my truck had been mis fireing randomely so a friend suggested i pour some seafoam into the throttle. well i did 9less than an ounce , and the truck starts then rpms to 500 then cuts off. it would stay on to 1-1.5k with help of the gas pedal. let it sit for 4 hours and same thing.

Any ideas or suggestions?

 

to make matters worse, now the fuel pump will not engage when the key is turn to the on position. my fuese chart under the hood is not correct because i replaced it a while back.

 

grab a test light and start testing, or pull one by one.

 

well i replaced the fuel pump relay and a few of the 10a fuses under the hood and the truck starts and dies down after a few seconds. i'll keep trying to get it to run. i had it jumped to another battery to make sure there was enough juice. i can hear the fuel pump engage now at least.

 

****Problem resolved**** by replacing the fuel pump relay and a blown 10a fuse under the hood along with clearing the codes. until i cleared the ses light with a hand held it would not stay on.
