Tre3 "have suspected the most obvious: a fuel injection problem. But, following this post, it seems a fuel pump problem may be the cause. Two pints of Sea Foam injector cleaner have not helped."

In my 97 i suspected the same thing, but after moving the wire by the fuel pump a little bit it started to turn over right away, its a black wire in front of the fuel pump. I just did it last night and its starting up better then ever now. ( i believe its the relay wire but not completly sure.)

Possible fuel pump problem, too?

My 98 4-cyl TJ, with fresh full ignition tuneup, runs perfectly but always fails to start on first crank. After a 1- or 2-second crank, it will almost always start on the SECOND crank attempt. I have suspected the most obvious: a fuel injection problem. But, following this post, it seems a fuel pump problem may be the cause. Two pints of Sea Foam injector cleaner have not helped.

richupnorth Check out this video on how to drop the tank... http://www.youtube.com/watch?v=0GtgB1sSEmQ

By the way, I thought my fuel module was out last month, but it turned out to be the wiring harness. It split somehow. The outer plastic was holding it together until I touched it and it separated. Dang squirrel!

joe130 I have a complete fuel sending unit (200 miles on it) on eBay right now that is currently going for $10. Just go to ebay and search for jeep wrangler fuel sending unit.
The swap is pretty easy, just a little time consuming. Lots of writeups out there for it.

little4x4 I know but, i work in a shop and i have done "just pumps" before and you say your sending unit is out but there are things like the check valve in the sending unit that go out as well. This is when you got to cycle the key a time or two to buld the fuel pressure back up so you can start the engine and once you get into it if you can not fix the problem with the sending unit and have to get more parts then more time down. I have seen times where the pump only kits the pumps don't last as long so you may have to do the job more than once (cheap aftermarket partsare not as good as OEM most or the time) just my two pennys any way.

True, but buying the parts and rebuilding myself could save a couple hundred bucks. The full assembly is 300+ where the new pump, filter & floater can be purchased for 100 to 150.

So anyone else go the rebuild route on their fuel pumps?

jeff83 I have a perfectly good pump and assembly if you want to buy it off me pretty cheap. It needs the filter but that is all and if your filter is good then this will do it for you PM me for details. The only reason i took it out is because i installed a fuel cell.

Replace Fuel Pump or Fuel Pump/Sending Unit assembly?

Hey all,

My fuel pump on my 4 banger is going out. I know it's the fuel pump just by the way it's acting, I went through 4 fuel pumps last year in my Blazer, and the Jeep is doing the exact same thing.

I've been surfing the net looking for a new fuel pump so I can just replace it myself. What I've been seeing mostly just the actual pump to be replaced in my sending unit, instead of the full fuel pump / sending unit assembly which was the only option in my Blazer.

Getting just the fuel pump is much cheaper then the full assembly. So I figured I'd post here to see if anyone has any experience in replacing just the actual pump? pro's / con's of either would be greatly appreatiated.

I should mention that my gas gauge doesn't work either. When I got my Jeep it would always show that tank was full, until I smacked it on a rock. After that it's always showed the tank was empty. So I imagine I'll need to replace that float at the same time.

My poor Jeep has been out of commission for a week now, I'd really like to get the parts ordered and get him back on the road.
