This is a 1992 Accord AEX. I bought car sitting in field. Replaced coil distributor, main fuel pump relay and new fuel pump. The fuel was laquer so presuredwashed fuel tank out and blew air throught fuel lines. Car started and runs like a cylinder isn't working. I'm thinking injector? because of the dirty fule sitting in it for so long. What should I do to see which cylinder isn't working? How can I test injestor?


THANKs!!!

 

Since the car sat for a long time, I would replace the spark plugs, distributor cap, and distributor rotor.

Inspect the spark plug wires for cracks in the insulation. You can also spray a fine mist of water at night on them. If you see arching, then replace the spark plug wires.

 

Everything is new. I think I have it narrowed down to #4 Cylinder. I checked it and it has spark? but when I take #4 wire off car runs the same, so I think it's Cyl. #4 maybe no fuel?

 

Measure the resistance across the two pins of each injector. They should all be close.

You can hook a 12V test light across the plug to the #4 injector and start the car. It should flash indicating the ECU is grounding it.

Compression test on each cylinder would identify a leak in compression.

 

put the blade end of a screwdriver on the # 4 injector and the other end in your ear,, listen if the injector clicks,,

If it does ,,, next step is to chk compression

If it does not,, tap the injector a few times with the screwdriver ( some times they stick ) ,,,,,,if still no click then you got chk for injector pulse ,,,,,,,,,,,,if pulse is available you got a bad injector ,,,,
Also ,,,is spark plug ok ???
chk this and let us know ..

 

Took compression test 190, 184, 178, 178

Checked firing order found problem my nephew had 2 wires crossed. Running much better.

Seems to idle kind of high? and takes a minute to come down. sometimes you has to gas it in order for idle to drop?

 

Clean throttle body and both sides of throttle plate using throttle body cleaner and an old toothbrush. Clean out IACV using throttle body cleaner.

On a cold engine, bleed any air out of the coolant system by opening up radiator cap, then loosen bleed valve on thermostat housing. Allow air to spit out. Close valve when steady stream of coolant comes out. Top off radiator.

 

It works!!!

Thanks for your help!
