1993 Ford Ranger 4 cyl Two Wheel Drive Manual

I was driving my 93 Ford ranger and it stopped suddenly down the road and I thought maybe it had run out of gas. So I put some gas in and started to crank the motor over but because it was the side of the highway I could not hear the fuel injection pump priming. So I had it towed home. At home I checked the fuel pump and it is priming.I checked the two relays under the hood and they are good, the diode their is also good. The engine cranks over and I checked the spark plugs for spark and their is no spark. So I suspect the coil, the ignition control module or possibly the crankshaft position sensor but the crankshaft position sensor cannot be found?I would like to diagnose the ignition system but I do not know what to look for as for values and positions and where the cranksft position sensor may be or how this ignition works enitrely, and so I need some assistance detecting problems with this ignition to see if this is the problem then procede with a good diagnostic.
Thankyou

Thank you for the donation.

You listed the engine as 4 cyl so I hope I got the correct engine info for you.

It is a 2.3 L engine that I am refering to.

Did you check if the camshaft is turning while cranking? It could be a bad timing belt.

Crank Positioning Sensor is inside the timng belt cover.

Thankyou, It is to late to do it today so I will have time tomorrow afternoon, I will check the timing belt and crank sensor. How does the sensor work?Is it magnetic?Visual, some type of laser diode? So, I would know the DMM check to perform-continuity or resistance?
Also how would one check the coil, it seems like it is a DIS system one for the fuel injectors and one for the spark plugs.
Will get back to you tomorrow.I will also get more info on model.

Crank Position Sensor.

Used on 2.3L and 4.0L and mounted on front of engine behind vibration damper, sensor is a dual hall effect type with 50 percent duty cycle and an amplitude ranging between 0.4 and 13.0 volts.

There are various systems so the correct data is important.

Ok got a better look at it and it appears that the timing belt has torn and is extremely worn out. Can a person take a standard timing light and check the timing?It looks like the power stearing, alternator, harmonic balancer, all have to come out?How far would the belt slip to make timing stop an engine?Or would it be catastrophic?Their are no signs of severe damage but I will check compression just to be safe.
So I ordered a timing belt, and when I get it off I will check the crankshaft position sensor to see if it is Ok or bad.
Would one set the piston for top dead centre, and check for another mark elsewhere?

Hi again,

You did not tell me the engine type and from the info, I guess it is a 2.3L as it has a timing belt.

Some timing lights would not work on a DIS system.

The belt did not slip. The most common fault would be missing tooth on thebelt and it usually happens at the crank sprocket.

Anything more than 2 tooth out of position would cause non starting.

Yes, you have to remove the external beltings and pulleys to replace the belting.

Here are the removal and installation procedures.
Since you have a broken belt, turn the crankshaft away from TDC before attempting to get the camshaft pulley marks into position.
