I own a 94 ford ranger. It starts the majority of the time. When it does
not start the check-engine light that normally comes on when you turn the
key halfway forward does not come on at all. I have replaced the fuel
pump and filter, the ignition module and switch, the computer,the fuel
pump relay and the cadillidic converter. I can tell when its not going to
start because of the check-engine light. When the check- engine light
comes on when I turn the key forward it starts everytime. When its not
wanting to start the check engine light does not come on, sometimes it
takes only a few minutes of trying before it starts again, sometimes it
takes hours.The check engine light seems to be the only symptom that I
have noticed. Please help if you can!
When it doesn't start describe what happens. I'm assuming the starter
turns the motor over but the motor does not fire?
Have you checked for spark during a no start?
Have you checked fuel pressure during a no start?
The starter does turn the motor over but it does not fire. I've had one
mechanic drive it for a week to check for spark during a no start and he
said it was definitely a electrical problem so I guess it didn't spark.
I'll have to call him and double check that.
I have taken the vehicle to autozone to check for codes but they said the
check engine light has to be staying on all the time. Have you heard of
problems similar to this being caused by a faulty crank shaft sensor?
The problem's probably in either the ign switch or the EEC relay, or the
wiring in between.
Check the Relay module connections. No I dont know where it is but i found
this on autozone's site..
