Check to make sure the fuel pump is working. On the fuel rail there is a test port that you can connect a mechanical gage too. Also there is a fuel cut out switch under the dash closer to the floor that has a reset button on it. If you hit a very hard bump it can trigger the cut out switch. It is designed so that upon impact in a collision it cuts the fuel supply to the engine to prevent an engine fire from leaking fuel. Sometimes these switches go bad, But, try the reset first and be sure to check that the fuel pump is working.

Would a bad oil pressure switch cause a no start on a 98 b2500


Hi,
Symptoms of a bad or failing Engine Oil Pressure Sensor
  • Oil Pressure Light comes on, and you check the engine oil level, But oil level is okay, you can blame the false reading on the sensor.
  • Oil Pressure Light blinking constantly. This is the normal >check< oil pressure sensor Warning that the sensor is going out.
  • If the sensor is giving false readings, Dispite oil level, the sensor could be replaced.
If the Sensor is currently not working, and does not warn you of engine oil level, and oil level gets extremely low, The Engine could burn up/stall due to lack of oil, and may not restart.
Then you could probably blame it on the sensor.
But really would be lack of oil.

Intermittent No Start,
Common causes deal with 3 basic systems/areas of engin
  1. Compression, its the build up of air and fuel into the engines cylinders. Then is compressed by the pistons. And is under pressure. FAILURE An Air leak (vacumm leak) will allow pressure to escape.
  2. Ignition System, good battery, good relays, wires are not loose or disconnected, good 10volts to starter, 10volts to distributer>gives 20kvolts to spark plugs>has strong spark to ignite compressed air in cylinders. Other sensors need to work. Crankshaft sensor(ccs) Throttle Position Sensor(TPS), +more
  3. Air/fuel Ratio, Air Intake Manifold, and Fuel Pressure Sensor *Fuel Injection Pressure Sensor---if car is fuel injected*, air filter is clean and intake manifold hose, Throttle Plate Acuater, Idle Air Contro Valve(IAC). Also vacumm leak cause no start. To much air not enough fuel will cause lean fuel mixter==low power, low idle, no start.......To much fuel not enough air will cause rich fuel mixter==too much fuel could cause engine knock, flooding of engine wet spark plugs, No Start
Scan Vehicle computer for Codes, Places like AutoZone---Discount AutoParts will connect scanner for free, And Code Will say What is wrong with Vehicle,

Car and Light Truck Engine Stalls-all fuel injected gas engines


Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

What is the code 171 mean on my dodge ram 1500


P0171 Chrysler - Fuel System Lean

Possible causes
- Intake air leaks
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection

Tech notes
If the P0171 is combined with the P0174 code, it's very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replaced the air filter and clean the air flow meter. If the problem persist the front oxygen (O2) sensor may need to be replaced.

When is the code detected?
- Fuel injection system does not operate properly.
- The amount of mixture ratio compensation is too small. (The mixture ratio is too lean.)

Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Excessive Fuel Consumption


P0171 Chrysler Description
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. The Engine Control Module (ECM) calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.

In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the ECM judges the condition as the fuel injection system malfunction and light up the Malfunction Indicator Light (MIL) (2 trip detection logic).

- Ignition misfiring

- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection Tech notes The codes is usually set when there is an intake leak after the air flow meter, before replacing any parts check for loose or broken hoses and intake gasket leak. On Ford some models dirty air filter, and dirty or faulty air flow sensor are the cause of the problem.

It's a very common problem for the Ford Windstar. Here a link to a web site with information how to repair:

99 ram with 5.2 wont start, good fuel pressure on rail, good spark. no engine codes any ideas


You have fuel pressure but is the fuel being injected? Do this, get a can of spray starting fluid from the parts store or a hardware store, spray into the engine air intake, if the truck starts and then stalls out you have no fuel being injected. Also make sure when the engine is cranked that the engine computer (ECM) is getting power, you could have a problem with the starter motor switch, this is the electrical switch the ignition key actuates.

Year 2001 XG300 P0115, P1159, P1191, P1193, P0115


P0115 - Engine Coolant Temp Sensr - open/short
P1159 - Variable Intake Motor Malfunction

P1191/P1193 Limp Home Valve - Low RPM

First, clean the throttle body and check for anything which might obstruct AIR FLOW to it.

The P1159 is the Variable Intake Motor Malfunction. this motor is either 'OPEN'... or 'CLOSED' position. It is located on/in the intake manifold (plenum) and is only opened when cruising... it is closed at idle. If it sticks 'OPEN' is can cause drivability issues.

The car keeps on stalling when i stop or it idles


needs fuel injection service,try this take air intake hose off while the engine is running buy some carbarator cleaner spray it into the intake while you push on throtle and then put it back together take it on the freeway for 2 miles see it has inproved,also try the lucas fuel system cleaner it goes in the gas tank it works good
