    Crank no start 89 5.7 TBI Injector Pulse

    Stuck injectors is what it was. 8 taps on each one and she fired up. After the mouse nest was spit out it runs good. A little boggy when you give it gas at first but that should clean up with time. Thanks for the help guys!

    Crank no start 89 5.7 TBI Injector Pulse

    Thanks for the info, as soon as I get a buddy out there I'll tap them while cranking. Attached is a pic of the ignition relay. At least that's what Rock Auto calls it.

    What is this plug and where does it go

    It is a brown wire, yes. I dug around in that tubing this morning but didn't find the other plug. There is one about 6" up that is also brown but it is plugged into another wire as you can see in my pic..

    What is this plug and where does it go

    Does anyone know what this plug is and where it goes? I've owned the truck for 2 weeks and am troubleshooting a crank no start injector pulse issue. I'm not dumb but I also don't see where this could plug into. 1989 5.7 TBI.

    Crank no start 89 5.7 TBI Injector Pulse

    Sorry for another crank no start thread but I searched for an hour and couldn't find my exact issue so here goes. Bought the truck not running. 1989 C1500 5.7 tbi stepside 5 speed. P\O started to remove tank for new fuel pump but didn't get far. Since tank was half way out and the new pump was...

    98 K2500 Fuel pump - brake pedal issue

    No SES light, but I don't know about any stored codes. I know what you mean by on\off. We even unplugged the brake switch and the symptoms stayed the same. That leads me to believe that the brake switch is probably ok but the wiring going to it maybe the culprit... IDK, am about to give up on...

    98 K2500 Fuel pump - brake pedal issue

    Didn't see all of your message at first. It does it in park and or driving, it doesn't matter. During our troubleshooting\research we had read about voltage issues so we turned on all the lights, blower, anything we could to draw power. It didn't matter it still acts the same. Battery is 2 years...

    98 K2500 Fuel pump - brake pedal issue

    Yes all abs, brake fuses and relays, brake pedal switch, and even the wiring that feeds the tail lights\reverse lights were all unhooked during trouble shooting. The problem never changes no matter what we leave plugged in or not plugged in. Is there anything safety related that could cause...

    98 K2500 Fuel pump - brake pedal issue

    I should've mentioned that we unhooked the vacuum line and plugged it with our thumb. After pressing the brake pedal down it still shut the truck off so we are thinking that the vacuum side of things aren't causing this issue.

    98 K2500 Fuel pump - brake pedal issue

    Recently did a engine swap on a 98 k2500 with the vortec 350 with automatic. Truck came in with a locked up motor so we don't know if this problem existed before hand but owner doesn't recall anything like this. Year of the donor truck was also 98. Truck starts and runs but as soon as you press...
