  1. Heater fan will always run, tried that, so now I'm leaning more to that we could be losing prime. Will try and find the stuff to try the pressure and sight glass idea.
  2. My first thought was we were losing prime but have come to realize that we aren't. As soon as you turn that key off and try again it'll fire right up or try one more time guaranteed. You could crank it for 30 seconds and it'll never fire, you could do this 4 times and it'll never fire. Turn key off and back on and crank a second and poof its running.
  3. Have owned this truck for over 20 years so know it inside out. Have had trouble starting it lately, crank it for 30 seconds and it won't go, crank again and it won't go. Turn key off and pump up injector pump and it'll fire up instantly. Just seemed strange. Have now figured it out that if it doesn't start within the first 5 seconds of cranking, turn key right to off, try again and it'll fire right up. Next time it might fire right up too. So its almost like the fuel isn't getting turned on. Its a 95 Mack with the E7 350. Only thing I'm thinking is that its the computer or may be the voltage isn't right somewhere. So it never leaves us stranded but the first time in the morning it may not start right away until you try a couple times and turn off the key all the way each time. Any ideas??? TIA
  4. 95 e7-350, also only 26 lbs of boost. Pulls good tho. Our 427's get over 30lbs. 23000hrs on the 350. Only time I've ever remember a flutter issue the the throttle threw a code and had to replace the foot pedal
  5. If you tap the dash to the right and below the speedometer, thats where the buzzer is. Quite often ours quit but start once you tap where the buzzer is situated
  6. On truck 2 we had the issue and it was cracked head port which would allow intake air from turbo to pressurize coolant system. coolant never leaked back tho when it was stopped. Heads got checked for cracks was how they found it after we did so much other stuff
  7. Had the peanuts in the power divider giving us grief and clunking. If we engaged the power divider it wouldn't do it anymore. 46000 mack rears airride
  8. I think my 95 and 97s are terrible. Have the butterfly in the exhaust too which helps as the Jake isn't much help
  9. I did my 95 Mack, it had eaton rears and Mack front axle. I was able to get the rears from a truck parts shop but the Mack front I had to get from Mack. I couldn't find any at a wrecker. Prices weren't that bad but I'm not sure what the rear mack ones will cost. In fact I can't remember what I paid for any of them now. The bearings took some figuring out and a good old parts man came too my rescue as numbers changed a bit. I jumped to 24.5 from 22.5 as well and now all my trucks and trailers have the same tire size which is what I wanted.
  10. We've had issues with vibration at 55 mph and king pins and bushings are wore. Sometimes we can change front tires side to side and it goes away.
  11. A drop in 427 from Mack cost me $12000 canadian. This was quite a few years ago. With labor and extras it was pushing $18000. Maybe cheaper in the States but it'll be up there.
  12. on the 97's the relay and fuse panel is under the dash in front of the passenger seat. Not sure if the 2003's are still there or not
  13. The clicking is probably the relay, I have had to replace the motor pump assemblies before. Easy job on my 1997 Ch's so should be the same as yours. You could always put a test light on the wiring when you unhook from the motor and get someone to push the button. The pump is attached to the washer fluid reservoir.
  14. I have a 1995 ch with the electronic 350 and a 9 speed and I think it is great. Purchased it when it was about 5 years old. First thing we did was pull the injectors and pump. The injectors were wore and this really spruced it up. The engine now has 22000 hours and 1,400,000 km. I added a turbo boost gauge as well and maximum pressure for it is about 26 lbs in the cold weather. I have 2 other ch's with 427's and one with a 454. We drag raced the 350 and the 427 each hauling tandem loads of grain in the field and they stay side by side until you get to the last couple gears so I see no reason why it should feel doggy. Also I've never seen my pyro over 900 degrees ever on the 350 Hoping this helps you a bit Glen
