dies.

it was leaking around the injectors, so the fuel is at least getting there, just past that i can't figure out what to check test or replace. and i'm trying to have a better guess since i'm on a limited budget now to fix it

I am betting on the regulator/Diaphram and the lack of fuel pressure...

if it sits for a few minutes, it starts up normal, then dies out right away. i'm thinking pressure. but i'm an idiot and know nothing i'm just thinking if this were the problem on my bike, it would most likely be this:\


friend of mine thinks it's the injectors, which are like $80 a piece, i had a ton of stuff for my 79 that was still brand new so i returned it to get credit to get the injectors, and one location had one, another location had another. so i grabbed one, we drove to the other one, and it's the wrong injector in the right box. so now i have to wait for one to come in.

i still think it's pressure related. i never checked the fuel pressure cuz i didn't have the gauge to do so. i mean it's getting gas up to the tbi, and it seems to stop at the injectors. when we overlooked the missing o rings at the top it was spilling down in there so it's getting fuel it's just not doing anything past that point.

Pinching the return hose will increase the fuel pressure on the supply side so if you have a bad regulator bleeding off the pressure this should negate it...  Or if you have a leak, this will expose it.

during troubleshooting today, hooked up a 9volt batt to the injectors.

they sprayed just fine, truck started up. so my injectors aren't getting power from.... __________?

The ECM triggers the Injectors to fire.  Do you have anything disconnected?  Any broken/frayed wires?.  The injectors are tied into the fuel pump and oil pressure switch, are you gettting oil pressure?  Is it connected?  The only other thing I could thing of it the ignition module.
