Intermitent issue

[billybobby]

My truck is having issue's. It started missing bad at high RPM only when the tires are lighting fires. If I hammer it on a 15 mph roll it ran fine. I came out to start it the other day and it would start run for a few seconds then die the second I gave her gas. I came back out an hour later and tried it again it ran fine? I drove over to my buddies and shut it down it did the same thing this time it fired up and ran normal after about 15 tries. It is not setting any codes I couldn't get it to miss unless the tires were spinning. Help please Last time I had a issue I took it to three different shops. They all jacked parts at it and charged me a ton of money before I finally asked some questions on here and fixed it myself.

fuel pump is halfway out the door, most likely

That is what I was thinking as well. It was replaced about two years ago the gas gauge started acting up right about the same time the truck started having issue's.

fuel filter or possible MAF

The pump took a dump. I replaced it with a GSS340 walbro. The truck fired up and ran great for two days. It did the same thing today ran out of fuel at higher rpm and now won't start? Any suggestions on why my truck is trashing fuel pumps? Thanks

Maybe you got a bad pump it happens. Also not sure but is this a pump that you put in your factory canister? If so I would take a close look at that connector they were prone causing problems. They make a updated pigtail that I like to solder on, but connectors can corrode so if you have a updated connector that is put on with but connectors I would look there too. Don't forget the relay, if there is a problem with your system its do to a voltage drop caused by a bad connection.

It is the one you drop in the canister I got the kit from Nelson. I also used there new connector. I will check the relay today. Could the relay cause the pump to go bad? I installed it Saturday I used solder and heat shrink for the new connector. If it was the relay why would it work at all just by installing a new pump?

Did you check your tank for contaminants while you had the pump out? Have you changed the inline filter?

[billybobby]

I did replace the filter. Contaminents? It wasn't dirty or anything like that.
