Hello. We just replaced the fuel pump in out 1997 Chevy S-10. It still is stalling once you start driving it. It also was put on the computer and they said there was nothing wrong with the electrical side it was the fuel pump so we paid like 600.00 to replace the fuel pump and we are still in the same situation. Anyone know whats going on. What should we do next?

Know you've had the cooler lines and the intake gasket problem. Just recently had the intake gasket replaced, along with valve cover gaskets. Problem is I'm hearing a sloshing sound from the cooling system from inside the vehicle. Basically first start up my rig, can hear what I believe is coolant flowing through the heater core and through the system. It's almost as if it's filling up the heater-core. Also, when I come to a stop (like a light or stop sign) can hear the coolant sloshing; then starting from the stop, can hear it slosh again. Once the temp hits normal, may only hear it once like when doing a sharp turn.
I'm thinking there's air trapped in the system. My rig's not overheating, the coolant is new; replaced the hoses and thermostat less than 6 months ago; no leakage since gaskets replaced.
Was wondering if you had this problem and if so how did you solve it. Right now I'm dazed and confused

I believe you are correct in your assessment of air being trapped in the system. You need to purge the system of air. I haven't had this problem with my truck. Consider pressure testing the system and also replace the radiator cap. See attached link it may be helpful.

Will be doing this myself. Had the vehicle in twice (once for the initial repair & back to have the air removed) and still have a slight sloshing / bubbling effect. Plus can put a decent squeeze the upper hose and somewhat on the lower and hear coolant gurgle a little.
Am going to pick up a pressure tester.
Thanks for the link

Two other wild suggestions ;
Is there any chance that there is a blockage in the heater core ?? A Restriction may cause it to require excessive time to fill/ "squirt through" and fill the core causing the sounds you are hearing ??
I'm not sure where you are Geographically - but (again a long shot) - Could trapped water in the air conditioner drain pan (from outside water - or air conditioner condensate usage) be part of the noise you are hearing ???
Good Luck - and let us know what you find !!!

So - per you last response - it sounds like it's at "Highest torque" (Low speed - highest gear) - So I would have said the motor mounts etc ... but you did this ... So I have two thoughts ;
Torque Converter problems ?? - was this Tranny/converter EVER taken out before ?? (http://www.txchange.com/tcinstal.htm)
Or #2 - Cracked Flywheel ...
Both, I'm sure, you do not want to hear - but Try Surfing the net for vibration problems (ie, Torque coverter vibs, Flywheel vibrations, etc ...)
I hate to pay a dealer for anything - but sometimes you drive in - the tech take a look / ride and immediately says - oh sure, I get a lot of these and it's always XXYYYZZ. If he's right - it's worth the diag fee and beats replacing - or just pulling - parts/trannys -"just in case" ..
Let us know how you make out !!!
#1597 of 2018 GMC Sonoma ZR2 Rattle
Mar 16, 2006 (8:31 am)
I have a 2003 ZR2. I have had a large number of problems that are all fixed at the moment. From day one, I have had a rattle coming from the driver side front. Dealer thought it was ball joints and found the two lower to be loose. Replaced them. Rattle still there. I found info about hood rattles and installed the fix. Rattle still there. It sounds like a loose shock or brake caliper, but they are tight. I am starting to think it is a motor mount, although the dealer said they were good, or something loose in the steering. No noticeable loose items in the suspension or steering. A friend said to tighten my front swap bar. I did but the rattle is still there. Is more noticeable during cold weather. I may tighten all rubber mount suspension components and see if it persists. It is random and more noticeable on pavement that is rough or rough hard terrain. Any ideas? At 93k miles, I'm very tired of hearing this random rattle.
Please help! I love the truck, even with all of the issues I have had that are all well known.

I noticed tonight on the interstate running around 75 it's not as noticeable as lower speeds on slower streets. But the vibration is still there just the same.
Thanx for the reply.

Hey Kris, I've got a 94' sonoma with a similar problem. All lights are off but something is draining the battery. I've had to disconnect the positive cable on the battery if I ever leave the car without starting it for more than a day. There is a drain somewhere but I haven't found it. Next time you jump your truck, tap the negative cable with the negative battery bolt before you start the truck. If it sparks then something is "on" and draining the battery. If you figure it out give me a shout. I'll let you know if I find anything.

Try this - if you have notalready .... When driving on a deserted road - say at 35 MPH and you feel the vibration (and do this carefully - as if you screw up you can lock the steering wheel ) - Shut off the engine with key and coast. If the vib is still there - it's not from "Torque" of the engine and it's not from the Engine mounts, etc ... So If It's still there I'd say it has to be from the Drive shaft to the rear ... - or - not even in the drive train but in the Suspension wheels, etc ....
Also - Did you check for a "Bent" or Warped rim ???
