Acura Integra Doesn't Start

Acura wont start?

These are some of the most common no start problems with Acura Integra Vehicles from Most common #1 to least common #6.

Most common:

1. Distributor igniter and Coil Built in (Most common)
2. Ignition coil
3. Igniter
4. Crankshaft Position Sensor (CKP sensor)
5. Distributor Wiring Harness
6. Ignition Switch

No Start issues usually boil down to 3 seperate areas

1. Spark, which is Ignition system related could be a component, wiring, etc
2. Fuel which has to do with gas delivery to the engine: Electrical, mechanical, simply running the vehicle out of fuel
3. Engine Compression which is the pressure the engine needs to develop internally in order for the fuel to burn. Faulty timing chain, broken timing belt
4. A plugged/restricted exhaust can also cause a vehicle not to start

 

 

The first step for diagnosis:

1. Make sure the battery is fully charged.
2. Make sure you have spark to the spark plug.
3. Make sure there is fuel getting to the engine
4. Make sure you have good engine compression

The battery test if pretty obvious if you turn the key and hear nothing chances are good the battery is dead. Make sure you have a sufficiently charged battery, to test this try jump starting with a known good battery, if battery is okay with a known good battery, charge the battery, and test the charging system.

Make sure you have spark at the spark plug. The easy way to test this is to remove the plug wire from the spark plug end and place a screwdriver inside, hold the screwdriver about a quarter inch away from ground and have someone crank the engine over, if you see a strong blue spark jump to ground, you have spark, more than likely ignition is good. Be careful some ignition systems produce alot of voltage.. Make sure no fuel leaks. Be safe.

The easy way to test if this is a fuel problem is to is too add fuel to the engine. Use a no starting fluid, that is best and can be purchased at any parts store. Spray it into the air intake if vehicle starts you have a fuel delivery problem.

Lastly, check that there is engine compression. This is done by removing the spark plugs, inserting a engine compression into the spark plug hole, cranking the engine and recording the reading, should be approximately 120 psi on the guage, dont just check one check all cylinders.

94 acura legend has a hard time starting in cold weather?

I just bought a 94 acura legend. It is about 10 degrees in the morning here. when i start it up it sounds like its going to give out on me soon. I don't know if its the cold temp or what? It does start but by the way it sounds, it seems like something is weak. It starts on the first try but It cranks for longer than normal, but eventually it starts. Should i be worried?

No worries, this is normal. The engine on the Legend will take a longer time to start in cold weather. haha it simply doesn't like the cold much. However, start it in warmer weather, such as 50 F/10 C, and see if it is making the same problem. If it is, you have a main relay problem. And that simply requires some soldering. Those engines last for a LONG time. Except the head gaskets are particularly weak on them.
