I just bought a 1990 Nissan and I pride myself on trying to fix anything to do with a car but this is a bugger. I can turn the car over and it's a healthy engine but it's not firing or starting at all. The person that had it before me said it may have been from when he took the stereo out, he clipped a wire, but i checked in that area for hours and saw nothing related to the ignition. I studied wiring charts and have not found what is up. Maybe it could be the ignition module, but that's $200 bucks. And I don't want to buy one and find out it still has problems. I checked fuel but I can't check spark because the spark pugs are buried under a mess of independent coils. So what's next? thanks

Answers from the Automotive Experts

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Randy, As you know, an engine needs gas, air and spark to run. If you're having trouble starting the vehicle you must check for all of these. You can use noid lights to check if the injectors are getting a signal, but it still may be clogged and not spraying. You will need to check for spark, because this could be your problem also. Check your air filter and make sure it's not clogged. There are so many things that could be happening and without being able to look at the vehicle I'm hard pressed to tell you what that is. You should also make sure that your fuel pump is working. Obviously if you aren't getting fuel, it won't start. If the previous owner only cut the wires going to the radio, then there shouldn't be any problem there. I hope this gives you a few more ideas about what to check. You may need to take it to a certified shop to find out why it won't start. I wouldn't replace any parts unless you're sure that's the problem. Good luck. Lori Johnson
