Question about 2004 Chevrolet Cavalier

2 Answers

2004 Cavalier with 2.2 echo keeps popping #3 fuel injector. EVP solenoid has been replaced as well as fuel filter.

All fuel injectors have been refitted with new o-rings and #3 was replaced with new one. Gas smell and leaking after it pops out of rail. What can the problem be? It has been to a shop.

If they were removed before make sure there is not a old o-ring still in there not letting it seat properly.

If plug an plug wire has been replaced , an dist. cap an rotor an problem is still there ,maybe a fuel injector problem .
Perform the fuel injector coil test. Refer to Fuel Injector Solenoid Coil Test .
A fuel injector coil winding resistance that is too high or too low will affect engine drivability. A fuel injector control circuit DTC may not set, but a misfire may be apparent. The fuel injector coil windings are affected by temperature. The resistance of the fuel injector coil windings will increase as the temperature of the fuel injector increases.
Diagnostic Aids
?€¢
Monitoring the misfire current counters, or misfire graph, may help to isolate the fuel injector that is causing the condition.


?€¢
Operating the vehicle over a wide temperature range may help isolate the fuel injector that is causing the condition.


?€¢
Perform the fuel injector coil test within the conditions of the customer's concern. A fuel injector condition may only be apparent at a certain temperature, or under certain conditions.

  1. Disconnect the multi-way harness connector of the fuel injectors.
  2. Measure the resistance of each fuel injector between the ignition 1 voltage circuit and the fuel injector control circuit, at the multi-way connector with a DMM. Refer to Testing for Continuity in Wiring Systems.
  3. Record each fuel injector resistance value.
  4. Subtract the lowest resistance value from the highest resistance value.
Is the difference equal to, or less than, the specified value?
3 ohms

My 2004 mazda 3 wont rev properly and lack of power especially mid rev range


If the spark plugs have a lot of miles on them that would be a good thing to change out. Also check for air leaks in the intake system. The EGR plumbing can get crusty and crack after a lot of miles. You may have some clogged injectors that would benefit from a couple bottles of injector cleaner in the tank. If you have a CEL light, stop by an auto store to get the code scanned.

Fuse to my fuel injector is popping and my car dies


It could be a short in the injector circuit (and it's not that complicated), or it could be a shorted injector itself. You may be able to isolate and find it.
Begin by disconnecting all six injector connectors from the injectors. Now put a new fuse into the injector fuse slot and turn the key to on, not start. If the fuse blows again, there must be a short in the circuit-I'll get to that later. If the fuse stays good, then put one injector connector back on -key still on. Watch for the fuse to blow when you connect each individual injector back on. If you have a shorted injector (internally bad), it can blow the fuse and stop the injector power circuit. That injector must be replaced. The injectors can also be checked with a volt ohm meter, if you have one.

So if your circuit is bad, from fuse to the injector harness connector a pink/black wire supplies constant battery voltage to all injectors-always hot in run or start-each injector gets a splice from this pink/black wire. The other wire at each injector is the dark blue ground wire. From each side of the engine the ground wires splice together-so 3 to each side-and head into the ecm on the 22 pin blue ecm connector. The pin numbers are D3 and D9. When the computer internally grounds one side or the other for a split second, that is where you get the pulse-the injector solenoid is energized, opening the injector for fuel to spray out. So now you know where all the injector circuit is, and where to look for a short. Having a DVOM would help you immensely in troubleshooting any thing automotive. Good luck, let me know what you find.

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

Troubleshooting the no-start condition - from the 1990 Mitsu Mighty Max Repair Manual:

Priority Action Part Type -- Cause
1 Inspect Battery -- Battery Discharged or Faulty.
2 Inspect Battery Cable -- Corroded, Broken, Shorted or Poorly Connected Battery Cable.
3 Inspect Distributor Cap -- Distributor Cap Cracked or Burned.
3 Inspect Fuel Filter -- Clogged or Dirty Fuel Filter.
5 Inspect Ignition Coil -- Faulty Ignition Coil.
6 Inspect Wireset -- Worn, Damaged or Faulty Spark Plug Wire(s).
7 Inspect Spark Plug -- Incorrectly Gapped or Fouled Spark Plug(s).
8 Inspect Starter -- Starter Motor Faulty.
9 Inspect Fuel Pump -- Low Fuel Pressure.
10 Inspect Solenoid Switch -- Faulty Starter Solenoid Switch.
11 Inspect Fuel Pump Relay -- Faulty Fuel Pump Relay.
12 Inspect Fuel Injector Pressure Regulator -- Faulty Fuel Injector Pressure Regulator.
13 Inspect Ignition Switch -- Improperly Connected or Faulty Ignition Switch.
14 Inspect Starter Drive -- Faulty Starter Drive.
15 Inspect Fuel Injector -- Dirty or Worn Fuel Injectors.
16 Inspect Fuel Pump Strainer -- Clogged or Dirty Fuel Pump Strainerat.
17 Inspect Engine Control Computer -- Incorrect Operating Information Being Delivered and Sent From The EEC.
18 Inspect Fuel Tank -- Fuel Tank Empty.
19 Inspect Carburetor -- Carburetor Flooded or Faulty Choke.
20 Inspect Distributor -- Worn, Loose, or Incorrectly Installed Distributor.

Code p1349 in toyota echo 2004


Under certain conditions customers may experience a MIL "ON" condition with DTC P1349 indicating a variable valve timing (VVTi) malfunction. In some cases, the cause of this DTC may be the VVTi actuator.

In general P1349 is a misfire or ignition issue under most general OBD-II - but Toyota spec'd OBD-II has it as a VVT malfunction. Unfortunantly - hard to tell which it is. Might be the ignition timing set too advanced (VVT-i issue) or low fuel pressure (bad or clogged injector, bad or low flowing fuel pump/regulator). An emissions test could tell you which one it is. If you want to try a quick fix on your own, I'd start with the basics, change the spark plugs, air filter, and maybe the pcv valve, all these are cheap and easy. Other things could cause the problem though, so if the quick fixes don't work, I'd lean toward the injectors.

Seafoam and other additives are very good solvents that can help clean the injectors - but may not be strong enough to clean off these injectors. Injector cleaning services generally don't work that well - best way is to have these cleaned ultrasonically or replaced (very costly).

Depends, injectors can be cleaned for far less than replaced. I had the same thing happen in my Dodge truck all 8 injectors pulled cleaned replaced. Gave me the same song and dance about tank, ended up not doing tank and just having a large (from a marine store) in-line filter installed. Have had no further problems 60,000 miles later still going strong and haven't had to replace the filter. The injector cleaning was $35.00 each plus about $10.00 each for them to remove and replace. The filter cost just under $200.00 and they charged me $150.00 to install, With everything I was out the door for around $800.00.

Diesel fuel injection fault light keeps coming on , loss of power black smoke from exhaust.


Black smoke usually means a fuel problem, try changing the fuel filter and get an injector cleaner from tesco's or asda they're about £3 to£5, if your gonna change your fuel filter you might as well change the oil and filter and the air filter at the same time
