Replaced the fuel pump in Feb. Broke the quick release. Hose came off a few times which caused the 43 code,as well as running out of gas. Also replaced cap, rotor, wires, plugs, checked and repaired vacuum lines. If the timing jumped it wouldn't run at all would it?

How much rubber hose did you use? If only a small amount it could be ok but check it for kinks or sharp bends. Either will cause fuel pressure issues that might only cause issues while trying to drive it but be ok while just idling. If you use a long length of rubber hose it will probably not work due to fuel pressure issues. Will work ok at idle but hose can expand causing fuel pressure to drop and as you try to drive it there will not be enough pressure to allow it to preform properly.

Also it will be to your advantage to put some sort of fuel filter in the line to keep trash out of intake/injectors.

My 94 dodge ram 1500, 5.2L, runs okay but began using lot of fuel. Had trouble codes 37, 32, and 51. Cleaned throttle body and checked for vaccum leaks or bad hoses. Code 32 gone away. Cleared code 51 which according to Haynes manual is not supposed to make the check engine light come on. Their is no code 37 in the Haynes manual for a gasoline engine on the 94 Ram. Their is for diesel engine. What is it, where is it at and how do I correct the problem. 51 I know is the O2 sensor. Truck runs great, shifts fine , but is still using more fuel than normal. Been reading about code 37 and transmissions, don't think my problem is there. Any help ? 5 Answers

Cannot get the Code 37 to clear, can disconnect the battery and the code 51 clears, The code 32 has not come back but 51 comes back. 37 does not go away. Engine light will not come on after starting...
