I have replaced all the main tune up parts such as points plugs wires cap and rotor but the engine will crank but still no spark. it is a 1988 four wins with a 5.0L omc cobra with points ignition. would the esa module cause it to not spark and is there a way to check it.
SOURCE: engine cranks ,but no spark.
ain t many more parts to electrical system left... i had same problem once n it was my ignition modulator.located under distributer.**** i can t remember,i think my car would not turn overfrom that.or only other thing could be a fuse.i 'd check every fuse too .hope this might help.

Yes. First, in the fuse block under the hood check INJ A fuse and INJ B fuse. INJ A fuse is circuit 1039 which feeds the coil. If the fuse is OK, replace the coil electrical connector. I stock 2 of these at my dealership because they are needed quite often.
FYI P1351 is an ignition coil control circuit DTC.

Hi, since you've replaced everything else, about the only thing left is the crankshaft position sensor. This is the sensor the computer uses to time the spark signals. Because this sensor is expensive, I recommend you test it first to verify it's bad before replacing. I have pasted test procedures below as well as replacement procedure in case it fails the tests. You will need an ohmmeter for the test. If you don't have an ohmmeter, you can buy one for as little as $10, or maybe you can borrow one. You will also need a timing light if you replace the sensor. Please let me know if you have questions, and thanks for using FixYa. Fig. Fig. 2: The Crankshaft Position (CKP) Sensor rotor looks like a small gear in the lower distributor housing- CRV and 1995 Odyssey models 7. Check and reset the ignition timing as outlined below. Fig. Fig. 1: The inductive lead of the timing light is placed around the No. 1 spark plug wire; and the light is aimed toward the marks on the crankshaft pulley. Fig. Fig. 2: The red ignition timing mark on the crankshaft pulley is lined up with the pointer. The two small notches on either side of the red colored notch represent the plus (+) or minus (-) 2° increments. The white notch to the far right is Top Dead Center (TDC)
TESTING CRV and 1995 Odyssey Models
CRV models: The blue and white wires. The resistance should be 300-700 ohms.
1995 Odyssey models: The blue/green and blue/yellow wires. The resistance should be 700-1,300 ohms.
REMOVAL & INSTALLATION CRV and 1995 Odyssey Models
To install:
ADJUSTMENT CRV and 4-Cylinder Odyssey Models
If equipped with an automatic transaxle, place the shifter in Park or Neutral. If equipped with a manual transaxle place the shifter in Neutral. Make sure to apply the parking brake and block the drive wheels.
Odyssey models with 4-cylinder engines: centrally located on the passenger side, under the dash. The connector has two wires; one is brown with a black tracer, and the other wire is red.
See Figures 1 and 2
The white mark on the crank pulley is Top Dead Center (TDC).
2.2L/2.3L Odyssey 2.2L models: 13-17° at 650-750 rpm
