Nissan Repair/1995 Nissan Maxima starting problem


Calvin -
 We have a 1995 Nissan Maxima SE w/automatic transmission.  It has about 170,000 miles on it, and has been getting harder and harder to start over the last 10-12 months.  It cranks fine, but will not catch until after a lengthy start process involving pushing the gas pedal down repeatedly.  Once started , it intermittently will stall, but usually runs fine until the next start-up.  Warm or cold, it does not seem to matter, and will be hard to start even after sitting a short time.  We hav had it into the dealer, and other mechanics, and they have determined  that it is not a fuel supply problem, but cannot diagnose it due to limited info from the computer on this model.  I have checked all applicable fuses for ignition system, and they are fine.
 Any ideas....possibly the ignition module/ignitor?  I understand this has a 'start" and a "run" mode; I guess if the "start" mode has burned out, this could result in too little spark upon starting?


Hi Dan -

Can you tell me if the check engine light is on? If so I will need the code to narrow down the issue.

If not, I have a couple tests that you can do -

I am assuming that all the spark plugs, wires, dist cap and rotor has been checked or replaced, like a tune up recently.

With that assumption, I am not too sure that the fuel system is ruled out. Please do the following tests:

Open up the throttle body rubber boot and spray some starter fluid or fuel in it. Close it up quickly and start the engine. If it starts right away, then there is a fuel issue. Probably the IAC valve, or cold start valve (but that would trigger the check engine light). If not, could be the fuel pump -

To check the fuel pump, remove the fuel line at the engine and insert the end in a non plastic container. Turn the ignition on and observe the flow. You should get a cup of fuel in the container in no longer than 3 seconds. The other test is a fuel pressure test, but you will need a pressure tester. It is an important test though, as it could cause the issue you are having. The pressure should be about 40 psi.

Let me know how this goes and then we can continue the diagnosis -

hope this helps -
