1999 Honda Accord No Start (case study)
For more on Engine Performance Diagnostics go to my website at
I am doing field work in this video on a 1999 Honda Accord with an
intermittent no start complaint. Other symptoms include: stalling, long
crank times, surging, bucking, poor transmission shifting.
Crank Sensor Quick Fix

Crank Sensor Quick-Fix
There are two types of crank sensors, and two types of tests, the 2 and 3
wire sensors. Here are the flash points for the crank sensor testing.
1) The 2 wire crank sensor generates a voltage, and is quick tested with a
2) To test the two wire sensor, disconnect the crank sensor, ignition key
on, hook the test light to battery power, and tap at each crank sensor
terminal repeatedly. A spark click and injector pulse should be seen.
3) The 3 wire sensor has its own circuit, with 5 to 8 volt power, ground,
and signal wires. Identify the signal wire using volt meter or diagram.
4) Take the test light and connect to battery ground. With key on,
disconnect crank sensor, and repeatedly tap on the signal wire. You should
hear a spark click and injector noid pulse.
These are to test the ECM crank sensor circuit response. On both tests, you
should see a spark click and injector pulse. Crank sensor is the main input
to the ECM. If ECM working, then the crank is the only other issue. There
are other ways to test, but involve an oscilloscope and more complex. This
concludes the cranks sensor Quick-Fix.
No Crank Diagnosis (how to troubleshoot starting system problems)

starting system as well as troubleshooting on the vehicle. Even though this
is a vehicle specific case study, the information in this video is useful
for troubleshooting all starting systems.

No Crank, No Start Diagnosis - EricTheCarGuy

Whenever you have a no start condition when attempting to start your
vehicle it's important to make the distinction between "no crank, no start"
and "crank, no start" situations as they are treated differently. This
video covers what I do when confronted with a 'no crank, no start'
situation and in this case it's a worst case scenario so be sure to watch
till the end.

Ignition switch repair Plymouth Neon
Ignition switch actuator pin. Napa PN is 6201414. The MFR part number is
924-704 (Dorman) thanks user "countdingo" for looking this up
Here is a quick vid on a Plymouth neon that had a no start issue, turned
out to be a broken mechanism for the ignition switch; in this clip I will
be removing the multifunction switch, therefore that will be covered as
well. the dodge neon uses the same process
Engine Won't Start - No Crank Diagnosis (Troubleshooting Starting System Issues)
In this video I show you how to diagnose a no crank condition on a 1997
Honda Accord but the techniques shown here can be used on any vehicle.
A no crank means when the ignition switch is turned to the start position
the starter doesn't crank the engine.
To troubleshoot this issue I cover battery testing with a load tester,
solenoid trigger wire testing, and voltage drop testing with a multimeter
on the power and ground side of the starter.
I also cover how a relay works, how the starter solenoid works, and explain
what the neutral safety switch is and how it's incorporated into different
start circuit designs.

Release The Draguar! Building a Blown Jaguar Rat Rod - Roadkill Episode 7
On this episode of Roadkill, Freiburger and Finnegan do unspeakable things
to a '74 Jaguar XJ12, one of about 4,700 made. Namely, they cut a giant
hole in the hood and install a Weiand 6-71 Supercharger and twin Holley carburetors on the
350ci Chevy V8 that was already installed in the car when it was purchased
for $1,000. But things can never be easy, so the Supercharger installation is staged in the parking
lot of Gotelli Speed Shop in South San Francisco. Then the duo hits the
road, making their way to Sacramento Raceway, where they can finally
unleash "The Draguar" at the strip.
Roadkill appears every fourth Friday on the new Motor Trend channel.

Crank Position Sensor Replacement - Stalling 3800 3.8 Engine
If you have a vehicle with the GM 3800 Engine which stalls randomly and may
not always restart, then you likely have a bad crankshaft position sensor.
If your vehicle runs perfectly but the tachometer sometimes registers
incorrectly then you should replace this sensor ASAP before it leaves you
