Accelerator delay

[DeadCrow]

Hello folks, great to be here, I'm kind of new to the site. I am working on a 1984 M1009. I love the truck, I've had it for 20 years with not much drive time in that span unfortunately. I am currently experiencing an issue where, when I press the accelerator, it takes about 5 seconds to kick in. It's pretty consistent. This has been happening for a few weeks, but like I said, it's unfortunately not driven much. I am wondering if anyone has seen something like this.

Thanks in advance for any thoughts!

Had a similar problem in my 5 ton, turned out to be the filter assembly, couldn't hold prime. Replaced my o-rings, cleaned the baring surfaces and replaced the filter solved the problem. Another issue I had was a rotten fuel pickup tube in the tank. Not sure if your rigs have the same issue.

hmm, I just had the tank replaced last year. Hopefully nothing wrong there. I'll check out the O rings ASAP.

Does this happen all the time, or just when engine is cold? Cold meaning first start up of the day. What happens if you start it in the AM and just let it sit and run? I'm thinking lift pump or sorry to say the IP.

Thank you for the reply, I'll run it a while and see. Hopefully maybe it just a cold issue. Its been pretty chilly. I will check and post back.

Thanks again!
