We'll know soon enough!

 

Well the fuel gauge bobs up and down now like a faulty sending unit not like before it would only read till 3/4 tank then drop like it wasn't reading at all, only works solid when parked. I see myself dropping the tank in the near future and trying to fix it like the post here says http://dodgeram.org/tech/repair/fuel...sender-diy.htm its a shame you can't just buy the unit when it just screws right on to the Module.
Thanks for the help, I will try to help here too as i can, but I only am a back yard mech that worked for Chevy for 4 years. But i do love to try to solve problems on cars.

 

Hmm, I wonder if your engine to body grounds are corroded or loose! If so it would definitely cause a wandering fuel gauge and it can also cause stalling.

 

I will have to get back to it on Monday, The wife says i can work on my cars all week long BUT she gets me on the weekends starting at 3:00 on Friday.. funny though if Her cars are broke I get to work on cars 24/7. But then again she only has a 79' Z28 and a 93 escort, I have 75' Rabbit, 75' Chevy Monza (yes the 350) , 66 Ford F100, 74' Sportster, 75' F150 and the 93 B350 being a lover of older cars ya need to work on em most of the time or doing body work.

 

BTW do you know off hand where the engine to body grounds are, its tight in there and hard to see things at times..

Thanks

 

I have some of your same problems. Fuel gage just sits at the empty and bounces around...i am told the sending unit is probable bad. The 360 engine started to run weird in the morning when it is cold. Will almost stall and then speed up to above idle speed and then sputter and do it all over again...just like a crazy car. Once it gets warm it all stops and works like normal. Have been told there is an air temp sensor that is located in the intake manifold that controls this but am not sure. Anyone have any ideas? Could the Oxygen sensor do this too? Today I unplugged the air temp sensor and will see what that does in the morning. Now that the engine is warm unplugging this sensor does not do anything except turn on the engine light.

Thanks for any advice

 

I would start by cleaning the throttle body and the IAC I saw a recent thread here on cleaning the IAC. if its not the problem it wouldn't hurt to clean them anyway. the O2 sensor to my knowledge would make a problem happen all the time and not just cold.

 

I saw that tip also on the IAC wish people would id these acronyms so they make sense...but anyhow I understand that my engine probable does not have one. This is a 1993 B350 van with a 360 engine that has one of those carburetor that is actually fuel injection. Is this IAC on the side of the carburetor that is facing the front of the engine or the rear?

Thanks

I am also going to try replacing the air temp sensor since this happens only when it is cold. I have disconnected the connector to that sensor and am testing tomorrow morning to see if all this crazy surging and sputtering will occur with that sensor disconnected. If so then I will replace that....naturally it is a B to get to as it is right where the engine goes through the firewall.

 

I have a 1993 b350 dodge van with the 360 engine and am trying to find the air temp sensor. Does it even have one? The auto parts store showed me one but I can not find anything that looks like in on this engine. Maybe there is one for another year ? This is a 93 5.9 L or better know as a 360 cu in. with fuel injection and california emissions. Would love to know if it really has one and if so WHERE!!!!

I thought what I was disconnecting was the ATP but it was the water temp sensor. Maybe this years 5.9L does not have a sensor. I just do not have a shop manual...wish I did.

 

This engine does not have a sensor....replacing all the plugs, cap amd rotor along with a new set of wires fixed the problem....or seems to...will find out in the morning when it is cold.
