![]() I know there were many recalls on the engine, exterior lighting and rear suspension but I never got the notices. While it's idling, it's making a very loud clunking sound. And as of this moment, the car is in the shop again. It needed time to cool off before restarting for me. It would also not start up again if I had just turned off the engine. Also, few yrs back I had the head gasket replaced cause the car would shut off while I was driving. It finally did, but it couldn't drive over 1st gear. I recently had the transmission replaced cause it just stopped while in motion and struggled to start up again. Once I do put it into drive the car will suddenly jolt forward before I'm able to start driving the car. To put the car in drive, I first have to slowly shift though each gear before finally putting into drive. The power train gear control is another waiting game. I have to turn the key, wait, turn it again, wait for the dashboard lights to come on, then finally the car will start. The electrical ignition switch to start the car has always been a problem. Its extremely low/dense lighting even after changing out the bulbs. The two front exterior headlights don't provide adequate lighting to even see the car in front of you. You can't fit more the two people in the back seat due to this issue. While driving the wheel will scrape against the wheel well. The most recently reported issues are listed below. NOTE: The battery must be fully charged for before attempting this test.The rear suspension has always been an issue. One problem related to ignition has been reported for the 2006 Nissan Altima. An LED light will not work here since the signal's frequency is so fast that you can not see it with an LED light. For this test you'll need to use a multimeter that can read Hertz frequency. If it is a fuel injected car, turn key on as you. It can only be one of 3 things, fuel, air or spark Air isnt the issue, spark probably isnt the issue. The ignition coil is activated (to spark) by the Switching signal it gets from the Altima's power transistor's Switching signal. TEST 6: Testing The Ignition Coil's Switching Signal. Resolving this power issue should solve your 'no-start no-spark' condition. If fuse is good, chance are your pump is bad. Without this voltage the ignition control module (ICM) nor the ignition coil will work. Check fuse box either in car or under bonnet (hood). In this test, you're gonna' check to see if the power transistor is being supplied with it when the engine is being cranked. OK easiest answer is if you dont hear the fuel pump prime. As mentioned in the first part of this article, it's this Triggering signal that tells the power transistor the exact time to activate the ignition coil to spark. The fuel injection computer is the one that creates and feeds the power transistor (ignition control module) the Triggering signal on your Nissan Altima. TEST 8: Testing The Triggering Signal From PCM Resolving this Ground issue should solve your 'no-start no-spark' condition. Without Ground the power transistor cannot activate the ignition coil to start sparking. Then there's a problem with the Ground circuit. Go to: TEST 8: Testing The Triggering Signal from PCM.ĬASE 2: Your multimeter DID NOT display 10 to 12 Volts. Between terminal 2 and 8 got 41. from page EC-1904 checked power transistor. I noticed that while the key/ignition was in the 'ON' position, the immobilizer light was in a constant-on state. This is good since it let's you know that the power transistor has a good path to Ground, the next step is to verify it's receiving a Triggering signal from the fuel injection computer. 2002-2006 Nissan Altima Discussion (2.5 & 3.5). Do you have 12 Volts?ĬASE 1: Your multimeter displayed 10 to 12 Volts. You should see 10 to 12 Volts on the multimeter without having to turn the key to the ON position.
