Are you getting fuel? Is the fuel pump running? Will it start with starting fluid?

Yes I get fuel. Before it started with the starting fluid, but now with the new pump it starts but when I brake the car will go off? I also put a new relay.

Cranks car but will not start when cold. May offer. Prime the engine through intake with carburetor cleaner and starts. Has to keep rpm up until warms up or will stall. When engine idles properly, did a fuel rail pressure test. Idle pressure 42 psi and 48 psi when remove vacuum line from regulator. Cleaned injector valves and did a bench test. Spray was good. Took car to Honda and did not have an adapter to do a diagnosis. Tried a temperature sensor but did not fix. Figured pulse to injector needed to be longer to apply more fuel. Are there any other sensors to increase injector pulse length or increase fuel to head?

Have the main relay checked. Quite often this relay fails intermittently and when it occurs, the fuel pump is not activated.

Hello, my car will crank, but will not start. Last year I replaced the starter because It was not cranking at all. After the new starter It started fine, until a few months ago. It stopped starting and would only start if I jumped it. Then I took the battery to Autozone to be checked and they said its just fine. Then I checked the oil and noticed it was pretty low and put some more in it started back on its own for about a week. Now It will not start at all, even if I jump it. Just wondering what the issue could be?

Cars need five things to start and run. (1) Gas (2) sparks (3) air (4) compression and (5) all of those being on time. Being that you were able to jump it to start it for a while, I would bet that your fuel pump is the cause of your problems. It was just a little too weak to start, but was able to get enough of a boost when it received a little extra power. But we will check several things.

First, I would check the fuses. I would buy some starting fluid from the parts store or convenience store. Just open the hood, open up the air filter duct, spray some in there (maybe one or two seconds), and then turn the key and see if it starts for a second or 2. try it several times if it does not start the first time. If it starts, or gets close to starting, then that indicates that you have a fuel delivery problem. Basically, you are not getting enough gas, if any.

If that is the case, then I would have someone turn the key on and get under the rear of the car, by the fuel tank, and listen for a humming sound for two or three seconds after turning the key on. If you hear the sound, then the pump is getting power and running. If you hear that, then borrow a fuel pressure tester from AutoZone and run a test. Here is a descriptive how to guide: https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

Start at step 4, in your case.

If, however, you never were able to get it to start with the fluid, then you need to check for sparks. Get a spark tester This is the one that I have: https://www.amazon.com/Lisle-20610-Inline-Spark-Tester/dp/B0002STSC6/ref=sr_1_3?ie=UTF8&qid=1501325755&sr=8-3&keywords=spark+tester. Similar ones are available at the local parts store. Checking sparks is fairly straightforward on your car. Simply unhook the spark plug wire from the distributor and hook up your tester. Then have someone turn the key and see if there are sparks in there. be sure to check all four cylinders.

So check all that and let us know. Of course, if you need clarification, please let us know about that as well.

Thank you for the reply. I have a mechanic here right now working on it and he says it is the fuel pump. So it is being replaced as I type.

My engine will not start. It turns over so the battery and starter are good.
I have spark at the spark plugs. I believe it is the fuel system.
How can I be sure? How do I check the filter and/or the fule pump?

You need to purchase a fuel pressure gauge with a honda adapter in order to properly test fuel pressure.

Do you hear the fuel pump priming when you turn the key to RUNII?

Start by making sure the engine has sufficient coolant. With the engine cool after setting for a couple of hours, remove the radiator cap and fill with coolant. Replace and fill resevoir. Now see what happens. Does it start and then shut off again?

The PGM-FI main relay is the most common cause of this. Remove the relay and resoldering the circuit board should solve the problem.

Hi renell,

Unless your model is equipped with carburettors, otherwise pumping the accelerator does not do much.

You have caused a big misfire and now there are many things that you need to check.

Spark plugs, Distributor, fuel pressure. Isolate the cause then only we can get to solving the problem.

The first thing is to read and record any diagnostic fault codes. If there are none in memory, you'll need a scanner to view live data while driving to see if a sensor signal drops out just before the stalling occurs.

The most likely suspects are the crankshaft position sensor and the camshaft position sensor. They often fail intermittently by becoming heat-sensitive, then they work again after they cool down for about an hour.

Contacts on fuel relay under dash is opening and closing. Removed test plug for fuel, no fuel. Rapped on gas tank with two by four while cranking engine, it started. Replaced fuel pump, it started. A day later same problem, no fuel to engine. Have not put a gauge on fuel line yet or replaced filter. But after cranking the engine and pumping gas pedal it started. Any idea besides filter?Thank you
