Question: I have a 2001 Pontiac K Prix that stopped running, I have put a new fuel pump, and new computer box on it, but information technology withal wont first. Can you help me,, please, it is driving crazy
Answer: There are mode besides many things that can cause the car to stall and not start. Do you lot accept spark, fuel force per unit area, injector pulse, theft or security light on dash, etc. You demand to start by diagnosing the basics.
1994 Grand prix 6 cylinder engine. Car stared missing, was told it was EVAP purge solenoid. Replaced it and drove fine for short time and problem started once again and once again was told it was EVAP purge solenoid. Why is this happening over and over again. What can I do?
The purge solenoid would not be causing an engine misfire. It would cause a check engine lite aye, but not touch on the fashion the engine runs.
I have a 1994 Buick Century and in the last month or so the engine started making a noise that sounds as if information technology were literally was a diesel fuel engine. When opening the hood one might there was very picayune or no oil coming upwardly to top end. Cheers
It is possible you lot accept low oil force per unit area, a bad lifter, or more probable one of the rocker arm studs has pulled out of the cylinder caput. This would as well cause a misfire on that cylinder. Removing valve covers for inspection seems the next step after checking oil pressure.
How practise I remove the TPS shaft from the throttle body? It appears stuck from the right side (every bit viewed from the drivers side). The trivial slice volition not come apart on that side to release the shaft.
If you are trying to remove the throttle plate shaft from the body, information technology cannot be done. If you have a trouble, the throttle trunk needs to be replaced every bit an assembly.
i accept a Chevy Impala that keeps proverb low coolant level merely theres no leak that i can come across and we changed the thermostat and reset the computer in the automobile and it notwithstanding says that, what could information technology be? The temperature sensor?
Cannot exist the temperature sensor or thermostat. The light say "Low COOLANT". If the coolant is low, you have a leak and need to get it inspected closely. If it is not low, so you lot may have a level sensor trouble.
1999 Pontiac Grand Prix demand to know where the low coolant sensor is. The light flashed depression coolant all the time and information technology has enough of coolant and its not running hot at all.
The low coolant level sensor is in the passenger side of the radiator. Below the radiator cap. Information technology is a square black sensor that snaps into the radiator and held with a clip.
I have a 2000 chevy impala and temp gauge rises to the red but I don't heard any over heating or humid noises simply I do hear a kind of hissing noise. What could information technology be? The temp sensor I'one thousand guessing.
If the temp judge is going into the ruby-red, it is overheating whether you hear information technology or non. You'd have to try and find the exact cause. Information technology could be annihilation from a water pump, intake gasket, head gaskets or even radiator. I highly doubt you lot but have a bad temp sensor. Go it checked out soon, or y'all'll terminate up losing the engine.
2004 Grand Am gt 3400 v6 and it wont start. The security light isn't on only its non getting whatsoever spark and i cant hear the fuel pump. Fuses and the ignition module isn't getting juice forth with others. Replaced fuse same issue.
You should re-check all your connections, and make sure all vacuum lines are connected and routed properly. If it idled fine before yous did the heads, it has to be something you did in the reassembly procedure. If it seems like information technology running crude, you may have switched button rod positions past accident, that will cause the car to dice out or run rough. If the cheque engine light is on, get the code scanned to come across what might exist causing the trouble.
I have a 2001 Olds Alero, 3.4L. I take been having problems with the Temperature gauge working when it wants to. At time it will work fine, other times it will completely drop out and the electric fans will kicking on. It will eventually come dorsum on, on it's ain. I've checked the fuses, they where adept.. I've replaced the Temp sensor and it's had the same event. I've ohmmed out the harness and it is practiced. The wires are non frayed or broken. I have no inkling at what else to look at.. Whatever suggestions??? You call up it could be the estimate it's cocky?
Probably not a problem in the dash gauges, since the fans come on. The dash does non command the fans, the gauge shows what the computer thinks the temperature is. Either a wiring trouble or bad estimator.
My 2004 three.4L has a starting upshot when the engine is warm. It starts fine when the engine is cold. I tin can barely step on the gas pedal when it is warm and it will start correct upwardly. I have cleaned around the throttle body butterfly and this did no help. Any ideas what may be causing this? I did also see when cleaning the butterfly that there is a opening merely past the butterfly about the size of a dime that goes downwardly had some carbon build upwardly coming out of it. I cleaned it out what I could only did not help.
That opening is the idle air passage for the control valve (IAC). Sounds like you take an idle valve that is not working. Yous could try to remove it and clean it real proficient.
2000 Chevy Impala 3.8 and my heat get hot when riding in my neighbor but only blow out warm air when riding on the highway. What tin I do to make my heater blow hot air at all time.
First bank check the coolant level. If it is OK, you could have ane of several problems- A sticking thermostat, plugged heater core, temperature door actuator motor in the dash, etc. Whatsoever one could be faulty.
1994 Buick century with a 3.1 recently replaced fuel pump. Won't start yet accept 40 psi fuel pressure at the fuel rails. Runs great when starting fluid is sprayed up the intake so I have spark I take no idea whats wrong and it's driving me up the wall.
Sounds like you are loosing fuel injector pulse. This is controlled past the PCM. Check all fuses, and then check with a test light that the injectors are getting a signal to fire.
Chevy Berreta 3.1 running rich can't get the service engine calorie-free to get off. I take replaced plugs,fuel filter, regulator egr valve,air filter cleaned port in intake that goes to EGR. Any ideas. Thank you.
If you lot are certain information technology is running rich, the EGR has nothing to do with information technology. What codes do yous have stored. If it is rich and the fuel force per unit area regulator (FPR) did not ready it, then your car probably has a leaking fuel injector.
1998 Pontiac Grand Prix SE 3.1L engine. The car won't pull a hill in the college gear, specially when the motorcar is warm. ( pulls it somewhat improve when cold ). And fifty-fifty on a flat surface, I merely can't take off and throttle as fast I want to. It's a boring acceleration.
Sounds like a possibly depression fuel pressure condition or plugged catalytic converter. Get the computer codes scanned first. May give a management to the trouble.
Problems with a Pontiac Chiliad Am It is just very hard to beginning it sounds like if it is getting to much fuel, considering wen I push the gas half way it get-go. Although it does it with difficulty and for the beginning seconds the engine sounds like it is going to turn of and it smokes blackness. And then it starts to office very normal and dispatch is proficient. Does whatsoever body has any idea what can cause this issue?
Sounds like a leaking fuel force per unit area regulator causing a rich condition. Simply pull the vacuum hose off of it after it has been off for a few minutes and await for gas to come out of it.
I have a 2001 Buick Century press on gas loud whistling no ability after half throttle noise goes away can not get overt 30 mph could it be converter.
The noise you are hearing is the exhaust trying to escape but cannot because your car has a plugged catalytic converter.
2003 Alero 3400. Crude idle, runs fine otherwise. Gas smell in passenger compartment while driving. EGR issue? Fuel injector issue?
A leaking fuel pressure regulator (FPR) or a stuck open fuel injector causing a rich condition and olfactory property of gas in the car.
Chevy Monte Carlo Z34 when the outside temp is less than 50 the cold car revs 5000rpm then dies. This goes on until the motorcar warms up then it runs fine. It runs fine when the exterior temp is over 50. No codes are stored. I take the exact same car and the exact same problem, I have cleaned the throttle body, fuel injectors and MAF Sensor, inverse a broken intake manifold gasket, replaced the IAC, PCV, and EGR valves, and information technology STILL does it. Adjacent matter I'm going to look at, and probably should have looked at sooner is the Intake Air Temperature sensor.
If you have the 3400 dual overhead cam engine (DOHC) then y'all have a lower intake leaking vacuum.
Pontiac Aztec 3400 leaks coolant when the motor is warm dorsum behind the back head upwards by the valve cover behind the alternator at that place is no coolant in the oil but dont leak when the auto is common cold and oasis't been running deceit find or see what would be causing this problem.
The rear head gasket is leaking. You should probably do both since information technology nearly likely has over heated.
Where are the O2 sensors Located on a V6, 3.4L Oldsmobile Alero.
1 is in the rear exhaust manifold, the other is after the catalytic converter.
