My 99 Nissan Quest was run out of gas. The starter was fried while trying to get it going. I replaced thestarter, now the van dosen't seem like its getting gas.

it sound like your van is running rich.the use of those products are not going to improve your gas consumption.instead change air filter .clean or replace air mass sensor.check tire pressure .also a bad fuel injector will make the other ones spray more gas in order to keep engine at idle

I would take it to autozone or kragen one of them should have a machine they can wheel out to the van and test the charging system for free.It will check starter,alternator,battery,the whole system.

sounds like your mechanic is just a oil changer and not a skilled technician,your Ac system needs draining on a proper machine and the amount of gas recovered weighed,then a vacumn and a additive for stop leaks added with some leak dye and the system regassed and this vehicle if the same as a nissan cargo or serena with rear AC unit should hold somewhere around 1.4 kilos of R134 gas ,note its in kilos not lbs and this is by weight not one of them cans from the local wallmart connected to the inlet port ,then when the gas is added check the pump pressure with the machine on the high pressure port ,then close the valve and allow the inlet port to draw the gas back into the system then when machine is disconnect you check the amount of gas on a recovery to make sure all the gas went into the vehicle if more than 20 grms recovered from the machine then allow it to draw some more in via the inlet port .

99's were noted for bad bearing in distributor throwing brown dust on the optical sensor in distributor. Replace distributor. $200 on ebay for reman. Used - get only 99-02 distributor.

If you tried jumping it and it still doesn't start, then it's not your battery. There may be a problem with the solenoid/starter. Try tapping the starter a few times with a metal object (tire wrench or something), but not too hard. Then try starting it again.

CAMSHAFT SENSOR BUILT IN THE DISTRIBUTOR.

Battery????
May need a new Battery??
Take it to Advance Auto parts and they will check it all for free!!
(Or a trusted Mechanic local to you..)
Make shore the wires, grounds, etc are all still in place properly!!!

Check the starter. Sounds like it is not getting any juice. Tap on it with a long metal pole or hammer while someone tries to start it.

I need a diagram of where the starter is in a 94 nissan quest van

try changing out the crankshft positioning sensor it get fire to everything.your starter could also have gone out
