And now this...

Been having an issue lately where machine don't want to run when first started. Idle for a minute then quit. Now it's getting hard to start when does it. Then last night we went out and I was in high gear. Started up mountain so I switched to low range and it would barley go for about 10 seconds. I know air filter needs replaced going to get one today. Is this a fuel pump issue or the air flow sensor? Where is the air flow sensor located so I can clean and has any one ever put Seafoam or that type of product in fuel tank or in engine when changing oil?

I would definitely check the fuel pressure. Mine did much as you describe when I had inadequate pressure.

I “borrowed” a fuel pressure gauge from autozone or oriellys and installed it in line in the line from the tank. I was only getting around 30-35 psi. You should have 50ish to run right. There’s a sock filter at the intake of the pump assembly in the tank and the pump itself that can be replaced.

Also, check your exhaust screen as they can clog. I take mine out occasionally and clean with a brass brush.

Where is exhaust filter located? Im pretty sure i can find the fuel pump. And do you know where air flow sensor is? I'm going to assume its close to the motor. Google told me nothing.

The exhaust screen is accessed by removing the 3 Allen screws which hold the exhaust tip on. Then just pull off the tip and the screen out. Don’t worry about the tip gasket. It’s paper and will likely be trashed. Use hi temp silicone in place of the gasket. There’s even odds that one or more of the nutserts will be rusted and have to be replaced if antiseize was never used. See this thread on adding new ones and I can send you a few if you need them. https://www.commanderforums.org/foru...tip-bolts.html

The fuel pump is in the gas tank. The filter is at to foot of the fuel pump assembly. There a lock ring you tap to loosen to pull the filter out.

The air sensor your referring to is in the plastic intake between the air filter and plenum - on top iirc. Pull the switch panel back and you should see it between there and the filter box.

Thanks for your help. If it's a fuel pump i can get that from a parts store correct? Seen in another thread a E16013 fuel pump is perfect and affordable replacement. But didn't see it on Advance Auto website.

That's the O'rielly's part number for the pump. When I bought one, my oriellys had it in stock. S13006 is the oriellys number for the filter sock, they likewise had it in stock. The sock is $12 at orielly. The pump is $114 - it used to be considerably cheaper.



For another source, JT posted this online link for fuel parts the other day: https://www.highflowfuel.com/ag-1323...-1000-efi.html The pump is $84 here.


Given that Orielly stocked it, it must be a common pump so there are probably other cross references at other local stores. Summit racing has it for $35 https://www.summitracing.com/parts/atx-e8335 which I believe is the same pump.


Here's where the air sensor you mentioned is (#3):







When mine was running like crap, this is a video I made of the low fuel pressure (I had a rusty fuel tank, which was clogging things and I eventually replaced it):

Waiting on neighbor to get home. Almost guarantee he has something for me to test fuel pressure and I will take it from there and let you know. Thanks again for your help.
