My 95 nissan maxima I have replaced spark plugs, fuel pump,and coil packs. Hard to start when weather is warm but when temp is 35 and under wont start at all. Also while triing to start fuel is very strong.

could be a problem with engine electrical or still with fuel delivery. unhook a fuel injector line while it cranks and see if it shoots out spurts gas, just as the fuel pump line is supposed to shoot out a stream of gas while cranking. if you replaced the fuel pump, and no gas shoots out the disconnected fuel pump line, there is an electrical problem, (fuse, relay or wiring issue) to your new fuel pump. if the gas spurts out the loose injector line, then move on to electrical:

first ensure your ignition coil has spark by disconnecting the coil ouput lead and shorting it out to the chassis of the car. you should see a spark, when you short that circuit while cranking. if you have spark, you will have to move on to the spark plugs/ cables, then the distributor cap/coil packs.

if its part of the electrical system, it will be sensitive to temperature/humidity, and that may be why it only fails to start early in the morning. if it were the fuel injector, it would be more likely to start cold, and NOT re-start after it had already been warmed up and cut off recently.

try a little sprat of starting fluid if it run then its only the fuel flow problem.

there is code table here: code table
hope it can help u and good luck

The Spark Plugs are located under the Coil Pack in the Cylinder Head. You need to remove the silver cover on the front part of the engine which are held down by Allen Bolts to access the Coil Pack. You will need to remove the two bolts holding the Coil Pack to the Cylinder Head. Pull up on the Coil to remove the Coil and inside the hole will be the Spark Plug. The rear part of the engine next to the firewall has no cover so you will need to just remove the Coil Pack. The Nissan Maxima is very picky about the brand of Spark Plugs you replace them with, You should only use NGK Platinum Plugs or Better in your Maxima, Any other brand will make your car run rough.

Is you check engine light on? Mine was doing the same thing. I found out it was the coil packs. It could also be O2 or temp sensor... Good luck

If U haven't replaced the spark plug with that many miles I would start there. If that doesn't help U may have a bad coil pack with every spark plug has one, its what U first see when going to replace your plugs on top of manifold. Or it may be the fuel filter/sending unit.

Hope this is helpful

Remove the high tension cable to the distributor from the ignition unit. Conduct a spark test. If there's no spark, try to replace the ignition coil or the igniter.

When was the last time the spark plugs were replaced? They sell an "Engine starting fluid" that you spray directly into your air intake hose to aid in the occasional start-up problem. Have used it before, works very well.

AM temp 55 car started but stalled out after starting. Attempted to restart and did not hear fuel pump. Tried again and then fuel pump kicked in. Checking fuel pump inertial switch and fuel pump electrical supply.

You need to see if it has spark at the plugs. If it does then I suspect a clogged fuel filter or a problem with your fuel pump.
