94 LX Accord

Was cleaning my buddy's accord with him, he cleaned the engine bay, sprayed it down while the motor was running, no problems, he then drove it around the block a few times, parked it, shut it off to wash it. Tried to start it again and it wouldn't go. It's trying to turn over, but just keeps cranking, and we get alot of backfiring.

Tried to bump start it, didn't work, so we just got back from pushing it up the hill, I'm guessing it could be water in the plug valleys? Anyone have any idea?

 

not much help but let everything dry, and next time spray some Simple Green on then spray it down with the hose and let it dry, don't drive it. g/l

 

something could have went wrong with the starter due to the water? and were there any problems with it not starting before it was washed or the problem just came up?

 

Nothing was wrong before the wash, but sometimes things like this are pure coincidence. He has compression, we tested the spark plugs for spark, and we put a couple gallons in the car just in case.

Now we're thinking maybe the fuel pump? Fuel pump regulator?

 

Did you pull the cap off the distributor?

Have you checked for spark and fuel?

EDIT: Ok sorry didn't see you checked spark...

main relay?

Haven't taken the cap off yet, what would we be looking for?

I'm gettin tired i missed that part were you checked spark, try tapping the main relay while trying to start or listen for the fuel pump to prime when you turn the key on...

Where is the main relay located in this car? We could hear the fuel pump priming, and we checked the fuel pressure valve on the fuel rail, it sprays fuel when we try to start the car.

 

You said you already checked your plugs, then the chances are your cap and rotor could have gotten wet and white stuff (calcium) built up with water seeping through. I would check that before anything else. Also check your oil and make sure no water get in it through the plugs.

 

Take a hair dryer to all of the electrical connectors for the distributor, TPS and MAP sensors. there could be water in there causing a false signal to go to the ECU. Throwing the timing off.

Check to see if there are any DTC's stored on the ECU. You may have a code on there that could point you in the right direction. Jumper the SCS connector under the glove box, turn the ignition to the ACC position and make note of the long and short flashes. If the CEL stays solid then there are no stored codes.

Is there any thread explaining in more detail on how to do this?

 

water in the dizzy. spring wd40 in the cap.

Checked it last night, there's no water in there. We should spray wd40 in there anyway?

 

There should be a blue connector under you glove box that looks like this.


Remove it from the mount that it is in under the glove box.


With the ignition off insert a paper clip clip or piece of wire bridging these two connectors.


With this connector shorted turn your ignition to the ACC/II position (engine not running) and watch the CEL for flashes. long flashes = 10s short flashes = 1s for example long...long...short...short...short...short would be code 24.

There may be more than one code stored on the ECU at one time. If there is more than one there will be a pause between them

Example long...long...long..short...short....(2-3 second pause).....long...long...short...short...short...s hort = codes 32 & 24. There can be more than two codes as well. I'm not 100% how many the ECU stores at one time but it will flash them all with pauses in between.

 

Wow dude, thanks for the info. Where can I find a reference chart for all of the fault codes?

 

We went out and tried that. There were two plugs plugged into that blue thing, one with 3 holes and one with 2, like the one you showed. We bridged the one with 2 holes, turned the key to II, and all we got was a solid CEL. Does this mean anything? Why won't it work?

 

It has no codes stored. If you crank the engine and pump the accelerator a couple of times, then remove a plug, is it wet with fuel? Do you smell the unburned gas inside the cylinder? If so, there is no spark to ignite the fuel. If the plug is dry, there is no fuel for the spark to ignite. This will at least narrow it down to either a spark or fuel related issue.

 

We pulled the fuse for the ECU for a minute to let it reset, still nothing but a solid CEL when we bridge the connectors.

Okay. So what could be wrong with the car, if it has spark, compression, and fuel and it's not throwing any codes?!

 

Read my edited post above, please.

We pulled a plug and held it against the block, and we had spark.

 

If you had just tried to start the engine, the plug should have been wet with gas. If the plug was not wet, I think your fuel injectors may not be working. Maybe try drying those wires, and checking the connectors.

 

You could have a main relay issue. Here's a very helpful link on main relay. Good luck. Read the other symptoms and causes down the page.

After reading that, it sounds like it could be flooding?

 

Maybe the pressure regulator is not working right. Just guessing here. I would save that link if I were you. It may come in handy in the future. Good luck solving your problem.
