Broken down. Fuel pump issue?

We have a 96 fleetwood southwind with a big block fuel injected Chevy engine. We are stuck in a Walmart parking lot. The engine started sputtering and stalled out. I was able to get it restarted and get to an auto parts store and put a new fuel filter on. It started right back up, went another ten miles and it died again. The pump in the tank is coming on when the key is turned to acc. I'm getting fuel up to the top of the engine before the injection system. I'm getting spark from the coil, but it still won't start. I was just able to get a fuel pressure gauge and will check it in the morning, but I'm looking to find out what the spec is for fuel pressure on these injected models is. I figure the pump must be wearing out and when it gets hot it quits, but I would like to know what pressure it should have before I go through the trouble of dropping the tank. Any help would be appreciated. It's not going to be a fun trying to get it done in a parking lot.

surfside, you're my kind of guy. i have to give you a pat on the back for a job well done, persistence is the key.
i had a water pump lock up on me in las vegas, and it was also at a walmart.
the manager let me pull around back so i would be out of the way. i was able to replace the pump at night because the outside temp was 110 degrees during the day.
thanks to that manager i was able to solve a problem that the local dealer said would take 6 days.
i have done many repairs at a walmart parking lot as i travel between jobs.
lots of folks talk down about walmart, but i think walmart is great. all you have to do is ask.

I now have a 2800 page chassis manual for a 96 P30 including motorhomes. I would be happy to share whatever information needed.

Thanks for everyone's help.

1996 was the year Vortec came out but there were also many built with the TBI in the same year. They could have been leftover chassis.

I only bought the pump and the pickup screen that goes on the bottom of it which is sold separately.

Also I wanted to post this link since this is a really good troubleshooting guide that I found. I'm sure it will be helpful for someone:

Surfsidewood,

I am going to trouble you with another question. Did you buy the entire sending unit with a pump, float, & lines, or just the pump module??

Thanks,

This man is my hero! That is enough stuff going wrong, all at the same time, to make a person want to push it off a cliff! You methodically fixed things one at a time. Perfect!

Newbies need to read this. You need to be handy with a wrench. Or, you better be ready to pay someone dearly and wait. Wait until they have time to deal with you.

Awesome!

Thanks for the info, it has really helped. Luckily for me mine stopped under a gas canopy, with a towing service behind the station, and a brand new motel just around the corner. Everyone involved around Pioneer, TN was very helpful, It could have been a much worse situation if not for the locals kindness.

I ended up getting the fuel pump from advance auto parts. I don't have the part number, but I told them it was for a 1996 P30 with the J vin code.

I also found this to figure out what the fuel pressure needed to be while I was troubleshooting: http://www.askatech.com/AskATechLive/AatFileShare/References/FastTrack/G083.pdfhttp://www.askatech.com/AskATechLive/AatFileShare/References/FastTrack/G083.pdf

Definitely will never forget that trip! The first day we we broke down, we ran out of propane and had no heat. The gauge must have been stuck on a 1/4 tank, so I thought we were fine, but it was completely empty. Me, my wife, and 2 teenage daughters all had to sleep in the same bed to keep each other warm that first night.
When I got up the next morning it was 34 degrees inside the RV. So I had to make getting propane my first priority so I could get the heater cranked up. It was new years day, so nothing was open. I even tried to call amerigas' emergency line to see if they would come fill me up, but they wouldn't do it. Luckily I had a small gauge for a gas grill propane tank in one of the storage compartments, and realized that one of the brass fitting were the same size as one of the fittings on the regulator of the on board propane tank of the RV. So I took the fitting apart, screwed in the fitting from the gauge in line with the regulator that is plumbed in the RV and now was able to screw on a gas grill propane tank which I bought from 7-11. That stopped most of the whining that was coming from the three girls which was a major plus. At least now they weren't freezing.

All this time the generator wouldn't start either (It worked perfectly fine the whole trip and the morning we left), so I was trying to troubleshoot that at the same time. I ended up switching one of the house batteries around with the starting battery, and got the generator running. That was a huge step because now, at least there was heat and the girls could sit inside and watch movies in comfort while I tried to figure out what the hell I was going to do. Then I switched the other house battery around with the now bad battery that was in the starting battery position. I tried to start the engine one more time and waaalllaaaa, it started right up. I quickly gathered my stuff together and hauled booty up two exits to where there was a WalMart and it died in the walmart parking lot. First thing I did was went and got a new battery from Walmart and replace the bad one.

Now I had heat, the generator was running, I had a full tank of fuel, but running low on fresh water, and my gray and black water tanks were almost full. At least now I was in the middle of a decent city with options for food, parts, etc. I would have had to wait until Monday to get towed to a repair shop, so I decided to drop the fuel tank in the parking lot myself.(This was on Saturday).
I bought a cheap skateboard from walmart, and rode it to the auto parts store a couple miles away to get the fuel pump. (I've been surfing since I was 17 years old, so it seemed like a faster option than walking)


I ended up talking the manager at Walmart into letting me borrow a pallet jack and 2 pallets that I used to hold the weight of the fuel tank while I unbolted everything, then when I had it all unbolted, I used the leveling jacks on the rig to lift the back end up away from the tank. It worked out great. Getting everything situated to go back together was a little more trouble, and took me a while. I had to have the tank hanging off the front of the pallets half way to get into place, and at one point the front end of the tank was on the ground and the back end was up against the frame. I had to use a pump jack under the front of the tank to get it back up on the pallet. Once I got the tank back in place and bolted I realized that I forgot to guide the fill tube onto the filler neck as I was putting it in place so it was smashed between the filler neck and the frame. That took me about an hour to straighten out and get put on right.

Once everything was back together, thats when it started right up, and stalled a couple times as I said above. Got back on the road, drove for four hours, stayed overnight, got up the next morning and drove some more, then thats when the crank sensor went out.

Definitely not something I want to do again, but I know we will be able to look back and laugh a few years from now. I think it will be a good lesson for my kids to see all the trouble we had, and that I was able to keep a cool head and work through it. At least I like to think so! It's like my brother says, the best stories never come from when things go right.

Where did you find your fuel pump? Do you have a part #? It is likely the same one I need.

Sorry for the late reply, but I wasn't getting emails saying the thread had new posts.

So I ended dropping the tank in the parking lot (tons of fun by the way since I just filled it up before we broke down), and replaced the fuel pump. After I got the fuel pressure gauge, I checked it and it was showing a little low. The spec shows it should have 55-62 psi when the key is on but not running. It was showing 48 psi. After I put the new pump in and got everything together, it started right up, then as I let it run it would stall. That happened about three times, and I figured it was just bleeding air out of the fuel lines. I started it up one more time and let it sit there running for 2 hours while I cleaned everything up and got something to eat to make sure it wasn't going to die again.

We got on our way back to FL and after about 8 hours of travel, with multiple stops and restarts, with everything working perfect, it decided to quit again in GA. So then I was stranded on a country road with nothing around at all. This time I checked if it was getting spark and it was not. I figured it would either have to be the crank sensor or ignition module, so I took a 40 mile round trip cab ride to the auto parts store and picked up both of those parts. I put the crank sensor in first, and it started right up like it was brand new, and ran perfect the rest of the way home.

I guess it's possible that both parts could have went out at almost the same time, but I'm kinda thinking that the crank sensor might have been the culprit the whole time. The only thing that doesn't make sense is that the first time it died, I checked for spark and I did have spark, which made me think fuel pump. After the second time it died and I didn't have spark it made me think of the crank sensor.


Hey Surfsidewood,

If you get some time, want to tell us your adventure of changing/dropping the tank in the parking lot, like did you drain the tank, how did you drop it, floor jack, etc. Would love to hear about it.

Glad your up and running!!!
