1999 Buick Lesabre 3800 how do I check for Intake Manifold coolant Leak?
the spark plug tips will look , LIKE A HORRORon the offender cylinder. there is one good sign and USA ? car, the OBD2 scans show the leaking cylinders are gross misfire DTC error P030x where tells witch cylinder is getting wet. (called misfire)the bank leaking OBD2 fuel trim way off the scale. radiator leak down test Fails. (a tool with same name) first off the gasket would have to be a double failure to leak to intake runners, water side to air side there are 2 parts, here the plastic top and aluminum main bottom intake manifold. evidence 2 if the gasket leaks below the HLA Lifter area gets wet . and the engine oil looks just like chocolate milk shake. nasty oil , MILKY for sure. if the wet ports fail water hits the pan too. also is not the upper plastic side, dry. and only bottom is coolant wet. see my threat vector photoas you can se , it be a double failure of the gasketif sucking oil see white smoke at tail pipe endor see steam from water (coolant burned) same place.
2004 jeep grand cherokee died on the freeway and now just cranks but won't start
Whew! Tight spot. Here are some quick and some more involved things to check. Hopefully, another responder will pitch in. A good time to call AAA.
Troubleshoot this issue step by step:
Check for Spark: Crank the engine and check if there's a spark at the spark plugs or ignition coil. If you have a spark, the crankshaft position sensor (CPS) is likely not the problem.
Fuel Pump Operation: When you turn the key to the "on" position (but not start), you should hear the fuel pump run for a couple of seconds. If you don't hear it, there might be an issue with the fuel pump or its relay.
ASD Relay: The Automatic Shutdown (ASD) relay controls power to essential components like the ignition coils. If the ASD relay is faulty, you won't get spark. Check and replace it if necessary.
Throttle Position Sensor (TPS) and Intake Air Temperature (IAT) Sensor: Ensure that these sensors are functioning correctly. They play a crucial role in engine performance.
Check the Key: If everything else checks out, consider the key itself. The chip in the key has a unique identifier code. Some replacement keys may mimic this code, so make sure your key is genuin..
Bus Line and SKIM Module: Verify the PCI bus line between the PCM/data link connector and the SKIM module. If there's an issue with communication, it could prevent the engine from starting
Sirius SU5 Kichen exhaust fan, does it have a fuse or overload sensor
The Sirius SU5 Kitchen exhaust fan does not have a fuse or overload sensor. However, there are a few things you can check if you're experiencing issues with the fan:
AIR System: The Sirius SU5 exhaust fan is part of the secondary air injection (AIR) system. When the AIR system is inactive, the closed AIR control/shut-off valve prevents air/exhaust flow in either direction. If you suspect an issue, you can find the AIR PUMP fuse (usually labeled as #64, 60 amps) in the under-hood fuse box. Try pulling the fuse to see if the fan stops running. Additionally, there are two relays related to the secondary AIR pump: the AIR injection (AIR) pump relay. Check if the relay contacts are stuck together.
Cooling Fans: If the fan is running continuously, it might be related to the cooling system. Check if the cooling fans are coming on as they should. Inspect the fuses and relays associated with the cooling fans.
Temperature Sensors: Ensure that the temperature sensors are functioning correctly. Faulty sensors can cause issues with fan operation. For example, codes like P0481 refer to coolant temperature fans circuit malfunction, which could be related to wiring, the fan itself, or the ECM.
2013 Cherry Tigo 2.0 TXE loose power when driving and come to a standstill. Engine cranked but does not start. What can be the problem
Try to diagnose the issue. That said, a professional mechanic with the diagnostic tools is likely needed.
Restart the Vehicle: First, shut off the engine, wait for about 10 seconds, and then restart the vehicle. Sometimes, this simple reboot can reset any signal errors that might be causing the "reduced engine power" warning light. It's still a good idea to have a mechanic check it out.
Since you've already changed the battery, it's essential to ensure that the new battery is functioning correctly. Check the battery connections, terminals, and cables. Also, inspect the electrical system for any loose or damaged wires.
Fuel System: Verify that there are no fuel-related issues. Ensure that the fuel pump is working correctly, and there are no clogs or leaks in the fuel lines.
Ignition System: The ignition system plays a crucial role in starting the engine. Check the spark plugs, ignition coils, and ignition control module. Faulty components in this system can prevent the engine from starting.
Air Trapped in Cooling System: As suggested in one of the solutions, make sure there's no air trapped in the cooling system. Bleeding the air out can help maintain proper engine temperature and prevent starting issues.
Remember that driving with the "reduced engine power" warning light on is not recommended.
Engine Malfunction, starter pulley jammed.
All questions in Cars and Trucks need 'year make model' please.But this could be a generator, chainsaw, leaf blower or mower in which case 'make model (what is is).On a vehicle, remove sparkplugs and try and turn the engine by hand using the big nut on the crankshaft pulley. Broken timing chain or belt and the piston is hitting the open valves. However, NO cars have a starter that has a belt, they are gear driven...
On my Fortress 2000 the turn signals not working every thing else works
this is no car it is Mobility scooter , right? electric scooter. tiny.
be does the hazard switch work right or not. test 1
test 2 all fuses good
now working means what?
all 4 or more turn lamps dead.? or stuck on, or some work or not?
only left or right or only front or rear fail?
this answer is for cars, posted to cars. and trucks.
test 3, remove all bulbs and test them 1 by 1, in the car. (lamps can in fact short out)
02 MONTE CARLO LS When I turn the key to the ON position, if the turn signals do not flash the starter will not engage.
3.4L or 3.8L not told.
hot wired the starter solenoid you meant (a SOP act that) all techs do. and good input if yes.
when it failed to crank the next act is SCAN the PCM and let it tell you why it blocks cranking
I sure will. OBD2 scan tools any.
we check all fuses next. be a shame if 50 cent ATC fuse is cause.
Battery voltage does not drop below 11vcd cranking, 12.6v is charged (rested voltage)
well if the starter is dead fix that first, and the automatic trans, blocks the cranking , to the starter
if the car has bad PRNDL switch (fails in park) or alram in the cluster is active is it?
blinkers are last, you can still hand signal by law so fix the starter first.
no need to blink if can't drive or worse stranded with dead starter , how fun is that>?
Chevy. (no starter or GEN replacements right? with battery still connected. sure. not done wrong
the starter runs by the CRANK relay.
under hood relay and Logic runs its coil inside said relay via, BCM etc.
PCM crank fuse not blown.at N/M 11 slot.
the key switch at start , sends 12vdc to CRANK FUSE and that goes to PCM.
the PCM is told to crank, the start.
the car has tranny park cable if not calibrated, or bad, park does not happen and PCM sees that
and will not crank the car with P/N switch showing wrong.
4T65t transmission must be fully in to park and not failing P/N switch
not scanning the PCM first you miss all these facts.
if you have the M/T box now is the time to fess up. really.
here is the PCM connection to the A/T box
the signals are GGGG or 0000 volts DC.
if not the PCM block all cranking
if you scanned the PCM you'd already know this.
the PCM is smart to know that ******* codes from the switch must set a DTC error.
as you can see that it is 4 times safer to not to drive over the kids.
amazing no?
