Pulled up at stop sign it shut off and I had to be pulled home. I changed plugs wires and distributor cap still won't crank. At first code reader said po303 cylinder 3 misfire and po128 coolant temperature below thermostat regulating temperature. After I changed 3 parts then no codes. But still does not crank.

Hi,

Most times when you have a crank no start condition, it is related to a fuel issue or ignition issue (no spark to the plugs).

The first thing I want you to do is to take a look through this link. It explains the most common causes of a crank no start and how to address them.

https://www.2carpros.com/articles/car-cranks-but-wont-start

If you don't see anything there that helps, I want you to try something. See if the engine starts for a couple of seconds and then stalls when using starting fluid. If it does, then we know it is a fuel-related issue. If it doesn't, I need you to check for spark at the plugs.

Here are two links you may find helpful. First, I'm adding the directions for testing fuel pressure. The second link explains the procedure for testing for spark to the plugs.

Let me know what you find or if you have other questions.

Take care,

Joe

Still not cranking! It's getting spark and getting fuel to injector since I've replaced rotor button. I can't find the pgm -fi or engine control relay under hood.

Will it start for a couple of seconds if you use starting fluid? If it does, I need you to check for an injector pulse. Here is a link that explains how it's done:

https://www.2carpros.com/articles/how-to-test-a-fuel-injector

Also, is the fuel pressure within spec?

One last question. I looked through every model and style of Frontier and none of them are showing a 2.4L as an option. I have to go to a 2001 model. Please confirm the model year and if it is a 2002, check the production date. It may have been a very early production vehicle.

Let me know.
