QuestionQUESTION: I have a 1994 nissan altima,and the car a has shut down and will not run. I have replaced,plugs,wires, rotor, cap, distributor,fuel filter. Pulled fuel line loose so I am getting fuel. Perhaps the ECU ? Any suggestions would be great . No check engine lights have been on at this point. Thank you in advance !
ANSWER: Curtis,
I would check for spark. If no spark you need to check the ignitor. If you have spark get a Haynes Manual and a digital volt ohm meter and check the mass airflow sensor. Email me back with what you find.

QUESTION: I am not sure where the ignitor is . I did not know this car had one, where abouts would this be located. Earlier there was ticking noise coming from the top side of the transmission when I had the key in the on position ? It is cold and rainy and dark so I will ohm the mass air in the morning.
ANSWER: Curtis,
Driver's side strut tower. The click is just the valve body servo clicking.

QUESTION: The mass air and the ignitor are fine.Found out that my fuel pump is not working correctly. Any tips to changing this pump would be great, the pump itself is housed in some sort of plastic cage? any tips? Thanks again.

Before you change the pump try a new fuel pump relay.
To change the fuel pump remove the back seat and there should be a panel you remove to get to the fuel pump.
Disconnect battery first
No open flame
No drop lights
Someone with a fire extinguisher near by
Do the fuel pump relacement with plenty of ventilation
I saw a shop in Richardson, Texas burn to the ground by a couple of guys, with a lift, doing a fuel pump replacement. The drop light fell on the ground and when the bulb popped the fuel lit and it was all over before the the Fire Truck got there. They were OK but the car and the shop and other cars in it were cooked.
Clean the top of the tank to prevent dirt and debris from falling into the tank once the pump is out
Use a new gasket/o-ring on the fuel pump where it seals against the tank
New fuel line and clamps
Buy factory since aftermarket ones tend to fail way too soon
