    Just want to say I owe you a case of beer! My truck was running fine and just wouldn't start one day. There was no gas to the TBI injectors. Changed fuel filter still no gas. Cleaned grounds you show in your video, IT STARTED RIGHT UP. Thank you again and if you want just send me a message. GREAT HELP and THANK YOU FOR SHARING!

    Ok. I havent checked the relay or grounds. I went ahead and replaced the pump and strainer. Turn over, no start. Pump is running though. No fuel getting to the tbi. 1988 gmc 1500.

    Really appreciate this i have a 88 k1500 5 speed 350 short bed regular cab that my grandparents bought new and i have now owned it for 12 years its my baby and i keep it as clean and nice as i can it just now going on 120000 miles. Me and my wife wer headed back from jay Oklahoma with a trailer on and it just died. Everything stayed on (guages radio lights and so on) but it was basically like i pulled the coil wire off thats how it died. No spitting and sputtering. It had blown a fuse I believe it was a 15 amp fuse that said ecu and I believe thats the module that has the “prime wire” to kick the fuel pump on before the engine has started. Put another fuse in it turned key on it started and died popped another fuse. Then put another fuse in it and as soon as i would turn key on the fuse would pop. So with basically having no other options i put a 30 amp fuse in it and it didnt pop (i know it was stupid but was in the middle of nowhere and about a hour and a half away from home. I was hot and flustered. That worked got it home then put a 15 amp back in it and it didnt pop and hasn’t popped for the past 3 weeks then on my way home from work tonight was going down the road and it did the exact same thing everything stayed on but was like i pulled coil wire so i pushed in the clutch went into neutral and was gonna coast it till it stopped but before the engine quit rotating it busted back off and now has me really scratching my head. Obviously the fuse wasnt popped that time. The fuel pump is original to the truck none of the wiring in or on the truck is hacked up or anything so ima check all the grounds you pointed out. Im a hardcore gearhead just the darn thing got me flustered just because of whos it was and it means the world to me but you have givin me a little more to check out so i sure hope i can find something or i warned it that it was going to become carbureted lol sorry for the rambling and thank you wish me luck

    Replaced all the grounds on my 1989 Chevy K2500. Added a few more. Made a huge difference all around. All the lights are about 50% brighter and everything seems to run better. Great video. Thanks.
