Question about 1994 Chevrolet Suburban

1 Answer

Engine quits/difficulty starting 94 diesel suburban

4 or 5 times while driving at varying speeds with a warm or cold engine the engine just quits. After pulling to the side of the road it has, so far, always restarted. Systems that rely on the engine like power steering also quite but the radio and other electrical systems that only need the battery were fine.

Once when cold it would not start. The battery is new and I had plenty of battery and cranking speed. I did not smell exhaust or fuel while I was trying to start the engine which leads me to think the problem is in the fuel supply system but I don't want to put extra thoughts in your mind because I really don't know anything about diesel engines. After 15 minutes I tried it again and it started as if there had never been a problem.

I cannot tell if it is electrical or fuel or? But it is sudden. There has been no engine missing or hesitation it is running perfectly and then dead.

I have taken it to Carr Chevrolet in Beaverton, Oregon. They have started it several times and take short drives over the past two weeks and of course it has worked perfectly. They tell me there is nothing they can do until it stops again and won't start.

Is this a common problem with the 94 diesel suburban? Do you have any suggestions? I suspect that Carr does not work on a lot of diesels should I try someone else.

Thanks in advance for your help.

I want to say that it sounds like the fuel solenoid closing . if the solenoid is going bad it will happen more frequently , if you have a cam sensor on that engine that would be the other possibilty .

High rev at cold (winter cold!) idle


Your toyota technician should know what a "cold starting solenoid" is. It is the little thing that works your throttle until the motor warms up and something else takes over. I'd suggest going to another technician.

Error code po0117. Vw beetle


16501/P0117 - Engine Coolant Temperature Sensor (G62): Signal too Low Possible Symptoms
  • Difficulties with starting a cold engine.
  • Starting the engine when engine is warmish or warm, idle rpm immediately is 1200 - 3000 rpm.
  • RPM at idle is irregular.
  • With all engine temperatures seldom idle rpm will vary between 900 - 1000 rpm.
  • With engine warm (90 °C) the engine temperature suddenly drops (70 °C) and slowly comes back to 90 °C.
  • Bad acceleration during warming up.
    • Diesel: an indication is extreme long time burning time of the glow indication light.
Possible Causes
  • The electrical signal coming from G62 is too low
  • Wiring and/or connections faulty (short circuit?)
  • Engine Coolant Temperature Sensor (G62) faulty
Possible Solutions
  • Check wiring and connections
  • Check / Replace Engine Coolant Temperature Sensor (G62)
Special Notes
  • In MY 1995-2002 (?) in Europe at VW-cars the G2/G62 had the bad reputation of breaking down often. The default G2/G62 is black and all replacements are green.

Where is the thermostat on an Audi A4 diesel, 1998


Heed of antifreeze solution temperature!!!
You must check the thermostat operating. The thermostat location is on back of alternator at the bottom side of the bracket. IMPORTANT: It is NOT necessary to replace the alternator if you want to change the thermostat !!!
Thermostat checking:
1. Cold engine. Start up the engine and watch of the water temp indicator. After first value 60 Celsius Degree you still warm up the engine until the lifter (pointer) reach 80 C deg. (second mark after 60 C deg.). At this time you let engine running at idle speed and check with your hand the thermostat plastic housing and hose temperature in bottom left side of the engine. Heed of alternator driving belt and ventilator fan !!!
2. If the thermostat is good the hose must be cold until the water temp indicator reach almost 90 C deg.
3. The thermostat opening temperature is 87 C deg.
4. If the hose is already warm the thermostat is out of order.

Help...94 Suburban 1500 auto 4x4, I am changing


I'm pretty sure GM built your truck with the diesel engine as an option so there is a way to make this work. The trans shifts are based on a combination of ground speed and engine RPM so as long as the computer is able to get these signals your trans should work. I put an early 90's overdrive in a mid 80's truck and didn't plug the wiring in because the trans used a 4 wire plugin and my truck only had a 3 wire. It worked fine, even overdrive.
A little jury rigging and ingenuity should find a way to attach your current kickdown cable to the accellerator on the diesel pump. GM probably has a bracket to make it fit. Check with the parts guys at the counter. Hope this helps.

Voltage intermittent, engine missing at all speeds, affect auto trans. shifting, kills hot or cold


The charging system, pedal, and sensors have been checked. The trans. problem and missing problems were the original problems and when my mechanic finally sent me to Chev. none of the problems " choose to show themselves." I should know on Mon. if my mechanic has solved the problems with the greater number of symptoms. Keep me in your files. More later-  Bill
