94 2.3 ranger
My girls truck snapped a timing belt and by accident I broke the cam sensor pulling the harmonic balancer. I changed the sensor and put a new timing belt but no spark to either side and no pulse to the injector. The check engine light comes on while cranking. Any input.
Thanx in advanced Ron |
Re: 94 2.3 ranger
This motor came from the engine machinist that rebuilt it and it was on tdc before cranking. Also the timing belt is moving forward on the crank and cam by about 1/8 " . any input on what is causing that?

Re: 94 2.3 ranger
You had it rebuilt after you broke the belt?If all you did was change the sensor,I would check and make sure it is not rubbing or got hit putting it in.If that is all you changed

Re: 94 2.3 ranger
I had to put my timing belt on my 94 2.3 off by one tooth because everytime I timed it and cranked it, it was off by one tooth. So I offset one tooth and when I cranked it, it was dead on time.

Re: 94 2.3 ranger
The motor had 220k of hard tweaker miles on it and bad compression. It came back from the engine shop on tdc. I didn't bump anything putting the motor except the the a/c condenser lightly. The belt does slip forward though. This is a very reputable shop that I took it to. I had this issue before I rebuilt the motor. I will double check the timing. I am still thinking this belt slipping forward could be a problem i guess when I getting some spark Ill find out

Re: 94 2.3 ranger
Whenyou say belt slipping do you mean on the pulley or is the pulley slipping also?
|
Re: 94 2.3 ranger
TDC on the compression stroke or exhaust stroke?
|
Re: 94 2.3 ranger
It was slipping on the timing belt cam sprocket. I am not sure about compression or exhaust. Isn't it suppose to be on the compression stroke?
|
Re: 94 2.3 ranger
Supposed to be on compression (easy to check, rotate the motor with your finger in the spark plug hole, when air rushes out/pushes finger out your heading towards compression TDC)

Re: 94 2.3 ranger
If the timing is right. Where do I go from here to find some spark. ICM then the coil pack?

Re: 94 2.3 ranger
Start simple. Pull a plug wire off a plug, lay a screw driver in it touching ground. Crank it and look for spark.
IF there is spark your good. IF not go backwards. Pull the primary wire and do the same thing. IF no spark check the two wires to the coil with key turned all the way on (like normal driving) and you should have voltage. IF no voltage go ICM |
Re: 94 2.3 ranger
no pip signal. where would that be? no pulse to injector and no spark 12v to coils and 12 volts to the ICM any more suggestions? When cranking the timing belt is slipping forward on pulleys Is that because I don't have the front cover on?
|
Re: 94 2.3 ranger
Timing belt should not slip at all. You need to retime and check the tightner.
|
Re: 94 2.3 ranger
secondary problem with the belt. Still trying to get a pulse or a spark
|
Re: 94 2.3 ranger
Sorry no cam turning = no pulse = no spark. Good luck!!
