2800rot./min when driving. engine showed signs that he drowns, I joined, he went shortly after that began to fall speed and the engine stopped. Then I could not start. Come to be fuel, received a little dirt somewhere and no longer feeds? What can I do?
View 3 RepliesLast week, the engine stopped twice in the 2 minutes after initial start....but then managed to take me back home. Was away for 1 week (not with TS) then when back , tried to start ...no joy.
This duplicates a similar event 8 years ago...solved with the ignition module being replaced.

NO codes.
There are 2 options: crank sensor or ignition module. Will go for some tests and will report.
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?
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?
When is cold, the engine starts but stops after 2-3 minutes. I can not start until after standing for 2-3 hours, and again stops.When I try to start, signs that would not fill with gasoline.What should I check first, what should be changed?
It was....now engine don't start!

I have a 97 Pontiac Transport and I was traveling down the road and suddenly i lost oil pressure the light came on and it started clattering so I checked the oil level and it was fine so i had it towed home. I changed the oil using a higher grade oil and lucas oil treatment and started it ...I still have the problem what do i do...
View 7 RepliesOne of the '92 Pontiac Trans Sports (3.1L V6 engine) had developed a huge thirst - the fuel consumption had doubled along with a serious loss of power. All ignition components - distributor cap, rotor, spark plug wires and oxygen sensor are new ACDelco's.
ECM is not throwing-up any fault codes but we suspect a vacuum leak since this engine runs better with the air intake covered-up almost completely.
Is there any way to trace and fix this kind of issue? Any vacuum diagram for this car - I couldn't seem to find it in the GM Service Manual... How would you suggest we proceed?
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.
I have a 1997 Pontiac sunfire the other week I was driving and it stopped on me the engine would crank but quickly turn off but everything inside the car would still be on k was told I needed a new cat and got that and a new muffler put on. This morning I went to leave for work and the same thing happened again! I was told it could be the fuel pump or fuel filter but it doesn't act weird while driving it. What could this be?
View 7 RepliesMy 92 transport 3.1L had started quitting on me while driving. After sitting for about 15mins I could get it started and then continue on driving. Now its doing it more and I can't take the chance of going anywhere in it.
Got a CEL so I flashed codes 34, and 45. Where to start troubleshooting with what these codes are saying that I should do?
My 1995 TS with 3.8 just quit driving down the road, would not restart. had to be towed home.
Fuel pressure just meets specs at 41 PSI engine off ( Gm says 41 to 47), but has been that way for some time. Put Actron scan tool on, got a code 361, EST not toggling. GM has no code 361, but based on past experience, this has usually pointed to a defective ignition module, and I thought that was that. While testing, scan tool kept losing communications and having to be reset.
Finally I unplugged power source of tool, and engine immediately quit and would not restart. Resetting scan tool would allow engine to restart, albeit very rough. Doing a wiggle test of engine wiring harness makes no change.
Crank sensor was replaced, about 12 years ago, so it not the trouble prone OEM; cam sensor about 10 years ago by a garage who was unsuccessful in solving a driveability issue.
Issue here is why would scan tool affect engine operation?
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)
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.
'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.
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.
View 5 RepliesIf 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.
View 2 RepliesMy 2000 ranger, 5 speed, won't start. I was driving, and all of a sudden, the engine just stopped.
Electrical works, engine turns over once or thrice, but it never actually turns on. Wires and belts all appear fine.
for the last 5 months, i have not been able to use my 2012 sonata which broke down in October last year and has since been in the dealership in Dubai and they have never taken any action. what happened is that the car just stopped when I was driving at normal highway speed. no indication, warning or anything came up. the car just stopped and did not start any more.
when the car got back to the dealership they called me after a few days and told me that my engine block is completely cracked and the whole engine has to be replaced. I don't understand this, the car was only about 16 moths old and has 23,000km on the odometer. the car was always serviced and never driven erratically. until today no one from Hyundai took any stance to the problem
I have a 99 pontiac grand am that sometimes won't start and lately it is cutting out when I am stopped and idling at stop lights/signs. And today it just died when I was driving, it started right back up, then died again about three times, then it seemed to be fine, I drove it for about 2 miles and it just died and won't restart. We have replaced the fuel pump, fuel filter, ignition switch, fuel relay fuse twice, air filter, and some sort of module.
View 5 RepliesI was driving my sport trac when it suddenly died on me. We are leaning toward the fuel pump. But is there any other causes for fuel to not get to the engine? We changed the fuel filter out already...
View 4 RepliesI have a 2003 Sport Trac that basically died last night on me. I drove it 30 miles Shut it off for about 10 minutes came back out and it cranks but it will not start. I sprayed some starting fluid into the throttle body and it ran for a second, so it's definitely a fuel issue. I am just not sure if it could be a fuel pump, Relay, or a dirty Fuel filter (I have not changed in the 87K I had the truck). Because it ran fine before it died..
