SOURCE: wont start unless you pour gas into intake

Time for a fuel pump, but make sure chg. fuel filter and do a fuel pressure test. Thats the only sure way of knowing if its the pump is by the test.

Check for a bad temperature sensor. To check it, remove it first. Using an ohmmeter measure its resistance, which should decrease when dipped in hot water. If the the resistance remain high and doesnt change then you know it is bad, and you don't end up wasting money on buying one when it is still good.

You say t pump is coming on, but do you fuel coming up to the fuel injector rail? You can check for fuel by pushing down the valve located at the left front side of fuel rail. It looks like a tire air fill stem. Be very careful as fuel is under 40 psi pressure and can spray all over the place. do this with engine OFF and have a rag to cover the valve. Just press with tip of screwdriver and be sure valve is covered. If a little gas come out,you know you have fuel. If not gas then check fuel delivery system i.e pump, filter, lines or pickup tube.

If there is fuel in the rail, then there is most likely a problem with the control module (computer).
Check for fault codes with an OBD II reader. You can usually rent one at your local part store. You can look up fault codes to find out where the problem might lie.

More questions, just leave in comments.

Good Luck.

starting fluid is a thing of the past. dont use it. this car doesnt have a carb, its a throttle body/ electronic fuel injection system. you most likely have a fuel pump or fuel pressure regulator issue. test the fuel pressure, should be anywheres from 35-50 psi

Make sure it's getting fuel. Try using some ether or starting fluid. If it rumbles to life but doesn't stay running then there's a problem with the fuel delivery system. i.e.... Fuel pump, clogged filter, pressure regulator.... If the ether doesn't change the results you are getting now then it's a fire or sensor problem. Ignition coil, relays, sensors not signaling, PCM... I wish you luck. Let us know how it turns out

2002 Q45 infiniti Cranks but won't start


I am having the same issue on my 2002 Q45, most people that have had this problem have replaced the Starter Solenoid - You dont need to replace the whole starter, unless you have alot of miles. I ordered the part and I am going to try and install it this weekend. Almost everyone with this problem said that after replacing the solenoid the problem went away. Either do it yourself or have an independent mechanic do this, the dealer wants $900 for replacing the starter parts and labor. Solenoid is about 92 bucks online OEM.

Coming to stop sign by putting break gear slips then return to park move to drive runs. second as i drive in curves slips but as give gas enough continues running.


Just to make sure I got this right. If you come to a stop, the car won't pull again unless you put it in park? Then, if you start into a curve, the transmission starts to slip unless you give it more gas? This could be signs of a bad torque converter, failing fluid pump (not as likely), or burnt/low transmission fluid level. Check the transmission fluid after the vehicle has been driven (warm engine), leave it running, and on a level surface. Check the level twice and take the lowest reading.

Make sure the fuel pump is kicking on it won't hurt to check the relay but I have never seen one bad yet it could be the plug on the plug on the end of the wires that plugs on the pump this run hot and it burns the ends alot several fuel pumps are replaced because of this make sure you have power at the pump if you can't hear it run it will only stay powered for a few seconds and then kick off. so you might need someone to turn it on while someone checks the power.

01 ford explorer sport won't stay running. turns over fine and starts but quits right away


Check for vacuum leak at intake manifold or bad fuel pump relay or have fuel pressure checked to see if fuel pump is working properly 40-45 psi it should be pumping

Change out gears


Check and see what type of fluid they put into your tranny....I think late model Nissan/Infiniti transmissions use a slightly different fluid from other cars.
