1990 Ford Aerostar van cranks but won't start.


it will not be a chain as you blew out the cylinders to get rid of the excess fuel by turning it over
no-- I would be looking for problem with the injector control, fuel pressure
if you have spark and compression then the thing missing is fuel

1996 ford f150 no spark to coil


Yes there is a crankshaft position sensor on this truck. I had the same issue with my 96. I changed the ICM, crankshaft sensor, and the coil. Then I found out the distributor was defective. I recommend replacing the distributor with a new one and that will correct your issue.

Where is the location and what is the appearance of the spout connector on 1993 3.0 ranger xlt ..it appears that mine is missing..would this cause engine knocking under acceleration in a high gear ??


The SPOUT connector, if disconnected, would prevent the spark from advancing. So, you would have less spark knock if disconnected. You only disconnect it when you are running a test for codes.
----------------------------------------------------------------------------------------------------------------------------------------
Disconnect the single wire in-line SPOUT connector or remove the shorting bar from the double wire SPOUT connector. (In engine comartment)
-------------------------------------------------------------------------------------------------------------------------------------
The internal circuitry of the ICM will have one of two possible arrangements, push start or computer controlled dwell (CCD). The push start system allows for increased dwell, or coil ON time, when starting the engine. The ICM on this system determines when to turn the coil ON based upon engine rpm information. The coil is then fired, or turned OFF, whenever a rising edge of a SPOUT signal is encountered (Figure 5 ). The SPOUT signal, short for SPark OUTput, is a digital signal generated by the PCM providing spark angle information to the ICM. The SPOUT signal on the push start system controls only the firing of the coil. The falling edge of the SPOUT signal is ignored. The CCD system, however, does use both edges of the SPOUT signal (Figure 6 ). The SPOUT signal for the CCD system is same as in the push start except that the falling edge is now generated to control the time at which the coil is turned ON. The coil ON time, or dwell, for this system is thus entirely controlled by the SPOUT signal. The ICM does not internally determine when to turn the coil ON as it does on the push start system. It responds directly to the SPOUT signal it receives.
In the case that the SPOUT signal line opens from the PCM, the ICM will use the PIP signal to fire the coil. This results in a fixed spark angle of and fixed dwell.

Engine just died while driving. turns over but wont start. replaced ignition coil. same problem, does not seem to be getting power to the coil. checked fuses also made suer it was getting fuel. 


Change the crankshaft sensor.That is your problem.They can fail anytime and when they do you dont get any power to the ignition coil.Let me know if you are still having problems.I think you will be fine after you have changed the sencor.Good luck m8
