Chevrolet Repair: chevy truck wont start, chevy truck, test light

Question
I have a 1990 k2500 350 chevy truck, No fuel thru injectors. I have fuel getting to the the throttle body. I had to pour fuel into tbi to get vehicle moved so I know it's not ignition problem. I don't have the tools to check fuel pressure, any help would be appreciated.  Thanks

Answer
Hi Ron... low fuel pressure will do that, also no inj pulse could also be a problem... you need to check pressure first. unplug inj and use test lighy in the plug... turn engine over and test light should flash for inj pulse... if it doesn't check ign module....hope this helps
