I'm sure you have installed a fuel pressure gauge and monitored the fuel pressure while the problem is occurring?Another diagnostic tool which is easy to do,is while the problem is occurring,unplug one sensor at a time beginning with the Mass Air Flow first,.if it uses one.Many times,not always,depending on the sensor,if the sensor is taken out of the picture as far as what the PCM is seeing,like unplugging the MAF,the PCM will substitute the missing sensor output with a generic value that will allow the engine to at least run,and if unplugging for example the MAF,the engine idle speed returns to normal,you know you're onto the problem.You didn't mention if the engine ran ok other than the idle problem.As far as checking for vacuum leaks,i use something like brake cleaner or WD 40,more of a liquid,and it does sound like a vacuum leak.Plastic intake manifolds do develop nearly invisible cracks that open up more with heat.Revsisit the possibility.And as for the PCM,it is possible,but more likely a mechanical problem.Lastly,remove an O2 sensor or two before the catalytic convertor,run the engine and see if anything changes.Cheap way to verify the catalytic convertor is flowing and not restricting engine airflow,as i have seen bad cats cause misfire codes and strange problems.Good luck.

SOURCE: 82 corvette crossfire injection, engine

Please go to the crossfire injection forum to get some straight answers to the 82 corvette CFI system and how to troubleshoot it properly. There's a lot of misinformation given here, so much so, I don't know where to begin.

One thing is, the 82 corvette CFI does NOT have a MassAir Flow sensor system, it uses MAP and O2 mostly. The CTS sends a signal to the ECM telling it what the temp of the motor is and in turn the ECM controls the amount of fuel being dumped. On the older (orignal) CTS sensors, they have one wire and takes its ground from the threads. If any coorosion takes place, usually the CTS will report a cold engine and request lots of fuel.

To repair this issue, install one of the newer style CTS sensors that have two wires, one for signal and the other is ground.

Fuel pressure and vacuum leaks on any CFI motor play key roles. Set the FP to 14-15psi measured inbetween the TBs. The regulator is located on the rear TB and must be slightly moded to make it adjustable and can be done in a few minutes.

SOURCE: car wont start

check your fuel pressure it should be 35 psi .fuel pump relays dont go out but check all fuses with test light there is a fuel injector fuse but most likely problem is your fuel pump!

SOURCE: Fuel injectors leak at fuel rail

Get some new O-rings, and this time put oil on them before you insert them into the fuel rail. The regulator is alright.The problem is that the o-rings can roll up, or twist when push em in dry. Had this problem once, easy fix, but was frustrating.

Your Jeep has what's known as the delayed start, no check engine light problem. The Jeep will not start until the check engine light comes on, on the dashboard. Next time it cranks but will not start, look at the dashboard to see if the check engine light is illuminated. If it's not lit up, then your Jeep does have that problem and your Jeep ecu is in need of repair or replacement. There are components inside the ecu that are going bad and will continue to get worse, eventually leading to a permanent no start condition. There are ecu repair services and replacement ecus on ebay.

Not uncommon for Ford focus coil packs to play up I've replaced a few I would recommend, replace coil pack and have leads. If you have car serviced at the regular service interval the plugs should be ok.

How do I remove door interior to access the door lock mecanism ? on both door !


You will need a Torx head screwdriver.
First, disconnect the battery and leave it disconnected for several minutes because you don't want to lose a finger in the window mechanism or have the air bag blow up in your face.
Next, starting from the rear, carefully pry up the trim strip that runs from the door latch back to the back of the door. It is usually wood-grain finish, but may be aluminum or carbon fiber, depending on your interior package. Remove the screws beneath that trim.
Pop out the two oval plugs from the underside of the door handle, and remove the two screws beneath those plugs.
Now with something large and flat and preferably with no sharp edges, start snapping the inner door panel off. If you break some snaps, no worries. They are available on line for $0.35 each or at the dealer for about $1 each. The top of the door panel does not hook in the window sill like most cars, it snaps straight out.
Now disconnect the speaker wires, mirror control, and probably the air bag. You can leave the air bag connected if you are willing to work around it.
I presume that your window regulator is broken. Specifically, the piece of plastic that attaches the window mechanism to the cable. You can replace the whole regulator, but on my wife's '04 330i, I chose to put two good quality zip ties around it. One just above the broken piece and one just below it. There are holes and notches in the metal backing plate that work great to hold the zip ties in place. I did this repair a couple of years ago and the window still works just fine. Much quicker and cheaper than replacing the whole regulator.
If you unplug the air bag, DO NOT connect the battery and turn on the key to check your work while the air bag is unplugged. Doing so will set a critical fault in the SRS system that only a dealer or well-equipped BMW repair shop can clear. DAMHIK

Check the fuel pressure regulator,and the fuel return line all the way back to the fuel tank,one ,or the other is stopped up,or the fuel regulator is closed up.I would check the fuel return line first,this is the most likely problem.

The fuel pump is not pumping the fuel.


Is the fuel pump actually coming on??? If it isn't, I would start by checking for a fuel pump relay.  This is usually located up in the engine compartment in a black box on the drivers side.  Relays are small black boxes approx 1"x1".  These have a tendency to go out just like fuses.  Also double check your fuses.  If you suspect a that a relay is bad, you can interchange them with other relays that look the exact same to see if they really are the problems.  These relays are very quick and easy to change and are very cheap.  They usually run no more than $10-15.
Any further questions, feel free to ask.
