Engine Performance problem
1993 Nissan Sentra 4 cyl Front Wheel Drive Manual

I have a 1993 Nissan sentra w/ a 1.6 ltr. Has 306000 miles and has been running great. Fuel filter has less than 3000 miles. Fuel pump has less than 40,000. I checked the timing chain and it is fine. Cannot get the engine to fire. Tried a little either and no fire. I`m at a loss as to what the problem may be

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it

I gave you a few items to check-test it and then get back with some results before we can continue.

If the computer don't see an Ne and G signals the computer will not give an IGT signal to the ignitor to fire the coil and also no IGF signal that will tell the computer that combustion has occured. Therefore No spark
