Tahoe 97 Fuel problems

If you have a smart phone download an app called ' torque '. I got mine for $4.99. Then buy a bluetooth OBD2 scan tool to plug into your computor.. Elm makes these. Usually around 12 to 15 bucks. Your phone will give you the error codes and take you to a website that will explain them. Fix it with the right parts yourself and save money.

scroll down to your code and open code. gives symptoms and possible fixes

I had same problem on my 97 tahoe shut off while driving and wouldnt start only turned over. checked everything and when i replaced ignition module started right up no problem. Hope this helped and saved ya money

I'm assuming you replaced the fuel filter when you did the pump.
You'll have to try to figure out if you are loosing fuel to the injectors or spark to the plugs to proceed.
Its possible something is failing inside the distributor among other things.
I'm also assuming you have checked the computer for trouble codes.

Not the alternator, but a fuel pump or fuel filter could be the problem. BUT it depends on the indications. A fuel starvation problem would act like it was lunging and then dieing out before it died. If it just dies out suddenly, then I would suspect an electrical problem like a coil pack or cap.

check the flexible pipe or just change the pipes as they collapse inside ,

A code P0171 may mean that one or more of the following has happened:

• The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filter may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
• There could be a vacuum leak downstream of the MAF sensor.

  Possible solutions include:
  

• In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
• Inspect all vacuum and PCV hoses, replace if necessary
• Check for a dirty fuel filter and proper fuel pressure.

alternator is going be the problem, when that stoped working the car was running off the battery when that died your car cut off.

P01345 IS related to curicut falure on CMP/CKP sersors respectively.This is not a good code to get.And hard do diagnose . If you have replaced the crank and cam p sensors and the distributor shaft and have a good spark and can dump fuel into throttle body and it will run. All that leaves is the fuel injection system not supplying enough fuel or the exhaust system Cat not letting the burned gase's out to much back pressure or your valves are really shoot. What do your spark plugs look like this is the best way of knowing the engine health. Get back to me

This starting issue sounds like either the ignition timing is way off, or the cam timing is, the whinning sounds like the timing chain may have been replaced with a non silent type chain (plastic cam gear teeth), maybe the onwer got this wrong when he installed it and the cam timing is off.
