QuestionI am experiencing the same symptoms as Brenda. It appears to be a short in the ignition switch (my key cyl lock is actually loose from the outside chrome mechanism in the column). The problem does not appear to be heat related.
Q: Do you have a diagram that shows how the fuel pump would prevent a start? My next step is to 'hot wire' around the swich (which I think is red (starter1) to red/grn (starter2) as soon as I get a multimeter.
Thanks for your help
AnswerHey John,
Do yourself a favor and just replace the switch. The parts guys at Nissan will glady key a new ignition switch to match the keys you already have. Depending on your production date is the parts are either $20 or $40.

IGNITION SWITCH - NON-MATING CONDITION BETWEEN 14401 HARNESS CONNECTOR ASSEMBLY AND IGNITION SWITCH - "NEW" SPACER FOR ATTACHING IGNITION WIRING CONNECTION TO SWITCH - VEHICLES BUILT AFTER 5/20/94 - SERVICE TIP
FORD:

LIGHT TRUCK:
1994 AEROSTAR, BRONCO, EXPLORER, F-150-350 SERIES, F-47, RANGER, VILLAGER
ISSUE:
Some vehicles may need re-work of the 14401 wiring harness. While attaching the harness connector to the ignition switch, a non-mating condition may occur. This is due to a design revision (larger tower on switch) of the ignition switch, and not having the proper spacer to clear the switch tower.
ACTION:
While re-working any 14401 harness (on affected vehicles built after 5/20/94), determine if the correct spacer (F4TB-14A468-CA) is attached to the ignition switch connector. The correct spacer will allow the "old" or "new" 14A464 connector to mate with the ignition switch assemblies F2DC-11572-AA or F4DC-11572-AA. Refer to the following service procedures.
SERVICE PROCEDURE
1. Locate connector assembly F4TB-14A464-AYA or F2TB-14A464-VA and inspect to determine if spacer F4TB-14A468-CA (Service Number F4PZ-14A468-A) is attached (Figure 1).
NOTE: THE SPACER IS GRAY AND THE PART NUMBER IS EMBOSSED ON THE FACE OF THE SPACER.
2. If spacer F2TB-14A468-HA is being used, please discard by prying off.
CAUTION: BE CAREFUL WHEN PRYING OFF THE OLD SPACER, SO THAT THE SPACER LEGS ARE NOT BROKEN OFF INSIDE THE CONNECTOR.
3. Snap on the "new" spacer F4TB-14A468-CA (Service Number F4PZ-14A468-A).

This would be the cause of a loose ignition switch. Replacing it would fix this and likely fix your issue. If you give me the production date (located in the door jamb on a white sticker) I will give you the part number. If you want to do this yourself we will walk through it. Just resubmit your question...
