Q1994 infinity q45 wont start please help!!

[TmaCular]

so i was having some hesistant issues with my 94 Q. did most of what was recommended. fuel filter, air filter, plugs, chevron/techtron. allthough hesistant it still had its power and ran ok. i have had it sitting for 3 weeks because it gets stored for winter as i drive something else. and when i went to start it would not start. took starting fluid to it and it finally kicked over but would not stay running unless I pumped the pedal and manually kept it at about 1500-2k rpm. i was thinking fuel pump. i have a check engine light on and will be checking it on thurs. i know a fuel pump should set it off as fuel pressure is not right. but is there anything else i should have my mechanic check when i take it to him. as i said im hoping the check engine light will point me to the problem. thanks in advance for all the help

While you're waiting for Thursday to come around, and if you suspect you may have a fuel pump or FPCU issue, and if you're a little bit mechanically inclined..... You may want to try jumpering the fuel pump to ground to see if the FPCU has gone bad.

Take off the panel in the trunk exposing the gas tank and rear deck. You can see the FPCU in the background mounted under the rear deck. Unplug it, examine the connector and FPCU for burnt connections, and then jumper the fuel pump to ground as shown in the pic. You've got to grind down the teeth of the alligator clip to get a grip on the connector and the other end of the jumper is clipped to the (unpainted) frame. If she fires up the FPCU is bad. You can also measure fuel pressure at the filter by teeing in a pressure gage. Have you heard a swarm of bees in your trunk lately?

There's lots of other things to check, including pulling the codes (see Q45.org Tech Help section) but you sound convinced about the fuel issue. Let us know what you find.

ok so my mechanic had some news for me. the fuel pump, sending unit, and all fuel system is good. the ecm is saying something about a eletric problem with the transmission.. ??? he said the car is going into a antitheft mode and shutting down the fuel pump causing it to stall. but he cant continue without a book so ? is anyone know where i can get a full service book on this car. 94 q45. and does anyone have any input on this problem. he said its not the transmission but a relay or something between them. or even if someone has some book pages of the diagrams they can copy and send me some way that would be awesome. but thanks in advance for all help

Find a qualified Infiniti certified technician QUICK,before this ape destroys your car-the Infiniti factory alarm system is NOT tied to the fuel pump,it only interrupts power to the starter to prevent unauthorized drive offs !!

More Q are destroyed by incompetent mechanics than even defective owners. Find a trained certified by Nissan TECHNICAN to do any work!\AND THEN PRAY that he sees enough Q weekly to be on top of the game.
