Having problems with your Cars & Trucks ?

Will a knock sensor code cause a no start situation?

\015 A couple of months ago my daughter put gas into the tank of her 2003 Nissan Frontier crew cab (4x4, supercharged 3.3L V6) at a local gas station but after driving a few miles the engine went dead. Before this the truck was running okay. The truck has 80,000 miles on it and was purchased new by my daughter. After the truck stalled on the road, the engine would turn over freely but it would not start. She had it towed home and the truck sat at my home until now when I was able to finally get it to a place that I could take a look at it. All the lights appear to work although the battery required charging after sitting for so long. Checking all the fuses I could find, I found only a fuse to the outside mirrors burned. It was replaced. When I checked the trouble codes, I found a code P0328 (knock sensor) stored but no others. The rotor inside the distributor turns so I concluded that the timing belt was still intact. I then placed a spark detector on the spark plug wires and found that the distributor was putting out at least a bright orange spark to each plug. Thinking it may be a fuel problem, I changed fuel filter which was the original and it seemed to fairly dirty. Still no start. Although I could hear the old fuel pump come on for a few seconds when the key was turned on, I thought maybe the old fuel pump was going bad trying to pump through a partially clogged fuel filter. I did not have a fuel pressure tester. I then installed a new fuel pump and screen. Still no start after priming the new pump by cycling the ignition on and off at least ten times. However, now the engine seems to want to "catch" and several times it has chugged along a few seconds after the key was released but still no start.\012\012Things I have NOT done:\0121. Tried to use starting fluid (difficult to know where to spray into the supercharged engine and I don't want to damage the MAF.) \012\0122. Checked the injectors (don't really know how).\012\012I am now wondering if a weak spark has something to do with this no start condition? I am more familiar with the old breaker points, condenser and rotor type of ignitions. I am not familiar with the causes of a weak spark on an electronic ignition. Any help is appreciated.\015 Posted / edited by AnonymousUser on : 21-09-2020

Answers :

The spark should be blue not orange.
\012But given the story of how it stopped running, I would expect to find water in the gasoline.
\012Did you drain the tank and put fresh gas in when you changed the pump ?
\012Did you check with the station to see if other people had problems from the gas that day ?
\012You should be able to spray carb cleaner into any vac hose to get it into the intake manifold as a way to boost fuel to the cylinders. You may want to disconnect the fuel line at the injectors and check for water too.
