Trans Sport :: 1994 TP 3.8 - Overheating In 2 Minutes From Cold
I've replaced the drain plug, filled up the radiator with proper coolant/antifreeze, turned on the engine then closed the cap to see the needle going fast to near the red mark. I turned off the engine and touched the cap with my finger but it was cold so I did the same with a hose, not hot.
Well, it seems the problem was not all circuit was filled. I did add more after a while running and now it is working normally (knock wood).
Trans Sport :: Fan Motors Replaced And Radio Stopped Working
Recently I had an overheating problem with 98 Montana Transport. I had the fan motors replaced because they weren't turning. That didn't solve the problem tho, it overheated again, it had been slowly losing coolant. Mechanic had the heads repaired (were warped) and replaced head gasket, manifold gasket, valve cover gasket and drained replaced fluids and had plug wires and sparkplugs replaced also.
When he brought it back the radio wasn't working. I know that's not a mechanical problem, but why it's not working. I asked him and he said he's a mechanic and doesn't know about radios. He did say that it might have something to do with the anti theft system, but I don't have a clue how to reset. Since the van is older, where could I find out about the codes for resetting? He checked the fuses too.
Trans Sport :: 1992 Pontiac 3.1L V6 TBI Engine Refused To Start / Fuel Pump Relay Error Code
We have a '92 Pontiac Trans Sport with a 3.1L V6 TBI engine. Last Sunday evening it refused to start like someone left the transmission in Drive and the Park/Neutral switch was preventing it to start. There's the buzz sound from the fuel pump when you put the key on then nothing when you turn it to start the engine.
I checked the Park/Neutral swith by connecting an ALDL cable to the OBD port and it indicates correctly when I move the lever to Drive or Parking/Neutral. The only error code stored is "Fuel Pump Relay" but the Fuel Pump appear to be working?!
Battery is good, fuel pump fuse intact and the Park/Neutral switch appear to be working. How we can tackle this problem?
Trans Sport :: No More Front Ventilation When Engine Is Hot
These super-hot days our TS had started to develop a very strange problem:
- when you first start the engine the A/C works normally and cold air blows from the front vents on A/C or MAX as usual
- if we shut-down the engine and try to engage A/C or MAX again the cold air would only come-out through the top (windshield) and low vents - no more front ventilation
- all solenoids appear to be working (moving)
Trans Sport :: 1996 3.4L Van - No Start Intermittently / Fuel Pump Relay Chattering
I have a 1996 Pontiac Trans Sport 3.4L (without Passkey anti-theft) which on occasion won't start after being parked. The fault only happens when the vehicle has been sitting, it does not die while being driven (so far). The engine cranks normally but does not fire. The peculiar and significant thing about the fault is that the fuel pump relay (driven directly by the PCM), chatters at about a 10 Hz rate. Instead of receiving a steady 12VDC to keep it energized, it is receiving a pulse stream from the PCM.
The first few times this occurred, I heard the relay "chattering " under the hood , and was able to start the van by unplugging the relay and shorting the connector terminals for the contacts together with a wire jumper ( these terminals connect "hot at all times" 12VDC from the PCM fuse (orange wire) through the relay contacts to the fuel pump +ve). The electric pump would run and I could start the engine easily. By the time I arrived at my destination, the fuel pump relay 'drive' would be normal and I could plug the relay back in and continue normal operation.
The last few times this problem occurred, the van would not fire -- no spark as long as the relay drive was pulsing. When it would finally go back to normal operation of the relay, the engine would start OK.
Last Spring in cold weather I had the van towed 2 blocks to a Pontiac dealer with this problem. The problem resolved before they inspected it; however after the Technician's inspection the Service Advisor said there was no fuel pressure at the test port and that the pump must be deffective (shorted), overloading the relay causing it to chatter. That diagnosis made no sense to me. They wanted to replace the fuel pump as the solution ($600). I got past the Service Advisor and asked the mechanic to show me the fuel pressure -- the car started on the hoist when I tried it, and fuel pressure was normal (>30psi). I left with just the relay changed, as they thought the original would have burned -up contacts from excessive current to the pump. (I cut it open later and found its' contacts to be perfect). While at the dealership I asked the S.A. if he knew of any TSBs, or other incidences of this problem; he said he had not heard of this problem before.
I had the same problem one week later, but not again all summer until this Fall's cold and wet weather. I had to have the vehicle towed home and it still wouldn't start the next day. As soon as I accessed the PCM behind the glove box and jiggled it the relay chattering stopped and car could start. However, later the same day, still in the driveway, the fault was back and no amount of jiggling or other manipulations had any effect. Later still I went out to test for spark, and the fault was gone. (Cold, wet weather all day).
Vibration seems to have little effect. I have checked the PCM connectors' security and pulled, twisted and wiggled the wires coming from it, as mentioned above, to no effect. I suspect the fault is inside the PCM and is thermally induced by cold weather. The next time it happens I will try a warm hair dryer on the aluminum housing of the PCM. I wonder if there is a fix for this (repair a cracked solder joint, etc.) other than replacing the PCM. I work in electronics, and will open the PCM up and inspect it before forking out for a new one.
Trans Sport :: Car Won't Be Able To Maintain RPMs On Warm Start And Produce White Smoke
'92 3.8l Trans Sport owner, 165 miles on it (if I can trust the previous owner), have this vehicle for 4 years now(I owned 2.3l version before - not to recommend).
At cold start, it starts without any problem, maintains the RPMs as it should and doesn't produce any white smoke. But when I start it when it's warm(or hot, doesn't matter), the car in a lot of cases won't be able to maintain the RPMs and die. If I apply some throttle for first 2 seconds, it will be ok and it will continue to run normally without any pedal assistance. From time to time this causes a very rough start and it will miss on 1 cylinder until it warms up a bit(15 second - 3 minutes). Regardless the way of starting(assisted or normal) it will start to produce a white smoke, when I wait at stop light for 30 seconds or more and idle becomes very rough and slowly starts to miss on one cylinder.
When I continue to drive, it's ok after a few seconds, until I idle again. My mechanic told me, it's the head gasket, but as nobody in the whole world does not complain about head gasket failure on 3.8l GM engine, I'm a bit sceptical and wouldn't want to invest money on something the car does not need. People mention the intake manifold failure is common for this engine, could that be the case? Car slowly loses the coolant(1l in 2 weeks), no leaks, water pump has just been replaced, smoke was present before replacement. Ignition is OK, new spark plugs, 1 year old cables, 2 years old ICM, first coils, sparks on all cylinders.
Trans Sport :: 1992 Pontiac - Cylinder 6 Not Firing When Engine Hot
We have a 1992 Pontiac Trans Sport with the Chevy 3.1 V6 TBI engine.
Engine was running poor because of a faulty Coolant Temperature sensor (rusted-out pins). Changed the sensor and cleaned-out rust from the socket and now it runs smooth when cold with decent acceleration.
Problem is that cylinder #6 is not firing when engine is hot at operating temperature. Engine shakes lightly but performance remains good.
Distributor, rotor, spark plugs, spark plug wires and Oxygen Sensor were all changed 1 week ago with new ACDelco parts. What to check next?
Trans Sport :: 1996 Model With 3.4 Engine - Horn Fuse Keep Blowing
Looking for a wiring diagram for a 96 model with 3.4 engine? The horn fuse keeps blowing and I don't know what else is on that circuit to check. The horn works when the fuse is replaced but the fuse blows at some time afterwards.

If I press the gas a little hard in drive, my tires squeal but if I'm in reverse I can feel a slipping in the trans. If I try to back a trailer up an inclined driveway, it won't go, the trans slips. I have no crud in the pan. I've replaced the reverse boost valve. I installed a Trans-Go kit which is suppose to eliminate the reverse slip but it hasn't worked. Everything else works just fine and my fluid is red. I have engine braking in 2nd and 1st. The van backs up fine, it just does this in reverse under load.

I'm experiencing erratic shifting ending in a stall after about 10 minutes of driving. The trans seems like its searching for the right speed then the engine stalls. I've heard about air in the trans fluid, which is caused by fluid overfill and I've heard about MAF sensor which I replaced to no benefit. Right now I'm going to drain the pan, install a filter and refill accurately, especially as I have the pan off?

My Haynes manual indicates that the ELC exhausts air when the key is off. Is it intended to exhaust all air from the shocks every time I stop? It doesn't make sense to lower the vehicle every time I stop for fuel etc. With over 200k miles on this can it's amazing that the compressor still works.

I am working on my daughter's TS, it has been overheating. Water pump is fine and the thermostat is working fine also. I did notice that the temp gauge on the dash isn't. I have noticed that the fan isn't coming on either. I don't have a book on this car or a owners manual. So I am unsure of which fuses to check. I did try turning on the AC to MAX to see if that would start a fan, and that didn't work either.
View 13 RepliesTrans Sport :: 1994 - Oil Puddle Underneath The Car
I replaced my '94 TS intake plenum and upper and lower intake gaskets last year, and as part of the procedure I replaced the badly-degraded rubber gaskets that go at both ends of the manifold (at both ends of the "V", one under the throttle body, one under the PCV valve or so).
A little more than one month ago I realized the oil puddle underneath the car contained -besides power steering fluid from a known leak- motor oil. When I investigated the origin of the leak, I discovered the <> rubber gaskets have disintegrated AGAIN.
I don't see how this gaskets could be installed incorrectly, so I have to conclude the gaskets that came with the kit I used (Felpro?) did not withstand the oil as they should. Either way, I need to replace those <> pieces of rubber again
Now: since I don't want to be doing the same thing every 5 k miles, any good brand for these gaskets? Is there a material (neoprene?) that would last longer in contact with the oil?
Trans Sport :: 95 TS 3.8L Misfire When Reverse Is Applied
My 95 TS 3.8L is misfiring on #4cyl ONLY when reverse is applied. When car is in reverse with parking brake applied, consistently misfires on #4. In drive with brake applied and engine load no miss. Neutral no miss.
Car drive ability is great in drive no misfires. 100% misfires on #4 only when in reverse. Is there any vacuum change or assist utilized with this trans? Possibly vacuum leak? I do not have a vacuum gauge. I changed to a different plug wire and same problem. New plugs installed. Have not swapped coils yet.
I am not familiar with this trans, other than the vacuum servo for upshifting I replaced when it was sucking up trans fluid like my old Powerglide in the OLD days.
Trans Sport :: CEL Started Come On Then Shut Off - EGR Fault
Just recently the CEL started acting...first, would come ON then after some time would shut off....but now it is ON and stable. I was almost sure it had to do with EGR....checked codes and indeed, 55 , large EGR port failure and, accordingly, 56, QUAD driver faulty voltage...obviously because of large EGR port solenoid control. I have not verified the EGR coils yet....will come back later as I'm going out for 2 days.... This is a rather new EGR valve...6 or 7 year old.....and in fact, no more than 25000 miles...probably less...
View 8 RepliesTrans Sport :: 1995 TS 3.8 - Slow Cranking When Hot
Our 95 TS 3.8 runs hot. I dislike the 195 Thermostat, but winter is coming. Temps can soar to 230 on gauge, with no air.(Now I remember why I had a 180degree thermostat).
I recently replaced a rebuilt delco starter that was about a year old.(faulty solenoid). I cannot recall if the Slow crank problem was there prior. When 230 degrees, intermittently I get a slow crank with dimming of dashboard lights, but bright headlights.
1. I know that the temps are supposed to swing a lot with this vehicle, but 75 degree days, 230 degrees when in heavy traffic is pushing it.(gauge). Is this normal for 195 thermostat?
2. Possible bad windings on new rebuilt starter? Armature drawing excessive amps when hot? Battery cables look okay, but original.
3. Considering a NEW starter and a heat reflector wrap for starter. New battery cables-thicker cable if possible(used welding cable for my old 421S.D.
