Question about 1994 Toyota Corolla

1 Answer

Fuell injector problems

Due to the excessive overheating of the car due to a burst radiator, I think I have damaged the fuel injectors in that the car is not idling consistently and when excelerating, it seems to hold back and then let go and could this also be the cause for the "Engine Management System" light to burn? What can I do to rectify the problem or do I have to take the car to be put on a machine to check the car computer settings and/or fuel injector performance?
Regards,

    I would doubt that the injectors have failed. I repair overheat conditions every day, and rarely replace injectors.



    I would get the car scanned on a diagnostic tool, and then get the codes back to us. With the codes, we can better diagnose and rectify your condition.

Why is the engine emmitting black smoke when driving


black smoke is excessive fuel in the air fuel ratio
causes leaking gaskets under injectors, problem HO2S sensor , blocked air inlet /filter, excessive fuel pressure
possible cause --mechanic did not use new gaskets under injectors that were damaged form the overheating

Excessive black smoke puffs out when I take off or try to pick up speed. Is it the turbo or injectors that need replacing


I'm suspecting it is a diesel you are reffering to. Excessive black smoke is due to unburned fuel. You may have an injector issue where one or more is leaking. Very doubtful as to a turbo problem causing this. I would suggest a strong diesel fuel treatment in the fuel be tried first ( possibly several applications ) to see if it helps. Injector replacement is expensive

How do i ck if fuel pump defective or no pulse at injector no power.


If you have fuel coming out of the lines when you are cranking the engine then your fuel pump is working. You should only get a small burst of fuel when you first turn the key on and then nothing while the key is on, the ECU only tells the fuel pump to turn on when cranking and when it can see cam and crank sensor signals while the engine is running. The small burst of fuel you may or may not have experienced is only to prime the fuel rails. To test your injectors, you can buy what is called a "noid" light. They have them at most stores that have a good tool/automotive section, such as sears. You unplug one injector with the engine off, plug the noid light into the injector connector (harness side going to injector). Then start or crank the engine over and see if you can see the light pulse on and of very fast. You may need two people due to limited visibility while cranking the engine. Repeat this for the rest of the injectors. If you have an "ohm" meter, you can ohm check the injectors by disconnecting each one and touching the pins inside the connector cavity on each injector. The ohm reading should read between 5-20 ohms. I hope this info helps!

?€¢
Vacuum hoses for splits, kinks, and improper connections


?€¢
The air duct for being collapsed or restricted


?€¢
The air filter for being dirty or restricted


?€¢
Objects blocking the throttle body


?€¢
Excessive fuel in the crankcase due to leaking fuel injectors--Refer to Fuel Injector Diagnosis .


?€¢
The evaporative emissions control system for improper operation


?€¢
Excessive fuel pressure--Refer to Fuel System Diagnosis .


?€¢
Malfunctioning fuel injectors--Refer to Fuel Injector Diagnosis .


?€¢
Fuel contamination--Refer to Alcohol/Contaminants-in-Fuel Diagnosis .


?€¢
Fuel composition--Refer to Fuel Composition Diagnosis RPO LGD, VIN code W, E85 compatible engines only.


?€¢
The HO2S sensor 1 for improper installation and for electrical wires or connectors that may have contacted the exhaust system


?€¢
The HO2S sensor 1 signal circuit shorted to voltage

I have a 2002 Jaguar X-type. The check engine light came on and it has been acting jumpy/shaky. I recently took it to be diagnosed and the codes I recieved back were P1314, P1316, P1111, and P0302..What do...


All fault codes can be checked out at http://www.bluejag.co.uk but here are the results for some of yours. You can ignor P1111. Looks like a faulty plug or coil pack cylinder 2

Fault Code:- P1314 Indicates a Power-train fault


The fault is generally due to a problem in the Ignition or Misfire area


Fault Description: Misfire rate catalyst damage -bank 2 NOTE: This DTC will flag only when accompanied by an individual cylinder misfire DTC: P0300 - P0306

Action of ECM:- ECM Default:- Maximum engine speed reduced


After clearing the DTC, complete the Misfire monitor drive cycle
Check for a reoccurrence of fault DTC.


Possible Fault:- Cylinder compression low Worn camshaft / broken valve spring(s) Fuel delivery pressure (low / high) Fuel injector(s) restricted / leaking Fuel injector(s) continuously open Fuel contamination Fuel injector circuit fault(s) (Injector DTCs also flagged) Spark plug failure / fouled / incorrect gap ECM to ignition coil primary circuit fault (Cylinder misfire detected DTC also flagged) Ignition coil failure
Fault Code:- P1316 Indicates a Power-train fault


The fault is generally due to a problem in the Ignition or Misfire area


Fault Description: Misfire excess emission NOTE: This DTC will flag only when accompanied by an individual cylinder misfire DTC: P0300 - P0306

Action of ECM:- none


After clearing the DTC, complete the Misfire monitor drive cycle
Check for a reoccurrence of fault DTC.

Engine miss


if you have only one cylinder getting that excessive fuel it indicates that the computer thinks that that cylinder is not sparking and thinks no fuel is the proble. this is due to a timing issue. even though you replace the injector which was most likely not the problem to begin with. in order to get spark the coil has to energize you more than likely have a bad coil pack.replace the coil and your miss will no longer exist.
